In the voice label registration function described with reference to FIG. 9, a level detection circuit for detecting the level of voice information input in order to improve the quality of the voice label is provided.
When the voice information is below a predetermined level, it is possible to notify the caller by a message or the like and not to register the encoded digital data as voice information in the memory. In this case, the audio information to be detected includes an analog audio signal output from the microphone 1, a digital audio signal output from the A / D converter 2, and the audio processing circuit 3.
Either of the encoded digital audio signals that are the outputs of

Similarly, in the voice label registration function, the voice label is registered as a set with the memory dial at the time of registration operation, but only the memory dial registration is performed first and the corresponding voice label registration is performed. It is possible to do it later. In this case, as the operation up to step 904 in FIG. 9, the memory dials registered in advance are sequentially confirmed on the call display unit. Furthermore, when calling this memory dial, the telephone numbers are prioritized based on the number of times telephone numbers have been called in the past, starting with the telephone number with the largest number of calls and giving priority to a predetermined number of telephone numbers. If the telephone number is frequently called and the corresponding voice label can be input, the voice label can be efficiently registered for a telephone number that is frequently used. It is also possible to register the telephone number immediately after the call as a memory dial and additionally register the abbreviation and the voice label corresponding to the telephone number.

In the voice label search function described with reference to FIG. 10, the voice information reproduced from the voice label is the voice information at the time of voice label registration inputted from the microphone 1. However, for example, it is inputted from the operation unit and registered as a memory dial. The same function can be realized by converting the abbreviated name, which is the operation information, to a coded digital audio signal using a signal conversion circuit and reproducing it through the audio processing circuit. Here, as a method of converting the operation information into the encoded digital audio signal, table information for associating the operation signal with the encoded digital audio signal is prepared in advance in the memory, and an abbreviated name as the audio information based on the table information. There is a method of converting into the encoded digital audio signal of. This table information is stored in a memory, for example, in association with a certain operation signal from the operation section, in association with the encoded digital audio signal generated by converting the operation signal through the signal conversion circuit, or from the operation section. For operation signals with
The analog audio signal input through the microphone 1 is converted through an audio processing circuit and the encoded digital audio signal is made to correspond and stored in a memory.

Similarly, in the voice label search function,
The order in which the voice labels are scrolled was the order of registration. For example, the telephone numbers related to the calling process are prioritized based on the history of the calling process in the past, and the phone numbers related to the latest calling process are given. First, if voice labels corresponding to a predetermined number of telephone numbers are preferentially converted and output as analog voice signals, an efficient voice label search can be performed.
