AbstractA speech coding technique that yields improved speech quality over existing 2. 4 kb/s linear predictive coding vocoders is described. The method is computationally efficient and operates at a data rate of 4. 8 kb/s. Each speech frame is initially classified as voiced or unvoiced. Unvoiced frames are synthesized using a linear predictive coding filter with noise or multipulse excitation. Voiced frames are synthesized using a sum of sinusoids. The frequency of each sinusoid is defined by peaks in the frequency spectrum. An interpolation technique provides a computationally efficient method of locating the spectral peaks. A real-time, fully quantized version has been implemented in hardware.
