This mode can be set by the user pressing down a key button of the input unit 17, and can be set regardless of whether the mobile phone 10 is in a call.

Next, the operation of this embodiment will be described.

First, the operation until the portable telephone 10 receives a call will be described. First, a caller (not shown) makes a call from a telephone or the like to a base station (not shown). When the base station responds, the calling telephone dials the telephone number of the mobile phone 10 to the base station, and the base station connects the base stations based on the telephone number information. Is connected to a base station that controls the mobile phone 10 via a public network or an ISDN network.

When the portable telephone 10 hangs off, a wireless line is connected between the portable telephone 10 and the base station on the portable telephone 10 side. As a result, the caller's telephone and the mobile telephone 10 are connected via the switching network, and can transmit and receive voice signals.

Next, audio signals transmitted and received by the mobile phone 10 will be described. When the mobile phone 10 receives a call, a high-frequency signal transmitted via a wireless line is received by the antenna 20. The high-frequency signal is converted into a baseband signal by the transmission / reception unit 15 and output to the CPU 11. The codec 14 in the CPU 11 decodes the baseband signal and outputs it from a speaker (not shown).

Generates a character string corresponding to the input numeric string and selects a synthesized speech signal corresponding to the character string.

The character string can be generated according to a predetermined character code or the like. For example, when the character code corresponding to “A” is “11” and the user inputs “11” from the input unit 17, the CPU 11 inputs the input “11” to the voice selection unit 18. . The voice selecting unit 18 analyzes a corresponding character from the character code.

Then, the character "A" is selected from synthesized speech stored in a memory (not shown). After that, the synthesized speech “A” is output to the CPU 11 as a synthesized speech signal. When a numeric string corresponding to a plurality of characters is input, a continuous voice may be transmitted to the calling telephone by buffering all of them.

The synthesized voice signal is output to the transmission / reception unit 15. The transmission / reception unit 15 converts an audio signal that is a baseband signal into a high-frequency signal. Then, the signal is transmitted from the antenna 20 to the base station on the mobile phone 10 side via a wireless line. The high-frequency signal is transmitted to a calling-side base station (not shown), received by a calling-side telephone (not shown), and a synthesized voice is output from a speaker of the calling-side telephone.
