PPT-On the (Glottal) Inverse Filtering of Speech Signals

An introduction CS578Digital speech signal processing Invited lecture On the Glottal Inverse Filtering of Speech Signals Introduction Inverse Filtering Techniques Conclusions Introduction On the Glottal Inverse Filtering of Speech Signals. This requires however that the precise locations of the Glottal Closure Instant GCIs are available The focus of this paper is the evaluation of automatic methods for the detection of GCIs directly from the speech waveform Five stateoftheart GCI dete P 37 1002 Tunis Tunisia Africa phone 216 71 874 700 fax 216 71 872 729 email aichabouzidenitrnutn NEllouzeenitrnutn ABSTRACT Nowadays new techniques of speech processing such as speech recognition and speech synthesis use the glottal clo sure and N.Ellouze@enit.rnu.tn ABSTRACT Nowadays, new techniques of speech processing such as speech recognition and speech synthesis use the glottal clo-sure and opening instants. Recognition techniques use t Basic idea is pretty simple: As a speaker goes from low to medium to high f0, the obvious changes in glottal pulse rate are often accompanied by significant changes in what’s called the . mode of phonation.
