Telephone terminal and handle of telephone terminal

A handle of a telephone terminal, comprising a first handle end, a second handle end, a voice processing unit, and an input-output unit, wherein:

• the first handle end is configured to receive a first voice signal through a built-in microphone, and send the received first voice signal to the voice processing unit;
• the second handle end is configured to receive a second voice signal through a built-in microphone, and send the received second voice signal to the voice processing unit;
• the voice processing unit is configured to receive the first voice signal sent by the first handle end and the second voice signal sent by the second handle end, and is further configured to process the first voice signal and the second voice signal, and send the processed voice signal to the input-output unit;
• and
• the input-output unit is configured to send the processed voice signal to a communication peer.

A method for processing voice signal in a telephone terminal, wherein the telephone terminal comprises a handle and a base, the handle has a first handle end and a second handle end, and the telephone terminal has a voice processing unit which is located in the handle or in the base;

• the method comprises:
• receiving, by the voice processing unit, a first voice signal sent by the first handle end and the second voice signal sent by the second handle end, wherein, the first voice signal specifically comprises a first external voice signal and a first echo signal, wherein the first echo signal is a voice signal received back by the first handle end after a peer voice signal received from a communication peer is played by the first handle end, and the second voice signal specifically comprises a second external voice signal and a second echo signal, wherein the second echo signal is a voice signal received back by the second handle end after the peer voice signal received from the communication peer is played by the second handle end;
• performing, by the voice processing unit, echo suppression processing on the first voice signal by using the peer voice signal to obtain the processed first voice signal;
• performing, by the voice processing unit, echo suppression processing on the second voice signal by using the peer voice signal to obtain the processed second voice signal;
• generating, by the voice processing unit, the processed voice signal according to the processed first voice signal and the processed second voice signal.
