Sibilant fricatives
Sibilant fricatives, one of the speech sounds, are known to be generated by a jet flow formed in the front part of the vocal tract. The sound is generated as an aeroacoustic sound when the jet flow impinges on the teeth and lips. By studying the generation mechanisms from the point of view of fluid dynamics, we are trying to improve assessment and treatment for speech disorders.
