Voice Changer Online: Chipmunk, Robot, Deep, and More
Change your voice in the browser: record with the microphone or open a recording, pick chipmunk, deep, robot, alien, monster, telephone, or cave echo, or set the pitch, robot effect, and echo yourself, compare with the original, and download the result as WAV.
Voice Changer Online: Chipmunk, Robot, Deep, and More: Pitch changes without changing speed: the recording is cut into overlapping 60-millisecond grains, each read faster or slower and lined up with the one before, so the voice goes up or down while the words keep their timing. The robot sound multiplies the voice by a steady tone, the telephone sound keeps only 300 to 3,400 Hz with a little distortion, and echo repeats the sound every 220 milliseconds.

Semitones

Frequently asked questions
Does it work live, while I talk?
No: record first, then change it. That keeps the result clean and lets you try every voice on the same take.
Why does a big pitch change sound artificial?
Shifting a voice by more than a few semitones moves its natural resonances along with the pitch, which is what gives the chipmunk and monster voices their character.
Can I use a video's sound?
Yes: open the video file, and its sound track is used.
