LPC, a statistical method for predicting future values of a
waveform on the basis of its past values1, is often used to obtain a spectral
LPC differs from formant tracking in that:
- the waveform remains in the time domain; resonances are
described by the coefficients of an all-pole filter.
- altering resonances is difficult since editing
IIR filter coefficients can result in an unstable filter.
- analysis may be applied to a wide range of
LPC is often used to determine the filter in a source-filter
model of speech2 which:
- characterizes the response of the vocal tract.
- reconstitutes the speech waveform when driven by the correct
