Description

  The present invention relates to a portable communication terminal device having a silent response function (or a function of realizing conversation without voice).

  When a mobile communication terminal (such as a mobile phone terminal) receives an incoming call, the user may not be able to answer immediately because the user is unable to answer the incoming call (for example, the user is on a train) Case).

  In this case, any method of not answering, hanging up, or moving to a place where the user can respond (for example, getting off at the next station) is adopted.

  However, if the location cannot be changed, there is no hand other than answering the call or hanging up, and communication with the caller is not possible. In view of this point, conventionally, a proposal has been made to add a so-called silent response function to a mobile communication terminal (see Patent Document 1).

The silent response function described in Patent Document 1 is “when a call is received, a list of messages associated with the specific caller is automatically displayed on the mobile communication terminal based on the caller ID. However, when the user selects one from the message list, the message automatically flows to the caller, thereby silently (ie, without the user speaking) I can respond. "
JP 2001-168977 A

  In the above prior art, it is necessary to register the screen display message and record the response message to the caller in advance, assuming the response content to the caller in advance.

  That is, only a fixed message can be transmitted to the sender, and when an unexpected exchange occurs, a response cannot be made flexibly.

  In addition, the above-described conventional technique can only accept an incoming call response using a fixed message. Therefore, for example, when the user of the mobile communication terminal on the receiving side cannot hear the call voice (when the ambient noise is high, or when the user is a deaf person, etc.), an effective conversation is established. I can't let you.

  The present invention has been made based on such considerations, and when a mobile communication terminal receives an incoming call in a situation where an incoming call response by voice is impossible, the user of the mobile communication terminal emits a voice. The caller (calling party) can respond to the incoming call flexibly and easily, and even if the user on the receiving side cannot hear the voice of the other party, The purpose is to enable effective conversations with.

  The mobile communication terminal device of the present invention converts voice information sent from a key operation unit into voice information, or converts voice information sent from a call partner into text information. At least one of a voice recognition unit and the voice information output from the voice synthesis unit is wirelessly transmitted to the call partner, or the voice information transmitted from the call partner by wireless communication is received and A wireless communication unit capable of performing at least one of supplying to the voice recognition unit, display of character information as a transmission message input from the key operation unit, or from the other party of the call by the voice recognition unit A display unit capable of displaying at least one of character information obtained by converting voice information.

  Many portable communication terminals have a function of inputting characters and a display (display unit) that can display characters. Focusing on this point, the character input and character display function of the mobile communication terminal has been developed, the incoming response message to the call partner is input, the response message by the character is converted into voice and sent to the other party ( (Speech synthesis function) or received voice from the other party can be converted into characters and displayed on the display (display unit) (speech recognition function). It is possible to respond to the other party freely and immediately without making a call. In other words, when the user on the receiving side responds to the caller, the function to input the contents that the user wants to respond on the spot, the function to encode the contents to the voice format while confirming the input contents on the display (voice synthesis function) ), And the wireless communication function that immediately transmits the encoded data as a response message to the caller, even if there is an incoming call in a situation where it is difficult to respond by voice, In other words, it is possible to perform a silent exchange with the caller (not limited to a response message assumed in advance).

  Further, as a reverse situation, it may be assumed that the user on the receiving side can speak but cannot hear the caller's voice. To cope with this situation, a wireless communication function that receives the voice signal from the caller, a voice recognition function that recognizes the received voice and converts it into text, and a function that displays the recognized voice on the screen as characters To do. As a result, even when “the caller's voice cannot be heard”, it is possible to check the content of the caller's utterance without listening to the voice by checking the wording displayed on the screen. According to this function, it becomes possible for the hearing impaired person to freely talk with the other party using the mobile communication terminal.

  Also, it is assumed that the user's voice cannot be generated and the caller's voice cannot be heard. In this case, a combination of the above functions can be used to establish a text conversation, so that information can be exchanged flexibly and smoothly with the caller. In addition, since all the functions necessary for the present invention can be freely used by the user of the mobile communication terminal on the receiving side by operating his / her own device, the communication device of the caller (calling party) can be used. There are no restrictions and there is no burden on the other party.

  Further, one aspect of the mobile communication terminal device of the present invention is a mobile communication terminal device having the voice synthesizer, wherein a character as a transmission message is sent from the key operation unit in response to an incoming call from the call partner. When the call partner ends when the information is being input, the input character information can be transmitted to the call partner as an e-mail.

  When there is an incoming call, the caller (calling party) may end the call while creating a response message with text. If this is the case, the caller (calling party) will end the conversation without understanding what the user of the receiving device is, and will not be able to communicate at all. Is also wasted. Therefore, a function is provided in which the created response message can be sent as an e-mail as it is without performing a separate e-mail creation process. As a result, the information from the user on the incoming call side can be quickly and efficiently transmitted to the other party on the call.

  According to another aspect of the mobile communication terminal device of the present invention, the mobile communication terminal device includes the voice synthesizer. The key operation unit responds to an incoming call from the call partner as a transmission message. While the character information is being input, information indicating that a response message is being created is transmitted to the call partner.

  While preparing a response message (during character input and encoding into a voice format, etc.), the caller will be kept waiting. During this time, a synthesized message, response hold melodies, etc. stored in the mobile phone terminal in advance will be displayed. The message is sent to the caller, so that the user on the receiving side can tell the caller that a response message is currently being created. As a result, the caller (call partner) can understand the situation on the callee side and can wait for the response message to be sent with peace of mind.

  According to another aspect of the mobile communication terminal device of the present invention, a user of the mobile communication terminal device selectively switches use / non-use of the speech synthesis unit or use / non-use of the speech recognition unit. Is possible.

  At the time of an incoming call, it was difficult to respond by voice. However, the situation may change after that, and it may be possible to respond by voice. Therefore, the user can select and switch between the conversation using the silent response function (conversation realizing function without voice) or the conversation using voice as usual. When an incoming response message is entered and sent to the caller (calling party), but it becomes possible to respond by voice (conversation) after that, the voice response is immediately switched to normal voice conversation. It is possible to respond to changes and improve the convenience of mobile communication terminals.

  According to the present invention, in a mobile communication terminal, a highly convenient silent response function (transmission of response message by character input), a text call function (display by text of the other party's voice), and no voice by using both of them The conversation function (function to establish a conversation with only characters on the receiving device) can be realized.

  As a result, the user on the receiving side can transmit information by characters without making a voice, and can read the voice information transmitted from the caller as character information.

  Therefore, the user of the mobile communication terminal on the receiving side can talk freely and freely with the other party without using any voice (and listening to the voice with his / her ears). It is possible to exchange information flexibly and smoothly with the sender.

  The silent response function (and the conversation function without voice) can be freely used by the user of the mobile communication terminal on the receiving side by operating his / her own device. There is no restriction on the communication device of the other party, and there is no burden on the other party.

  In addition, even if the end of a conversation occurs during the creation of a response message using text, the end of the conversation is provided by providing a function that allows the response message to be sent as an e-mail as it is without having to create a separate e-mail. It is possible to quickly and efficiently convey information from the user on the called side to the other party.

  In addition, during a period during which the response message is being prepared, a caller (calling partner) is sent by sending a pre-stored composite message, response hold melody, or the like from the mobile communication terminal on the receiving side to the device on the calling side. Can understand the situation of the called party and can wait for the response message to be sent.

  The user can select and switch between the above-mentioned silent response function (conversation without voice function) or the normal voice conversation. This improves the usability of the mobile communication terminal.

  According to the present invention, when there is an incoming call to a mobile communication terminal under a situation where an incoming call response by voice is impossible, the user of the mobile communication terminal does not make a sound with a caller (calling partner), It is possible to respond to incoming calls flexibly and easily, and even when the user on the receiving side cannot hear the voice of the other party, an effective conversation with the other party can be performed.

  According to the present invention, it is possible to increase the functionality and enhance the added value of a mobile communication terminal device (a mobile phone terminal, a PDA having a communication function, a portable personal computer having a wireless communication function, etc.).

Next, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)

  FIG. 1 is a block diagram for explaining a basic configuration of a mobile communication terminal device (here, a mobile phone terminal) according to the present invention.

  As shown in the figure, the user of the mobile phone terminal 100 has a conversation with the user of the communication device 300 that is the communication partner via the radio base station 200.

  The mobile phone terminal 100 includes a display unit (liquid crystal display) 102, a key operation unit (keyboard capable of inputting characters) 104, a voice synthesis unit (character-speech conversion unit) 106, and a voice recognition unit (speech-to-character conversion unit). ) 108, a wireless communication unit 110, and an antenna 112, and this configuration realizes a silent response at the time of incoming call and a conversation with the other party without voice.

  Both the speech synthesis unit 106 and the speech recognition unit 108 do not necessarily need to be provided, and it is sufficient that at least one of them is provided.

  When there is an incoming call from the communication device 300 of the other party to the mobile phone terminal 100, in a situation where the user of the mobile phone terminal 100 cannot make a voice, the user performs a silent response operation using character input. Can be selected.

  That is, the user freely creates a response message via the key operation unit (keyboard) 104. The created response message is displayed on the display unit (liquid crystal display) 102, and the user confirms the created response message.

  When transmission of the response message is selected, the character information (character data) of the response message is input to the speech synthesizer (character-to-speech conversion unit 106), and the character information is encoded into speech format data (speech data). To do.

  The audio data is transmitted to the communication device 300 of the other party via the wireless communication unit 110.

  In addition, when the user of the mobile phone terminal 100 is in a situation where the call voice from the other party (the user of the communication device 300 of the other party) cannot be heard (or is a deaf person), the user Can be selected as a character display mode.

  When this mode is selected, the call voice received via the wireless communication unit 110 is encoded into character information (character data) in the voice recognition unit (speech character conversion unit). It is displayed on the display unit (liquid crystal display) 102. Therefore, the user of the mobile phone terminal 100 can recognize a transmission message from the other party using the characters.

  Thus, according to the present invention, it is possible to realize a highly convenient silent response function and a conversation function without voice.

  As a result, the user on the receiving side can transmit information by characters without making a voice, and can read the voice information transmitted from the caller as character information. Therefore, the user of the mobile communication terminal on the receiving side can talk freely and freely with the other party without using any voice (and listening to the voice with his / her ears). It is possible to exchange information flexibly and smoothly with the sender.

The silent response function (and the conversation function without voice) can be freely used by the user of the mobile communication terminal on the receiving side by operating his / her own device. There is no restriction on the communication device of the other party, and there is no burden on the other party.
(Second Embodiment)

  FIG. 2 is a block diagram showing a specific configuration of a mobile phone terminal having only a speech synthesizer. In FIG. 2, the same reference numerals are given to portions common to FIG. 1.

  As shown in the figure, the mobile phone terminal 100 controls the overall operation of the keyboard 104, the voice synthesis unit 106, the antenna 112, the wireless communication unit 120, the voice codec 122, and the mobile phone terminal 100. Input from the keyboard 104, a composite message / melody control unit 128 that transmits a composite message or composite melody for notifying the other party that a response message is currently being created, And an input unit 130 that supplies character information (character data) to the control unit 126.

  FIG. 3 is a diagram showing, in time series, an example of the interrelationship between the device operation of the user of the mobile phone terminal, the operation of the mobile phone terminal, and the state of wireless communication.

  In FIG. 3, S401 to S404 indicate main display screen forming processes of the mobile phone terminal 100. A to F indicate time points (timing on the time axis). A to F correspond to the display time points (display timings) of the display screens shown in FIG.

  As shown in the figure, at the time A, the mobile phone terminal 100 is in a standby state. When there is an incoming voice call, the cellular phone terminal 100 displays the incoming call on the display unit (not shown in FIG. 2, reference numeral 102 in FIG. 1) and notifies the user of the incoming call (S400).

  When the user responds to the incoming call, the cellular phone terminal 100 displays a busy message indicating that the call is in progress (S401: time point B).

  When the character input mode (silent response mode) is selected and a response message is input, the mobile phone terminal 100 displays a response message (S402: time point C).

  When transmission is selected, the response message is encoded (voice synthesis) into voice format data (S403: time point D).

  Subsequently, transmission processing of the voice format data (voice data) to the wireless communication network (air) is performed (time E), and the data is transmitted to the other party via the wireless communication unit 120 and the antenna 112.

  Then, the display on the display unit (reference numeral 102 in FIG. 1) of the mobile phone terminal is switched to a busy display (S404).

  FIG. 4 is a diagram showing an example of a display screen on the mobile phone terminal corresponding to each time point (each timing) in FIG. Each of A to F in FIG. 4 corresponds to the execution time (execution timing) of each procedure shown in FIG.

  As shown in the figure, the screen is a standby screen at the time point A, and the name of the other party (Taro Yamada who is the caller) is displayed on the in-call screen at the time point B. On the response message display screen at the time point C, a response message “Since we are in a conference, I will call you back later” is displayed.

  Since the other party is kept waiting during the response message creation period, a composite message, a hold melody, or the like is sent to the other party to notify that the response message is currently being created. As a result, the other party can wait for the incoming response message (that is, without worrying that there is no response).

  On the speech synthesis screen at time D, a message “Conversion is in progress. Please wait.” Is displayed. During this time, transmission of the composite message, the hold melody, etc. to the other party is continued. During this time, if the speech synthesis is canceled, the screen returns to the in-call screen (time B screen).

  When the speech synthesis is completed, the transmission screen at time E is displayed. On this transmission screen, “Sending. Please wait.” Is displayed.

  When the transmission is completed, the in-call screen at time F is displayed. In this state, a silent response can be performed again, and a normal voice response can also be performed.

As described above, in this embodiment, when a mobile phone terminal receives an incoming call, the user of the mobile phone terminal does not make a voice and responds flexibly to a free character input (a silent response with a high degree of freedom). This improves the convenience of the mobile phone terminal.
(Third embodiment)

  In the present embodiment, there is further provided a function of transmitting a response mail created on the mobile phone terminal as an e-mail as it is.

  That is, there is a case where the caller (calling party) ends the call while there is an incoming call and the user on the called side is creating a response message with text. If this is the case, the caller (calling partner) will end the conversation without understanding the situation of the user on the receiving side, and will not be able to communicate at all. In addition, a response message using characters created with great effort is also wasted.

  Therefore, a function is provided in which the created response message can be sent as an e-mail as it is without performing a separate e-mail creation process. As a result, the information from the user on the incoming call side can be quickly and efficiently transmitted to the other party on the call.

  FIG. 5 is a diagram showing another example of the interrelationship between the device operation of the user of the mobile phone terminal, the operation of the mobile phone terminal, and the state of wireless communication in time series.

  In FIG. 5, the procedure (operation) up to time point C is the same as the procedure (operation) shown in FIG. 3, and the subsequent procedure (operation) is different in FIG.

  That is, in FIG. 5, immediately after time point C, the other party ends the call (line disconnection). Then, on the display unit (liquid crystal display) 102 of the mobile phone terminal 100, a confirmation screen as to whether or not to continue creating the response message is displayed (S405: time point D).

  When the user selects to continue creating the response message (YES), the screen automatically shifts to the e-mail creation screen (S406: time point E).

  FIG. 6 is a diagram showing an example of a display screen on the mobile phone terminal corresponding to each time point (each timing) in FIG. In FIG. 6, A to E each correspond to the execution time (execution timing) of each procedure shown in FIG.

  The standby screen at time point A, the in-call screen at time point B, and the response message display screen at time point C are the same as in FIG.

  As shown in the drawing, on the confirmation screen at the time point D, a message for asking “You have been disconnected. Do you want to create a mail?” Is displayed. Here, if the user selects “NO (No)”, the screen returns to the standby screen, and if “YES (Yes)” is selected, the screen shifts to a mail creation screen at time point E.

On the E-mail creation screen at time E, the mail address of the other party (the other party who ended the call) is automatically set as the destination, and the content of the response message being created is automatically set in the text. . After that, text editing and the like can be performed as in normal mail creation. When the user selects transmission after completion of the mail text, the electronic mail is transmitted to the other party.
(Fourth embodiment)

  In the present embodiment, a case where the mobile phone terminal has only a voice recognition unit will be described. In the mobile phone terminal of this embodiment, the voice from the other party is converted into characters and displayed on the display unit (liquid crystal display). Therefore, the user can read the other party's voice by characters.

  FIG. 7 is a block diagram showing a specific configuration of a mobile phone terminal having only a voice recognition unit. In FIG. 7, parts that are the same as those in FIG. 2 are given the same reference numerals.

  The basic configuration of FIG. 7 is the same as that of FIG. 2, but in FIG. 7, a speech recognition unit 108 is provided instead of the speech synthesis unit (106), and an output unit 132 is provided instead of the input unit (130). It is different in that the composite message / melody control unit 128 is deleted.

  FIG. 8 is a diagram showing still another example of the interrelationship between the device operation of the user of the mobile phone terminal, the operation of the mobile phone terminal, and the state of wireless communication in time series.

  In FIG. 8, the procedure (operation) up to time point B is the same as the procedure (operation) shown in FIG. 3, and the subsequent procedure (operation) is different in FIG.

  That is, in FIG. 8, immediately after time point B, the user selects the character display of the voice from the other party (that is, performs mode switching selection). Then, the other party's voice signal received by the wireless communication unit 110 is supplied to the voice recognition unit 108 and converted into character information by voice recognition (S407).

  Then, a display screen using characters of the other party's voice is displayed on the display unit (liquid crystal display) 102 (S408: time point C).

  FIG. 9 is a diagram showing an example of a display screen on the mobile phone terminal corresponding to each time point (each timing) in FIG. A to C in FIG. 9 respectively correspond to the execution time (execution timing) of each procedure shown in FIG.

  In FIG. 9, when there is an incoming call, a transition is made from the standby screen (time point A) to the in-call screen (time point B). At this point B, both the partner voice and the own voice are transmitted and received as voice signals.

  Further, when the user selects the character display of the voice from the other party (that is, performs the mode switching selection), the other party voice display screen (time point C) is displayed. On the other party's voice display screen, the message “Tomorrow's meeting is scheduled, but please change the time.” Is displayed.

  In the state of this screen, both the other party's voice and one's own voice are transmitted and received as voice signals, but the received other party's voice is not output from the speaker but is displayed on the screen as characters.

Thereby, for example, even in a situation where it is difficult to hear the voice, the user of the mobile phone terminal 100 can know the message from the other party. The same applies when the user of the mobile phone terminal 100 is a hearing-impaired person.
(Fifth embodiment)

  FIG. 10 is a block diagram showing a specific configuration of a mobile phone terminal having both a voice synthesis unit and a voice recognition unit. The configuration of the mobile phone terminal shown in FIG. 10 is a combination of the configurations shown in FIGS. 2 and 7. 10, parts that are the same as those in FIGS. 2 and 7 are given the same reference numerals.

  As shown in the figure, the mobile phone terminal 100 of FIG. 10 includes both a voice synthesizer 106 and a voice recognizer 108, and selectively uses one of them to perform “silent response” or “character-based”. “Confirmation by text of message from the other party” can be realized, or both of them can be used to realize “voiceless conversation”.

  According to the mobile phone terminal 100 of FIG. 10, even when an incoming call is received under a situation where it is difficult to respond by voice, it is possible to exchange silently with the caller according to the situation.

  Further, as a reverse situation, it is assumed that the user on the receiving side (mobile phone terminal 100) can utter, but cannot hear the caller's voice. Display on the screen and check visually. If this function is used, a hearing-impaired person can also talk freely with the other party using a portable communication terminal.

  Also, it is assumed that the user's voice cannot be generated and the caller's voice cannot be heard. In this case, it becomes possible to communicate with the sender flexibly and smoothly by using the above functions in combination.

  In addition, since all the functions necessary for the present invention can be freely used by the user of the mobile communication terminal on the receiving side by operating his / her own device, the communication device of the caller (calling party) can be used. There is an advantage that there is no restriction and there is no burden on the other party.

  FIG. 11 is a diagram showing still another example of the interrelationship among the device operation of the user of the mobile phone terminal, the operation of the mobile phone terminal, and the state of wireless communication in time series.

  FIG. 11 shows an example of realizing “a conversation without voice” using both “silent response” and “confirmation by text of a message from the other party”.

  As shown in the figure, at the time A, the mobile phone terminal 100 is in a standby screen. When there is an incoming voice call in this state, an incoming call display is made (S400), and when the user of the mobile phone terminal 100 performs an incoming call response operation, the call display is switched (S401: time point B).

  Here, when the user of the mobile phone terminal 100 selects the character display mode of the other party's voice (that is, when switching the mode is selected), the voice of the other party is recognized by the voice recognition unit 108 and converted into character information. (S407). Then, a character call screen is displayed (S409: time point C).

  Next, when the user of the mobile phone terminal 100 selects the character input mode (that is, the silent response mode) and inputs a response message, the response message is displayed in characters (S410: time point D).

  Subsequently, when transmission of the response message is selected by the user of the mobile phone terminal, the voice synthesis unit 106 synthesizes the response message into voice format data (S410: time point E).

  Then, the voice signal is transmitted to the air (time point F), and the character call screen is displayed again (time point G).

  FIG. 12 is a diagram showing an example of a display screen on the mobile phone terminal corresponding to each time point (each timing) in FIG. Each of A to G in FIG. 12 corresponds to the execution time point (execution timing) of each procedure shown in FIG.

  At the time point A, the display unit (liquid crystal display) 102 of the mobile phone terminal 100 is a standby screen, and at the time point B, it is a busy screen. In this state, when a mode for displaying the other party's voice in characters is selected (that is, when mode switching is selected), a character call screen is displayed (time point C).

  On the text call screen, the message of the other party is displayed as “Tomorrow's meeting is scheduled, but please change the time”. If the mode is switched again in this state, the screen during the call at time point B is restored.

  When the user of the mobile phone terminal 100 selects the character input mode (silent response mode) in the state of the character call screen at time C and inputs a response message from the key operation unit (keyboard) 104, the response message display screen Move to (time point D). In this state, a synthetic message or a hold melody is sent to the calling party to notify that a response message is being created.

  In the character call screen (time point D) in FIG. 12, a response message “Since we are in a conference now, I will call you back later” is displayed.

  In this state, when the user of the mobile phone terminal 100 performs tail transmission selection, the speech synthesis screen (time E) is displayed. In the state of this speech synthesis screen (time E), speech synthesis processing is performed by the speech synthesizer 106. During this time, a mobile phone saying “Conversion is in progress. A message for the user of terminal 100 is displayed.

  In this state, if the user of the mobile phone terminal 100 selects cancel, the screen returns to the character call screen at time C, and if cancel is not selected, the screen shifts to the transmission screen (time E).

  In this transmission screen (time E), a message “Transmission is in progress. Please wait” is displayed below the display unit 102.

  When the transmission is completed, the screen returns to the character call screen (time point G).

  As described above, the user of the mobile phone terminal 100 can talk with the other party flexibly by using only the characters without producing any voice or listening to the other party's voice. Therefore, even if there is an incoming call in a situation where it is difficult to respond, it is possible to promptly take an appropriate response and exchange necessary information (ensuring communication).

  Also, if this function is used, even a deaf person can talk with the other party by means of characters only by operating their own keys without relying on the power of others. At this time, since voice information is transmitted to the other party, the other party can talk with the hearing impaired person in the same manner as when talking to a healthy person.

  As described above, according to the present invention, a highly convenient silent response function (and a conversation function without voice) can be realized in the mobile communication terminal. As a result, the user on the receiving side can transmit information by characters without making a voice, and can read the voice information transmitted from the caller as character information. Therefore, the user of the mobile communication terminal on the receiving side can talk freely and freely with the other party without using any voice (and listening to the voice with his / her ears). It is possible to exchange information flexibly and smoothly with the sender.

  The silent response function (and the conversation function without voice) can be freely used by the user of the mobile communication terminal on the receiving side by operating his / her own device. There is no restriction on the communication device of the other party, and there is no burden on the other party.

  In addition, even if the end of a conversation occurs during the creation of a response message using text, the end of the conversation is provided by providing a function that allows the response message to be sent as an e-mail as it is without having to create a separate e-mail. It is possible to quickly and efficiently convey information from the user on the called side to the other party.

  In addition, during a period during which the response message is being prepared, a caller (calling partner) is sent by sending a pre-stored composite message, response hold melody, or the like from the mobile communication terminal on the receiving side to the device on the calling side. Can understand the situation of the called party and can wait for the response message to be sent.

  Burden on the other party by enabling the user to select and switch between the above-mentioned silent response function (conversation without voice function) or normal voice conversation It is possible to adapt to the situation without spending time and improve the usability of the mobile communication terminal.
