When transmitting speech in mobile communication systems, speech is compressed using a speech codec. To improve the speech quality, disturbing background noise and acoustic echo are attenuated. A new approach consists in embedding these methods into the speech codec. The source-coding performed by the encoder removes redundancy of the speech signal and thus the bitrate is decreased. Accordingly, the advantage of embedding the noise and echo reduction into the speech codec and performing them on the parameters decrease the complexity and permits to integrate them in network without delay or tandeming problems. In this paper we investigate a gain loss control method in the speech parameter domain. |
