  • Abstract
    This paper presents a new technique for low cost robust voice compression at rate of 9.6 K bps or less. Our approach is based on applying two new concepts in voice compression; State-variable digital biquads and Punctured tree search algorithm. The digital biquads are used for real time spectral analysis of speech. The simplified multipulse excitation is generated by the punctured tree search algorithm that combines the conventional (M,L) tree search algorithm and data compression.
