Abstract :
A novel system which employs the filter bank analysis and synthesis method for the packetisation of speech is proposed. Preliminary computer simulation studies of the system and informal subjective listening tests indicate that significant improvement in the recovered speech can be obtained, compared with the conventional technique of straight packetisation of PCM speech.
