Abstract:
A telephone apparatus with recording and playback functions comprising:a microphone (1) for receiving a first voice and generating a first voice signal;transmission signal processing means including a first a/d converter (6) for a/d-converting said first voice signal to first voice data, and a first coder (9) for coding said first voice data and generating first coded voice data;a transmission circuit (16) for generating and transmitting a transmission signal from said first coded voice data to a network;a receiving circuit (17) for receiving a reception signal from said network;a memory circuit (13, 15) for storing data and reading said stored data;switching means (12) for outputting either of said reception signal from said receiving circuit or the read data;reception signal processing means including a decoder (11) for decoding an output of said switching means, and a d/a converter (8) for d/a-converting an output of said decoder into an analog voice signal;an amplifier (5) for adding said first voice signal to said analog voice signal;voice generating (2) for generating a second voice from an output of said amplifier; andrecording signal processing means including a second a/d converter (7) for a/d-converting an output of said amplifier to second voice data, and a second coder (10) for coding said second voice data and generating second coded voice data, said memory circuit storing said second coded voice data as said data in a recording mode, said memory circuit and said switching means supplying the read data to said reception signal processing means in a playback mode.
