Enhanced waveform interpolative coding at low bit-rate
@article{Gottesman2001EnhancedWI, title={Enhanced waveform interpolative coding at low bit-rate}, author={O. Gottesman and A. Gersho}, journal={IEEE Trans. Speech Audio Process.}, year={2001}, volume={9}, pages={786-798} }
This paper presents a high quality enhanced waveform interpolative (EWI) speech coder at low bit-rate. The system incorporates novel features such as optimization of the slowly evolving waveform (SEW) for interpolation, analysis-by-synthesis (AbS) vector quantization (VQ) of the SEW dispersion phase, dual-predictive AbS quantization of the SEW, efficient parameterization of the rapidly-evolving waveform (REW) magnitude, and VQ of the REW parameter, a special pitch search for transitions, and… CONTINUE READING
