Description

Résumé

The GCI detection is a common problem in voice analysis used for voice transformation and synthesis. The proposed innovative idea is to use a glottal shape estimate and a standard lips radiation model instead of the common pre-emphasis when computing the vocal-tract filter estimate. The time-derivative glottal source is then computed from the division in frequency of the speech spectrum by the vocal-tract filter. Indeed, prominent peaks are easy to locate in the time-derivative glottal source. A whole process recovering all GCIs in a speech segment is therefore proposed taking advantage of this. The GCI estimator is finally evaluated with synthetic signals and Electro-Glotto-Graphic signals.
