Pink Trombone

PINK TROMBONE is a bare-handed speech synthesizer. Neil Thapen models the vocal tract as a set of soft, movable parts — tongue, lips, velum, vocal folds — and lets you reshape them with a mouse or touch. Every gesture changes the resonances, so vowels, fricatives, and plosives emerge from anatomy rather than recorded samples.

It is at once a toy, a demonstration of articulatory phonetics, and a reminder that speech is a physical act: the same air pressure and tissue geometry that lets us whisper also lets us sing.
