Voice Replacer changes the vocal identity in an audio or video clip while preserving its words, timing, inflection contour and emotional delivery.
What Voice Replacer is
Voice Replacer changes the vocal identity in an audio or video clip while preserving its words, timing, inflection contour and emotional delivery. It accepts MP3, MP4, WAV, OGG and M4A files, with clips described as up to a few minutes. Users can select from six included voices or provide a WAV or MP3 reference clip; five or more seconds of clean speech is described as ideal. The browser-based DSP version runs in a tab on any device and provides pitch and formant controls, EQ, tone and dynamics settings, reverb, presets, preview, and render and download options. Its quality ceiling is lower than the neural tool. The downloadable v0.1.1 neural bundle is for Windows 10/11 and requires a compatible NVIDIA GPU with at least 6 GB VRAM. It includes model weights and runtime and is configured for offline use after download. The maker says audio is not uploaded and the tool makes no network calls except an optional update check, which can be disabled. The free tool requires no account and processes one file at a time.
