VoiceCraft

What is VoiceCraft?

Very recently, one of the most innovative tools in zero-shot speech editing and text-to-speech applications has been realized: VoiceCraft. It turns out to be outstandingly suitable for a broad range of diverse data sources, such as audiobooks, internet videos, and podcasts. Trusting token infilling neural codec language models, VoiceCraft sets a gold standard in performance for speech editing and zero-shot TTS tasks.

This tool clones or changes a voice, previously unheard, within seconds and with minimal reference input. It proves especially useful when one intends to edit or generate speech in data sources that are uncontrolled, characterized by high variability.
