 ### 🎤 Voice Presets and Voice/Audio Cloning
 
-Bark has the capability to fully clone voices - including tone, pitch, emotion and prosody. The model also attempts to preserve music, ambient noise, etc. from input audio. However, to mitigate misuse of this technology, we limit the audio history prompts to a limited set of Suno-provided, fully synthetic options to choose from for each language. Specify following the pattern: `{lang_code}_speaker_{number}`.

 Bark is a series of three transformer models that turn text into audio.
 ### Text to semantic tokens
- - Input: text, tokenized with [BERT tokenizer from huggingface](https://huggingface.co/docs/transformers/model_doc/bert#transformers.BertTokenizer)
