Pink Trombone: exploring language and the vocal tract
Some people produce language by manipulating the vocal tract. Here is a cool way to explore that more in depth.
Pink Trombone is a clickable simulator of the vocal tract. Click or drag to move the lips, tongue, or soft palate and hear the effects immediately. See also this interactive sagittal section, which has narrower controls but more IPA support.
Anyone know the most number of language-related sounds a person could make using the vocal tract?
