The SpAA Lab -Speech Accommodation to Acoustics brings together brings together faculty and students interested in Speech Intelligibility, Room Acoustics and Musical Acoustics as well as in voice production and perception. The long-term goal of our research is to discover acoustical conditions in classrooms that minimize teachers’ vocal effort preserving high speech intelligibility for pupils. Our research concerns classroom acoustic for enhancing students’ understanding, effect of room acoustics on vocal effort and fatigue, and vocal health in teacher and singers.
