Abstract

There is provided a voice activity detector (VAD) (40) for assisting the voice quality enhancement in the uplink direction of a mobile communication system in which the voice quality enhancement means (50) are embodied in the transcoding and rate adapting unit (TRAU) (2). The VAD (40) comprises means (41, 42) for performing both a spectral analysis and an energetic analysis on a received speech signal and means (43, 45) for processing the results of said analysis and taking a decision on audio segment nature. The VAD performs spectral analysis directly on the coded signal. <IMAGE>
