Abstract :
Vector Quantization is applied to modify a 2400 bps LPC vocoder to operate at 800 bps, while retaining acceptable intelligibility and naturalness of quality. The design of this speech compression system is discussed and compared to other very low bit rate vocoders. Advantages of vector quantization over a scalar technique are examined in detail, and several new properties are presented.
