Laryngeal Level Amplitude Modulation In Vibrato, Christopher Dromey, Lorie Reese, J. Arden Hopkin

Faculty Publications

Objectives: The goal of this investigation was to test a new methodology for measuring amplitude modulation (AM) at the level of the vocal folds during vibrato in trained singers, because previous research has suggested that AM arises in large part as an acoustic epiphenomenon through an interaction of the harmonics in the laryngeal source with the resonances of the vocal tract as the fundamental frequency oscillates.
Study Design: A within-subjects model was used to compare vocal activity across three pitch and three loudness conditions.
Methods: Seventeen female singers with a range of training and experience were recorded with a microphone …
