ABSTRACT:
In an echo suppressor for suppressing an echo resulting from acoustic coupling in a telephone apparatus, an attenuator attenuates a transmission signal level with reference to a first level signal representative of a level of a reception speech signal which is supplied to the telephone apparatus. Supplied with the reception speech signal through an input terminal, the first detecting arrangement detects the reception speech signal to produce the first level signal. It is a matter of course that a receiver converts the reception speech signal into a reception speech sound. A microphone produces a transmission speech signal in response to a transmission speech sound.
