FIG. 3 shows an example of a table stored in the second storage device 6, in which a plurality of users permitted to use and key codes corresponding to the users are registered. For example, user A
Is registered as "AAAA" as a corresponding password.

The first storage device 5 and the second storage device 6 can register voice information and key codes of a plurality of users, respectively, so that a plurality of users can use the portable communication device. it can.

The input unit 7 has dial keys and various function keys (not shown) for giving operation instructions to the control unit 1. The input unit 7 inputs a telephone number and selects various modes.

The display unit 8 is composed of, for example, a liquid crystal display, and displays various information such as the current time, the call duration, and the telephone number of the transmission partner under the control of the control unit 1.

The portable communication device has various modes such as a voice information registration mode for registering voice information, a key code registration mode for registering a key code, and a call mode for making a call.

Next, the operation of the portable communication device having the above configuration will be described. First, the operation of the voice information registration mode will be described. First, when the voice information registration mode is selected by a key operation on the input unit 7, the voice information registration mode is set in the portable communication device. In the audio information registration mode, the input audio is converted into an audio signal by the microphone 2, subsequently amplified by the amplifier 3, and then converted into audio data (digital signal) by the A / D converter 4. . Then, the voice analysis unit 9 analyzes the input voice data, generates voice information corresponding to the uttered voice, and outputs the generated voice information to the control unit 1. The voice information is registered in the first storage device 5 by the control unit 1 in association with the caller (see FIG. 2).

Next, the operation of the key code registration mode will be described. When the key code registration mode is selected by a key operation of the input unit 7, the key code registration mode is set in the portable communication device. In this key code registration mode, the key code input from the input unit 7 is
Is output to The key code is registered in the second storage device 6 by the control unit 1 in association with the caller (see FIG. 3).

Next, the operation in the call mode will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart for explaining the operation in the call mode. When the call mode is selected by the key operation of the input unit 7,
In the portable communication device, a call mode is set. Note that a call mode is set in an initial state, and when the power of the main body is turned on, the call mode is normally set.

As shown in FIG. 4, in this call mode,
First, the input of the voice is awaited, and when the voice is input to the microphone 2 (step S11), the input voice is
After being converted into an audio signal by the
Further, the data is converted into audio data by the A / D converter 4. Then, the voice analysis unit 9 analyzes the input voice data, and determines whether or not the voice data matches voice information registered in advance in the first storage device 5 (step S1).
2). If the result of this determination is that they match, the control unit 1 sets a dialable state (calling permitted) (step S13). If they do not match, the control unit 1 waits for a key code from the input unit 7. (Step S18).

When a key code is input from the input unit 7,
The control unit 1 compares whether the input key code matches one of the key codes registered in the second storage device 6 in advance (step S19). As a result of the comparison, if the two match, the control unit 1 sets a dialable state (call permitted) (step S1).
3) If not, the process proceeds to step S11.

When the dialing of the other party is performed by the input unit 7 after the dial is enabled, a call is made via the transmitting unit 10 and the line is connected (step S).
14), a call is made with the other party via the transmission unit 10 and the reception unit 11 (step S15). Specifically, the input voice is converted into a voice signal by the microphone 2, and then,
After being amplified by the amplifier 3, it is converted into audio data by the A / D converter 4, further subjected to modulation processing and the like by the transmission unit 10, and transmitted as a digital audio signal to the other party. On the other hand, the digital audio signal from the other party received by the receiving unit 11 is demodulated and the like, converted into an audio signal by the D / A converter 12, further amplified by the amplifier 13, and output from the speaker 14. Can be heard as voice. When the call ends, the line is disconnected (step S1).
6), the power is turned off (step S17).

As described above, in the present embodiment, voice information (identification information) corresponding to voices of a plurality of users who are permitted to use is registered in the first storage device 5 in advance. The voice analysis unit 9 determines whether the input information matches any of the registered voice information (identification information), and if these match, the control unit 1 can dial (allow the call). ), It is possible to prevent unauthorized use by a third party.

Further, in the present embodiment, the key codes respectively corresponding to the plurality of users who are permitted to use
The input voice is registered in the storage device 6, and the input voice is analyzed. If any of the voice information registered in the first storage device 5 matches, or the input key code and the second storage device 6 are matched. When any one of the key codes registered in the device matches, dialing is enabled (calling is permitted), so that it is possible to prevent a third party from using the device illegally, and it is determined that the device does not match by voice identification. In this case, dialing can be performed by inputting a key code registered in advance, and even if the tone of the voice changes due to a change in physical condition such as a cold, a call can be made.

Further, in the present embodiment, since the voice information stored in the second storage device 6 is information relating to a voiceprint, it is possible to increase the accuracy of voice identification.

The portable communication device according to the present invention is widely applicable to portable telephones, PHSs, portable information devices and the like.

Further, the present invention is not limited to the above-described embodiment, and can be carried out by appropriately changing the scope of the present invention without changing the gist of the present invention.
