Modeling and processing speech with sums of AM-FM formant models
Shan Lu, Peter C. Doerschuk · 2002
We describe a new approach to decomposing signals that are modeled as a sum of jointly amplitude and frequency modulated cosines with slowing-varying center frequencies observed in noise based on statistical nonlinear filtering ideas. We demonstrate the ideas on a formant tracking problem for the sentence "Where were you while we were away".
