Intelligibilité du message vocal filtré par bandes d'intensité

Abstract

The authors have worked on lists of logatomes, words and sentences by filtering the intensity in 3 pass-bands. And intelligibility index has been determined. The lower band has a very low index in contrast to that of the middle (which is the best) and high band. An interpretation is done in consideration of the acoustic structure of the vocal material (formants, etc.).

Key Words:

• Speech distortion
• Low-level band
• Middle-level band
• High-level band
• Intelligibility index
