Joint estimation of formant trajectories via bayesian techniques and adaptive segmentation

摘要

The invention relates to the field of automated processing of speech signals and particularly to a method for tracking the formant frequencies in a speech signal, comprising the steps of:
- obtaining an auditory image of the speech signal;
- sequentially estimating formant locations;
- segmenting the frequency range into sub-regions;
- smoothing the obtained component filtering distributions; and
calculating the exact formant locations.
