heal.abstract	The AM-FM modulation model and a multiband analysis/demodulation scheme is applied to speech formant frequency and bandwidth tracking. Filtering is performed by a bank of Gabor bandpass filters. Each band is demodulated to amplitude envelope and instantaneous frequency signals using the energy separation algorithm. Short-time formant frequency and bandwidth estimates are obtained from the instantaneous amplitude and frequency signals and	en
