This microphone is connected to the telephone main body by a cord as shown in Figure 2, or it is cordless, in which the microphone has a built-in transmitter and a receiver built into the telephone main body, or the microphone is connected to the telephone main body. It is also possible that it is equipped with. FIG. 3 is a block diagram of the configuration of this automatic dialing type mobile phone. Refer to Figure 3.

Reference numeral 10 denotes a voice analysis means for extracting the feature quantity of the voice inputted from the voice input unit 9; and 11, in the registration state, the feature quantity extracted by the voice analysis means is registered in the voice standard pattern memory 14 as a voice standard pattern, and is recognized. In the state, a voice recognition means compares the input voice pattern with a voice standard pattern and outputs information such as the address of the closest standard pattern; 12 is information such as the address outputted by the voice recognition means 11 and key information; Based on the information from the input section, information such as the telephone number and name of the other party is registered in the information memory 15 or searched from the information memory 15 to display the display section 3, the voice synthesis section 16, and the dial number sending section 17.
13 is a key information input section for inputting the telephone number and character string in the registration state; 14 is a plurality of parties for dialing each caller; The voice standard pattern memo IJ-116, in which the voice indicating the destination is registered as the standard voice, is a memory for information such as the telephone number and name of the required party, and the voice standard pattern memory 14 and the information memory 16 are both memories for external storage. Included in car door. 16 is a search processing unit 12
In order to confirm that the telephone number, name, etc. of the destination party outputted from the device have been received, the voice synthesis means generates the name, etc. as a voice feature quantity and outputs it to the speaker 8; This is a dial number sending unit that dials a number.

The operation of the automatic dialing type mobile phone configured as described above will be explained below.

In FIGS. 1, 2, and 3, when registering the voice of the memory card user, first, when the name of the other party is voice input through the microphone 9, the voice analysis means 10 inputs the voice of the other party. After the feature quantity extraction of the speech pattern is performed and the speech recognition means 11 that receives the extract confirms that the same speech feature quantity has not already been registered in the speech standard pattern memory 14, The system enters a registration standby state for registering feature amounts.

At the same time, information such as an address is output to the search processing section 12.

At this time, information such as the telephone number and name of the other party input from the key information input section 13 is displayed on the display means 3 via the search processing section 12, and after visually checking it, the memory ink 6 is pressed. As a result, each of the voice standard patterns whose information such as telephone number and name is in the voice standard pattern memory 14 and is in a standby state is registered in the information memory 16.

Next, when the caller's voice is recognized and automatic dialing is performed, when the name of the other party is input by voice through the microphone 9, the voice analysis means 10 extracts the features of the input voice pattern. Voice recognition means 1 that received this
