As shown, the exchanger 201 for storing and managing a plurality of types of voice announcements, and to extract any voice announcements stored in the database 305 based on the control command. Receives a control command memory 303 for storing voice guidance control information provided from and a control command of the switch 201, extracts a control code corresponding to the control command from the control command memory 303, Control unit 301 for reading the voice announcements corresponding to the control code from the database 305, and a text / voice conversion unit for converting the voice announcements provided from the control unit 301 into an analog voice signal 307, a PCM converter 309 for converting the voice signal into a PCM signal, and an output signal of the PCM converter 309 by converting the output signal into voice data in a predetermined format. It is composed of audio data conversion section 311 for providing a heat exchanger (201).

The PCM converter 309 modulates the analog voice signal provided by the text / voice converter 307 according to the PCM modulation method and converts the analog voice signal into A-law PCM format voice data. The voice data converter 311 converts the voice data of the A-law PCM format output from the PCM converter 309 into voice data of the u-law format.

The A-law PCM format voice data is used in the European telephone network as the ITU-T companding standard used to convert between analog and digital signals in PCM systems, and the mu-law standard is used in North America. . In addition, the u-law type voice data is a companding technique commonly used in North America, and is standardized to 64 Kbps CODEC in ITU-T G.711. Therefore, it will be obvious that the standard method applied in the present invention may vary depending on the system environment.

On the other hand, the controller 301 is interlocked with the data input unit 313 for modifying the pre-registered announcement, or input a new announcement.

Hereinafter, the operation of the present invention will be described.

First, the voice guidance server 205 is spaced apart from the switch 201 and interconnected through a predetermined communication line. The voice guidance server 205 holds a plurality of types of voice guidance comment information, and each voice guidance comment information includes a unique code. The unique code may be referred to as an address for a voice announcement stored in a database.

The switch 201 is applied to a public telephone network (PSTN) or a mobile communication network, and is connected to a plurality of exchanges for accessing the subscriber station 203 through a call or performs connection with another subscriber station. In this case, the subscriber station 203 may request a connection with another subscriber station by using the switch 201, and a predetermined voice announcement may be provided to any one subscriber station in the course of the call connection. .

For example, the subscriber station 203, which is the sender, may be notified that there is no absence state for another subscriber station that is the receiver, and the switch 201 voices the caller that the absence state is absent. That is, after the exchange 201 connects the call path between the caller and the receiver in response to the caller's request, the switch 201 recognizes that the receiver's incoming call is not made for a certain time. The switch 201 recognizes that the incoming delay time for the receiver terminal exceeds the reference value, and generates a control command for voice guidance. The control command is transmitted to the voice guidance server 205 according to a preset protocol.

The control command is transmitted through a communication line connected between the switch 201 and the voice guidance server 205. Therefore, the voice guidance server 205 may be spaced apart from the switch 201 with sufficient space for the administrator's convenience. This is to facilitate the processing of the voice announcements stored in the voice guidance server 205 by the administrator, and also to facilitate the replacement of the database 305 in which the voice guidance comment is stored. The database 305 is a compact disc (CD), a hard disc (HD), or a separate recording and storage medium, and has a structure that can be attached to and detached from the voice guidance server 205.

Thereafter, the control command sent from the switch 201 is provided to the control unit 301 of the voice guidance server, and the control unit 301 recognizes the reception of the control command and enables the control command memory 303. . The control unit 301 reads out the unique code (or address number) of the voice announcement corresponding to the currently received control command from the control command memory 303.

The controller 301 stores the unique code information for the voice announcement as an internal register. The controller 301 reads pre-stored voice announcement information into the database 305 based on the unique code information stored in the register. The textualized data is information input through the data input unit 313 and is input by an administrator. Thus, the administrator can implement corrections, changes, new registrations, etc. for the textualized data.

Meanwhile, in the present invention, the voice announcement information is described as textual data, but may be digital voice data as necessary. The digital voice data is converted into data of a predetermined capacity by sampling analog voice guidance information. After the corresponding digital voice data is generated using a separate A / D converter, the digital voice data is stored in the database 305. do.

Thereafter, the controller 301 provides the voice announcement information, that is, the textualized text information, read from the database 305 to the text / voice converter 307. The text / voice conversion unit 307 converts the text information into an analog voice signal, which converts the text information into voice data in the form of a voice file. The text / voice converter 307 provides the voice data to the PCM converter 309. The PCM converter 309 modulates the voice data according to the PCM modulation method and converts the voice data into voice data of a predetermined format.

The converted voice data may be, for example, A-law PCM format voice data or mu-law voice data. The A-law PCM format voice data is an ITU-T companding standard used to convert between analog and digital signals in a PCM system. Thereafter, the voice data output from the PCM converter 309 is provided to the voice data converter 311. The voice data converter 311 converts the voice data in the A-law PCM format or the voice data in the mu-law format into voice data in the u-law format. The u-law format voice data is a companding technique generally used in North America. The format of the voice data may be different depending on the standard method applied.

As a result, the voice data output from the voice data converter 311 is provided to the switch 201, and the switch 201 transmits the voice announcement corresponding to the voice data to the corresponding subscriber terminal connected to the current call. 203).

As described above, the system for providing announcements according to the present invention implements a voice guidance server having voice announcement information and is spaced apart from an exchange for transmitting voice guidance, thereby modifying and converting voice announcement information. It is easy to add work.

In addition, since the voice guidance server is provided separately from the switchboard, when an output error of the voice guidance announcement occurs, a quick replacement or repair is possible, thereby improving the quality of the voice guidance service.
