BIRDSPEECH

About

BIRDSPEECH is a browser tool that turns a voice recording into birdsong. It tracks the voice's pitch and loudness, discards the rest of the sound, and synthesizes a new tone six times higher by default, so melody, rhythm, and inflection survive but words do not. Users can upload audio or video, record a microphone, and adjust pitch, timbre, trill, reverb, and voice range.
