Mediumband speech encoding using time domain harmonic scaling and adaptive residual coding

This paper describes the study of a new approach to speech digitization at mediumband bit rates of 9.6 to 16 Kb/s. The technique is based on a combination of Time Domain Harmonic Scaling and an Adaptive Residual Coder. Computer simulation studies have shown that this technique is able to produce excellent quality speech at the bit rates in question.
