Electroacoustic methods of determining the parameters of speech sound generator

The spectrum character of speech wave is connected with the fundamental frequency (F0) of human vocal folds vibration. As it is considered, F0 of the source during voicing contains an abundance of information on the larynx pathology, individual trait, the emotional state and ethnographic origin of speaker. The present paper presents results of research that conducted simultaneous measurement of fundamental frequency of vocal fold vibration by the electroglottography (EGG) and with the acoustic methods. The analysis of the F0 function exactitude and the usefulness of these methods were executed too
