Résumé

It is known that most of the laryngeal pathologies produce a change in the vocal quality of the patient. The pitch period (To) is significantly affected by these diseases. In most of the pathological voices there are present: (a) large deviations of To and in magnitudes of the peaks of the pitch; (b) deformation of the shape of pitch impulses; (c) abrupt changes in To and the magnitude of the peaks of the pitch; (d) interruptions of pitch generation during sustained vowel phonation-voice breaks; (e) noisy components having a significant amplitude. In order to overcome these difficulties a method is proposed for calculating To by analysis of different domains of the signal
