VoiceWarp is a free online voice changer from voicewarp.ai that processes audio and video locally in your browser and generates speech from text. It accepts microphone recordings, audio files (MP3, WAV, M4A, WebM, OGG), and video files (MP4, WebM, MOV, M4V in beta) and outputs changed audio or video that you can download. The tool is built for desktop Chrome or Edge.
What is VoiceWarp?
VoiceWarp is an online voice changer and speech generator that runs in the browser. It takes input from a microphone, uploaded audio files, or video files, and lets you apply one of 22 voice presets or adjust pitch, speed, echo, and reverb to create custom effects. The processed audio or video can be downloaded directly. For audio and video, all processing stays on your device; only the Text Voice Changer sends typed scripts to a speech generator.

- Create anonymized narration: Use the Anonymous preset to obscure identity in voice recordings.

- Edit video voice tracks: Upload a video, change the voice, and export the modified video.
How does VoiceWarp work?
The workflow follows four steps: add input (record, upload audio, choose video, or type script), choose a voice effect, preview the result, then export the output. Audio and video effects are computed locally in the tab, so you must keep the tab open while rendering. Advanced controls let you adjust pitch, speed, echo, and reverb before export.
