We implemented a real-time variable-frame-rate LPC vocoder operating at an average rate of 2000 bits/s. We also tested our mixed- source model as part of the vocoder. To improve the reliability of the extraction of LPC parameters, we implemented and tested a range of adaptive lattice and autocorrelation algorithms. For data rates above 5000 bits/s, we developed and tested a new high-frequency regeneration technique, spectral duplication, which reduces the roughness in the synthetic speech. As part of an overall very-low-rate speech compression system, we designed and implemented a program for phonetic synthesis from diphone templates. The lengthy process of extracting the 3000 needed diphone templates has been half completed.
