Voice Replacer

What Voice Replacer is

Voice Replacer changes the voice heard in an audio or video clip while retaining its words, timing, inflection pattern, and emotional delivery. It accepts MP3, MP4, WAV, OGG, and M4A files; clips are described as up to a few minutes long. You can select from six included voices or supply a WAV or MP3 reference recording. Five or more seconds of clean speech is described as ideal for a reference.

The tool has a browser-based DSP version and a downloadable neural version. The browser studio runs in a tab on any device and includes pitch and formant controls, EQ and tone settings, dynamics, reverb, presets, preview, and render and download. Its quality ceiling is lower than the neural version. The downloadable v0.1.1 bundle supports Windows 10/11 and requires a compatible NVIDIA GPU with at least 6 GB VRAM. It includes its model weights and runtime and is configured to work offline after download. Neural output is WAV and stays in the bundle’s app/outputs/ folder until deleted. The maker says audio is never uploaded and the tool makes no network calls apart from an optional update check, which can be disabled. Voice Replacer is free to use without an account. The current interface processes one file at a time.

Who it suits

Voice Replacer suits people who want to change a clip’s vocal identity while preserving its words and delivery. The browser version can suit users on any device who need pitch and formant controls; the neural version is for Windows users with a compatible NVIDIA GPU and at least 6 GB VRAM.

Limits
