Voice changing and dubbing studio that keeps the original performance
Altered is a voice transformation studio. It changes the voice in a recording while keeping the performance: you upload dialogue or record live, choose a target voice, and the tool re-synthesises it with the same timing and intonation. Beyond voice changing it dubs recordings into other languages while preserving the speaker's timbre, and clones voices so a character or presenter sounds consistent across a series. It is used in animation, game dialogue, podcasts and advertising, where the same performer cannot be booked for every line and where age, gender or accent has to change convincingly.
