TRANSMITTER WITH AN IMPROVED SPEECH ENCODER AND DECODER

Document Type and Number:

WIPO Patent Application WO1999003097

Kind Code:

A3

Abstract:

In a speech encoder (4), a speech signal is encoded using a voiced speech encoder (16) and an unvoiced speech encoder (14). Both speech encoders (14, 16) use analysis coefficents to represent the speech signal. According to the present invention the analysis coefficients are determined more frequently when a transition from voiced to unvoiced speech or vice versa is detected.
