It includes a storage unit that stores information in association with information indicating any of the processes. The control unit extracts the voice of the part whose frequency characteristics are not irregular from the voice input to the voice input unit as the user voice, causes the voice output unit to output the extracted user voice, and the voice output unit outputs the user voice. When a predetermined time elapses without accepting a cancellation instruction for canceling the user voice after outputting, the information stored in the storage unit in association with the user voice among a plurality of processes is stored. If the processing shown above is executed and the cancellation instruction is received before the predetermined time has elapsed after the voice output unit outputs the user voice, the above processing is not executed.

According to the present invention, since the voice of the portion whose frequency characteristics are not irregular is extracted as the user voice from the voice input to the voice input unit, the recognized voice is input due to the inclusion of aperiodic noise. It is possible to prevent the contents of the voice instruction from being erroneously recognized. In addition, the user can confirm whether or not the user's voice is accurately recognized by checking the voice output by the voice output unit, which improves the convenience of the visually impaired user. .. Further, if the cancellation instruction is received before the predetermined waiting time elapses after the user voice is output, the process corresponding to the user voice is not executed, so that the process not intended by the user is executed. Can be reliably prevented.

[motion]
FIG. 3 is a flowchart showing the voice instruction recognition process. Hereinafter, the operation of the image forming apparatus 1 will be described with reference to FIG. 3 and the like.

The administrator of the image forming apparatus 1 inputs a display instruction for displaying a setting screen for setting the operation mode of the image forming apparatus 1 to either a normal mode or a voice mode via the operation unit 16. It is assumed that Here, when the normal mode is set as the operation mode of the image forming apparatus 1, the control unit 10 receives the instruction input via the operation unit 16 as the user's instruction. When the voice mode is set, the control unit 10 receives an instruction input by voice via the voice input unit 22 as a user's instruction.

FIG. 4 is a diagram showing an example of a setting screen. With reference to FIG. 4, when the control unit 10 receives the above-mentioned display instruction via the operation unit 16, the display unit 15 causes the display unit 15 to display the setting screen 40. At this time, the control unit 10 displays the radio button 41 for selecting the normal mode and the radio button 42 for selecting the voice mode on the selection screen 40. It is assumed that the administrator confirms the selection screen 40 and touches the radio button 42. When the control unit 10 detects a touch operation on the radio button 42 via the touch panel 16B, the control unit 10 causes the radio button 42 to display a check.

The control unit 10 also has a radio button 43 for selecting a setting for performing operation guidance only by voice and a radio button 44 for selecting a setting for performing operation guidance by voice and display on the selection screen 40. And are displayed. It is assumed that the administrator confirms the selection screen 40 and touches the radio button 43. When the control unit 10 detects a touch operation on the radio button 43 via the touch panel 16B, the control unit 10 displays a check on the radio button 43.

After touching the radio button 43, it is assumed that the administrator touches the soft key 45 for confirming the selected content. When the control unit 10 detects a touch operation on the soft key 45 via the touch panel 16B, the control unit 10 stores the selection content reflected on the setting screen 40 in the HDD 17 as the setting content for the operation mode. After touching the soft key 45, the administrator turns off the power of the image forming apparatus 1.

It is assumed that the user of the image forming apparatus 1 turns on the power of the image forming apparatus 1 after the power is turned off by the administrator. With reference to FIG. 3, when the power of the image forming apparatus 1 is turned on, the control unit 10 starts the voice instruction recognition process, and the voice mode is set based on the setting contents stored in the HDD 17. It is determined whether or not it is (step S10).

In this case, since the radio button 42 is touched by the administrator and the voice mode is set, the control unit 10 determines that the voice mode is set (YES in step S10), and the voice input units 22A to 22C is activated (step S11).

When the voice input units 22A to 22C are activated, the A / D conversion circuit of the voice input unit 22A generates the first voice data by converting the analog signal based on the voice input to the microphone into a digital signal. The generated first audio data is input to the control unit 100. Similarly, the voice input unit 22B generates the second voice data based on the voice input to the microphone of the voice input unit 22B, and inputs the generated second voice data to the control unit 100. The voice input unit 22C generates a third voice data based on the voice input to the microphone of the voice input unit 22C, and inputs the generated third voice data to the control unit 100.

After the processing of step S11, the control unit 10 determines whether or not the voice indicated by the first to third voice data input to the control unit 100 includes the user voice (step S12). Specifically, in step S12, the control unit 10 first performs Fourier transform on the voice waveforms indicated by the first to third voice data to correspond to the first to third voice data. The first to third frequency spectra to be used are acquired. The first to third frequency spectra show frequency characteristics within the claims.

When the control unit 10 has a portion showing periodicity in common to the first to third frequency spectra, the voice indicated by the first to third voice data includes the user voice. (YES in step S12). On the other hand, in the control unit 10, the first to third frequency spectra are irregular and do not show periodicity, and there is a portion that shows periodicity in common with the first to third frequency spectra. If not, it is determined that the voice indicated by the first to third voice data does not include the user voice (NO in step S12).

At this time, it is assumed that aperiodic noises such as door opening / closing sounds and keyboard keystroke sounds generated around the image forming apparatus 1 are input to each of the microphones of the voice input units 22A to 22C. To do. In this case, since the first to third frequency spectra are irregular and do not show periodicity, the control unit 10 determines that the voice indicated by the first to third voice data does not include the user voice. Then (NO in step S12), the process of step S12 described above is repeated.

In such a situation, it is assumed that the user stands in front of the image forming apparatus 1 and utters the voice "copy." At this time, since peaks in a specific frequency band appear periodically in the first to third frequency spectra, the control unit 10 includes the user voice in the voice indicated by the first to third voice data. It is determined that this is the case (YES in step S12), and the user voice is extracted from the voice indicated by the first voice data (step S13).

Specifically, in step S13, the control unit 10 identifies and extracts the spectrum of the frequency band in which the periodic peak appears in common to the first to third frequency spectra, and extracts the extracted spectrum. On the other hand, by performing the inverse Fourier transform, voice data indicating the user voice (hereinafter, referred to as “extracted data”) is generated. As a result, the control unit 10 extracts the voice of the portion where the frequency characteristic is not irregular, that is, the voice of the portion where the frequency characteristic shows periodicity from the voice indicated by the first voice data. Here, in step S13, the user voice is extracted only from the first frequency spectrum because the user voice is most clearly input to the voice input unit 22A provided on the front side of the image forming apparatus 1. This is because it is assumed.

After the process of step S13, the control unit 10 determines whether or not to perform the operation guidance only by voice based on the setting contents stored in the HDD 17 (step S14). In this case, since the radio button 43 is touched by the administrator and the setting for performing the operation guidance only by voice is selected, the control unit 10 determines that the operation guidance is performed only by voice (in step S14). YES), the voice output unit 23 is made to output the extracted user voice (step S15).

Specifically, in step S15, the control unit 10 inputs the extracted data and the confirmation voice data stored in the HDD 17 to the voice output unit 23 in this order. As a result, the voice output unit 23 outputs the user voice and the confirmation voice in this order. In this case, the voice output unit 23 outputs the user voice "copy" and the confirmation voice "do you want to do it?" In this order.

On the other hand, when the radio button 44 is touched by the administrator and the setting for performing the operation guidance by voice and display is selected, the control unit 10 determines that the operation guidance is not performed only by voice (in step S14). NO), the voice output unit 23 is made to output the extracted user voice, and the display unit 15 is made to display the content indicated by the extracted user voice (step S16).

Specifically, in step S16, the control unit 10 causes the voice output unit 23 to output the user voice and the confirmation voice in this order in the same manner as in the process of step S15 described above. The control unit 10 also uses a general voice recognition technique to recognize the content of the voice from the waveform of the user voice indicated by the extracted data, convert the recognized voice content into text, and generate text data for output. The control unit 10 arranges the character string indicated by the output text data and the confirmation character string indicated by the confirmation text data stored in the HDD 17 in this order, and causes the display unit 15 to display the content indicated by the user voice. .. In this case, the control unit 10 displays the character string "copy" and the confirmation character string "do you want to do it?" On the display unit 15 in this order.

After the processing of step S15 or step S16, the control unit 10 determines whether or not the cancellation instruction for canceling the user voice is accepted (step S17). The control unit 10 gives a cancel instruction when a new user voice is included in the voice indicated by the first to third voice data input to the control unit 100, or when the cancel key 16A is pressed. Is accepted (YES in step S17). On the other hand, the control unit 10 receives a cancellation instruction when the voice indicated by the first to third voice data described above does not include a new user voice and the cancel key 16A is not pressed. It is determined that there is no such (NO in step S17).

In this case, since the user voice of "copy" is accurately recognized by the image forming apparatus 1, the user does not make a new utterance and does not press the cancel key 16A. Therefore, the control unit 10 determines that the cancellation instruction has not been received (NO in step S17), and determines whether or not a predetermined waiting time has elapsed since the process of step S15 or step S16 was executed. Judgment (step S18).

The waiting time is not particularly limited, but here, the predetermined waiting time is assumed to be "10 seconds". The administrator inputs the standby time in advance via the operation unit 16, and the control unit 10 stores the input standby time in advance in the HDD 17 as a setting content. If it is within 10 seconds after the process of step S15 or step S16 is executed, the control unit 10 determines that the predetermined waiting time has not elapsed (NO in step S18), and the process of step S17. Return to.

When 10 seconds have passed without the user performing a new utterance or pressing the cancel key 16A, the control unit 10 determines that a predetermined waiting time has elapsed (YES in step S18), and the user The information stored in the HDD 17 is read in association with the voice, and the process indicated by the read information is executed (step S19).

Specifically, in step S19, the control unit 10 recognizes a voice from the waveform of the user voice indicated by the extracted data by using a general voice recognition technique, converts the recognized voice into text, and converts the recognized voice data into text. Generate. The control unit 10 reads from the HDD 17 the information stored in association with the text data indicating the same character string as the character string indicated by the recognition text data. In this case, the control unit 10 reads from the HDD 17 the information indicating the copy process, which is stored in association with the text data indicating the same character string as the character string "copy" indicated by the recognition text data.

The control unit 10 executes the process required to execute the process indicated by the read information. In this case, the control unit 10 causes the voice output unit 23 to output a voice indicating an operation guide for making various settings for the copy process, and the display unit 15 makes a copy for making various settings for the copy process. Display the screen. After the process of step S19, the control unit 10 ends the voice instruction recognition process.

If the user makes a new utterance or presses the cancel key 16A before the predetermined waiting time elapses, the control unit 10 determines that the cancel instruction has been accepted (in step S17). YES), the process returns to step S12.

Further, when the radio button 41 is touched by the administrator and the normal mode is set, the control unit 10 determines that the voice mode is not set (NO in step S10), and the voice instruction recognition process. To finish. In this case, the control unit 10 causes the display unit 15 to display a home screen for selecting one of a plurality of processes that can be executed by the image forming apparatus 1.

According to the above embodiment, the control unit 10 extracts the voice of the portion whose frequency characteristics are not irregular from the voice input to the voice input units 22A to 22C as the user voice, and the extracted user voice is the voice output unit. When a predetermined waiting time elapses without accepting the cancellation instruction after the voice output unit 23 outputs the user voice to the 23, the information stored in the HDD 17 in association with the user voice is stored in the HDD 17. If the above-mentioned processing is executed and the cancellation instruction is received before the above-mentioned waiting time elapses, the above-mentioned processing is not executed.

As a result, the voice of the portion whose frequency characteristics are not irregular is extracted as the user voice from the voice input to the voice input unit 22A. Therefore, the recognized voice includes aperiodic noise, so that the input voice is obtained. It is possible to prevent the content of the instruction from being erroneously recognized. Further, since the user can confirm whether or not the user's voice is accurately recognized by checking the voice output by the voice output unit 34, the convenience of the visually impaired user is improved. To do. Further, if the cancellation instruction is received before the predetermined waiting time elapses after the user voice is output, the process corresponding to the user voice is not executed, so that the process not intended by the user is executed. Can be reliably prevented.

Further, according to the above embodiment, the control unit 10 identifies and extracts the voice of the portion that commonly shows periodicity in the frequency characteristics of the voice input to the voice input units 22A to 22C as the user voice. To do. As a result, the user voice can be accurately extracted from the voice input to the voice input unit 22A, and the content of the input voice instruction is erroneously recognized due to the aperiodic noise included in the recognized voice. This can be prevented even more reliably.

Further, according to the above embodiment, the control unit 10 causes the voice output unit 34 to output the user voice, and causes the display unit 15 to display the content indicated by the user voice. As a result, the user can confirm whether or not the user voice is accurately recognized by checking not only the voice output by the voice output unit 34 but also the content displayed on the display unit 15. .. Therefore, the convenience of not only visually impaired users but also hearing impaired users is improved.

Further, according to the above embodiment, the control unit 10 receives a cancellation instruction via the voice input units 22A to 22C or the operation unit 16. Therefore, even if the user is a visually or hearing impaired user, the cancellation instruction can be easily input, and the convenience of the user is further improved.

(Other variants)
In the above embodiment, the control unit 10 sets only one standby time, but the present invention is not limited to such an embodiment. For example, the control unit 10 may set a different standby time for each process corresponding to the user voice according to an instruction from the administrator or the like input via the operation unit 16. As a result, it is possible to set an appropriate waiting time according to the user's intention for each process corresponding to the user voice, so that the convenience of the user is further improved.

The control unit 10 may also be configured not to set a waiting time for at least one of the copy process, the print process, and the scan process. In this case, when the process corresponding to the user voice is at least one of the above-mentioned processes, the control unit 10 executes at least one of the above-mentioned processes without waiting for the elapse of the waiting time. Executes the processing of. As a result, for example, for time-consuming processes such as copy processing, printing processing, and scanning processing, it is not necessary to wait for the elapse of the waiting time, so that the processing corresponding to the user voice is completed after the instruction by the user voice is input. It is possible to prevent the user from waiting too long before doing so.

Further, in the above embodiment, the control unit 10 directly extracts the user voice from the first frequency spectrum, but the present invention is not limited to such an embodiment. For example, the control unit 10 stores in advance the frequency spectrum of periodic noise such as motor sound generated from a motor provided in the image reading unit 11, the image forming unit 12, the feeding unit 14, or the like in the HDD 17. When extracting the user sound, the frequency spectrum of the periodic noise may be first removed from the first frequency spectrum, and the user sound may be extracted from the first frequency spectrum after the removal. As a result, even when the recognized voice contains periodic noise, it is possible to prevent the content of the input voice instruction from being erroneously recognized.

Further, in this case, when the value indicating the degree of similarity between the frequency spectrum of the periodic noise and the first frequency spectrum is equal to or more than a predetermined value, the control unit 10 may, for example, "give the voice instruction again. It may be configured to prompt the re-input of the user voice by outputting a message such as "Please go" to the voice output unit 23 or displaying it on the display unit 16. As a result, it is possible to more reliably prevent the content of the input voice instruction from being erroneously recognized.

Further, in the above embodiment, the control unit 10 extracts the user voice only from the first frequency spectrum, but the present invention is not limited to such an embodiment. For example, the control unit 10 may extract the user voice from each of the first to third frequency spectra. In this case, the control unit 10 may be configured to synthesize the three extracted user voices by a general voice synthesis technique and output the synthesized user voices to the voice output unit 23.

Further, in the above embodiment, the control unit 10 displays the setting screen 40 as a setting screen for setting the operation mode of the image forming apparatus 1 to either the normal mode or the voice mode. It is not limited to such an embodiment. For example, the control unit 10 may display a setting screen including an image that can be recognized by a user without color vision deficiency and cannot be recognized by a user with color vision deficiency.
