The authors present results of an acoustic criterions analysis made next to 57 subjects, who had undergone total laryngectomy or total pharyngolaryngectomy, between 6 months and 3 years before. The study allows to assess, next to 29 tracheoesophageal voices and 30 oesophageal voices, the fundamental frequency, the vocal extensive, the maximum phonation time, and the study of pauses (number and time) in a reference sentence. The acoustic advantages of phonatory prothesis are confirmed, but the oesophageal voice knowledge must not be forgotten.
