Abstract
A telephone terminal (10) includes: an operation unit (11) inputting an operation signal corresponding to an operation of a user; a sound input unit (16) inputting a sound signal corresponding to sound captured from an outside; a signal processing unit (14) converting the sound signal from the sound input unit to a transmission signal; a control unit (15) interrupting propagation of the sound signal inputted to the signal processing unit at the time when the operation signal from the operation unit is recognized. With the configuration, sound generated by a terminal operation such as a key operation during a telephone call in a telephone terminal can be easily prevented from being sent to the other party.

A telephone terminal comprising:
- an operation unit inputting an operation signal corresponding to an operation of a user;
- a sound input unit inputting a sound signal corresponding to sound captured from an outside;
- a signal processing unit converting the sound signal from the sound input unit to a transmission signal and transmitting the transmission signal to a telephone line;
- and
- a control unit interrupting propagation of the sound signal inputted to the signal processing unit at the time when the operation signal from the operation unit is recognized.
A signal processing method, for a telephone terminal being in a communication state where the telephone terminal converts a sound signal corresponding to sound captured from an outside to a transmission signal and transmits said transmission signal to a telephone line, comprising a step of interrupting propagation of the sound signal in the telephone terminal.
