Modeling and quantization of speech magnitude spectra at low data rates-evaluating design trade-offs
Adelle Smith, Tenkasi V. Ramabadran, M.J. McLaughlin · 2002
Several designs for modeling and quantizing the discrete harmonic amplitudes in voiced speech spectra are investigated. A cumulative distortion measure is computed for each design. This measure is shown to provide useful insight for evaluating design trade-offs.
