Abstract
- Abstract: Complex AM and FM signal models can be used for parametric modeling of speech signals. Complex AM signal model has been found to be suitable for voiced speech phonemes, whereas complex FM signal model can be used for representation of unvoiced speech phonemes. This article explains the basic principles of parameter estimation of these two models, and presents techniques for fast on-line processing of speech data and automated model fitting.
