  In FIG. 8, when the main control unit 201 receives a mail read-out request signal from the slave unit 101a via the data bus 223 (step S101), the main control unit 201 uses the RAM 203 based on the information of the slave unit 101a that issued the request. The registered contents of the requesting child device 101a are checked with reference to the registered contents (step S102), and then the main control unit 201 determines whether or not a special setting for audio output to the child device 101a has been made. Is determined (step S103).

  If the result of determination in step S103 is that no special setting has been made for audio output to the child device 101a, a default sound signal registered in advance is transmitted to the child device (step S107), and this process ends. . On the other hand, as a result of the determination in step S103, when the special setting for the audio output to the child device 101a is made, the main control unit 201 determines whether or not to accept a mail reading request from the child device 101a. (Step S104) If not accepted, a read-out prohibition setting notification not accepting a mail read-out request is given to the slave unit 101a via the wireless unit 210 (Step S108), and then this process ends.

  As a result of the determination in step S104, when receiving a mail reading request from the child device 101a, the main control unit 201 determines whether or not a speech synthesis signal is set by a speech synthesis signal setting process of FIG. 10 or FIG. Is determined (step S105).

The display (FIG. 7) is terminated, a notification that speech synthesis from the own terminal is not performed is sent to the FAX 100 (step S407), and this processing is terminated.

  If “OK” is selected as a result of the determination in step S402, the own terminal is designated by pressing the down arrow key of the selection key 606 (step S403) (FIG. 7). The own terminal is designated by selecting Yes in the “designation” item. Next, the cursor is sequentially set to “voice selection (high temperature, normal, low temperature)”, “volume (high, medium, low)”, and “speed (fast, normal, slow)”, and change settings are made respectively (step S404). If the change setting is completed (YES in step S405), the corresponding voice synthesis signal pattern is registered in the RAM 303 in advance based on the designation setting information of the terminal itself and the voice selection, volume and speed setting information. A predetermined speech synthesis signal pattern is set by searching from the obtained data (step S406). Next, in step S407 described above, the FAX 100 is notified that speech synthesis is not performed from its own terminal. End the process.

  Also, if the result of determination in step S403 is that there is no slave unit designation setting, or if the result of determination in step S404 is that there is no output sound quality change setting, the main control unit 301 transmits a default audio signal to its own terminal. (Step S407), the process is terminated.

  According to the processing in FIG. 11, the voice synthesis signal pattern of the own terminal can be set on the handset 101 side.
