The intelligibility of the 800 bits/s vocoders is generally lower than with 2400 bits/s vocoders. The main reasons appear to be the quantization of the short term predictor, the poor definition of the transients, the lack of naturalness of the synthesized speech. We present a new and simple 800 bit/s vocoder which has the fundamental property of concentrating the coding effort on what appears, to be the most important for intelligibility, naturalness, and subjective quality.
