Why it's useful

Give it a few seconds of a reference voice and a line of dialogue and it reads it back in that voice, with an exaggeration setting that takes it from flat to theatrical. Good for placeholder or final barks, narration and tutorial lines in over 20 languages. Weights are MIT.

What it needs

An NVIDIA graphics card is best; Apple Silicon and CPU work more slowly. Python 3.11. Every clip carries an inaudible Resemble watermark. Only clone voices you have permission to use.
