Résumé

Laryngeal mechanism 0 (M0) can be found in speech and some types of singing. Vocal fry, pulse register, creaky voice, glottal fry are the terms frequently used to refer to this vocal production. Our aim is to investigate the different vibratory patterns that can be involved in M0 thanks to high speed cinematography and to compare them with the EGG signal. The analysis shows that different realizations of M0 can be found in this corpus especially when comparing (i) the M0 realized with vocal effort from (ii) the M0 realized without vocal effort. The first one is more likely to be characterized by a single pulse, while the second one is frequently produced with multiple pulses - both realizations having different typical EGG shapes. We also found that in the case of single pulse pattern, the anterior portion of the vocal folds is more involved in the vibrating process than the posterior one, while the posterior portion of the vocal folds can also be active in the case of a multiple pulse pattern.
