  Next, the operation of the present embodiment will be described in detail with reference to FIG.

  FIG. 3 is a flowchart for explaining the operation of the present embodiment.

  In FIG. 3, when the controller unit 9 of the mobile phone 100 with a voice conversion function detects an incoming call (step S101) and key data indicating that the response button is pressed is input from the key input unit 10 (step S102). The controller unit 9 acquires a caller telephone number (hereinafter referred to as a caller number) from the incoming message, and determines whether or not the caller number has been acquired (step S103).

  If the caller number can be acquired (YES in step S103), it is confirmed whether or not the caller number is registered in the telephone directory stored in the storage device included in the controller unit 9 (step S103). S104). If the caller ID is registered in the phone book (YES in step S104), a signal instructing the voice processing unit 6 not to perform voice conversion is output to start a call (step S109). ). Voice conversion of this call is not performed, and a call with normal voice is performed.

  If the caller ID cannot be acquired (NO in step S103), the controller unit 9 refers to the voice conversion setting data stored in the storage device included in the controller unit 9, and the voice conversion setting data is valid. Whether it is invalid or not (step S105). If the voice conversion setting data is valid (YES in step S105), a signal instructing the voice processing unit 6 to perform voice conversion is output to perform voice conversion (step S107). A call for conversion is started (step S108). If the voice conversion setting data is invalid (NO in step S105), the voice conversion is not performed, so that the process proceeds to step S109 and a normal voice call is started.

  If the caller number can be acquired (YES in step S103) and the caller number is not registered in the phone book (NO in step S104), the controller is the same as in step S105. The unit 9 refers to the voice conversion setting data stored in the storage device included in the controller unit 9 and confirms whether the voice conversion setting data is valid or invalid (step S106). If the voice conversion setting data is valid (YES in step S106), the process proceeds to step S107, and a signal instructing the voice processing unit 6 to perform voice conversion is output to perform voice conversion. . If the voice conversion setting data is invalid (NO in step S106), since voice conversion is not performed, the process proceeds to step S109, and a normal voice call is started.

  When a call for voice conversion is started in step S108, the uplink voice input from the microphone 3 is A / D converted by the voice codec unit 7 and input to the voice processing unit 6. Since the audio processing unit 6 is instructed to perform audio conversion by an instruction signal from the controller unit 9, the A / D-converted uplink audio from the audio codec unit 7 is converted into audio via the audio conversion changeover switch 60. It is passed to the recognition unit 61 and divided into phonemes (sequences), and the phonemes (sequences) are passed to the speech conversion unit 62 for speech conversion and encoded by the encoding unit 63. The encoded uplink voice is output from the antenna 1 via the transmission / reception unit 5.

  After the call for voice conversion is started in step S108, the controller unit 9 determines whether or not to cancel the call for voice conversion (step S110). In order to cancel a call for voice conversion, that is, to make a normal call without voice conversion, the voice conversion stop key of the key input unit 10 may be pressed. When the voice conversion stop key is pressed, this key data is input to the controller unit 9, and the controller unit 9 identifies the key data and recognizes that the voice conversion is canceled (step S111).

  When it is determined to cancel the call for performing the voice conversion (YES in step S110), the controller unit 9 outputs a signal instructing the voice processing unit 6 not to perform the voice conversion to stop the voice conversion ( Step S112). Then, a normal voice call without voice conversion is performed, and when the call ends (step S113), the processing of the controller unit 9 is ended.

  If the call for performing voice conversion is not canceled (NO in step S110), the call for performing voice conversion is continued, and when the call ends (step S114), the controller unit 9 instructs the stop of the voice conversion process. Is output to the voice processing unit 6, the voice conversion process is stopped (step S115), and the process of the controller unit 9 is terminated.

  As described above, according to the present embodiment, in response to an incoming call in which the caller telephone number is not notified and the call partner cannot be specified, the uplink voice is converted into voice and transmitted to the call partner. This voice is not specified, and it is possible to make a call with peace of mind.

  Also, if the caller's phone number is notified but the caller's phone number is not registered in the phone book, voice conversion is performed assuming that the other party cannot be specified. You can talk with confidence.
