Improving the performance of LPC-CVSD tandem connections by phase modification
Thomas P. Barnwell III, Ronald W. Schafer · 2005
This paper describes an approach to modifying the waveshape of LPC synthetic speech, which involves a combination of spectral flattening prior to estimation of the LPC parameters and non-minimum phase de-emphasis following conventional LPC synthesis. Results indicate that significant modifications of the synthetic waveform can be effected.
