Chatterbox
Expressive voices in 23 languages – and voice cloning from just a few seconds of audio.
DifficultySome experience
HardwareNVIDIA GPU recommended, Colab T4 is enough
LicenseMIT
Chatterbox from Resemble AI generates very natural-sounding speech, including in German. Give it a short voice sample and it imitates the voice. Only clone voices you have permission to use.
