For RVC git clone https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI and train your model or point the code to you model (must clone RVC repo in bark-with-voice-clone directory)
If you want to clone a voice just follow the clone_voice.ipynb notebook. If you want to generate audio from text, follow the generate.ipynb notebook.
To create a voice clone sample, you need an audio sample of around 5-12 seconds
You will get the best results by making generations with your cloned voice until you find one that is really close to the source. Then use that as the new history prompt (comes from the model so should theoretically be more consistent)
Huge shoutout & thank you to:
gitmylo for the solution to the semantic token generation for better voice clones and finetunes (HuBERT, etc.)

To save audio_array as a WAV file:
from scipy.io.wavfile import write as write_wav
write_wav("/path/to/audio.wav", SAMPLE_RATE, audio_array)Bark supports various languages out-of-the-box and automatically determines language from input text. When prompted with code-switched text, Bark will attempt to employ the native accent for the respective languages. English quality is best for the time being, and we expect other languages to further improve with scaling.
text_prompt = """
Buenos días Miguel. Tu colega piensa que tu alemán es extremadamente malo.
But I suppose your english isn't terrible.
"""
audio_array = generate_audio(text_prompt)miguel.webm
Bark can generate all types of audio, and, in principle, doesn't see a difference between speech and music. Sometimes Bark chooses to generate text as music, but you can help it out by adding music notes around your lyrics.
text_prompt = """
♪ In the jungle, the mighty jungle, the lion barks tonight ♪
"""
audio_array = generate_audio(text_prompt)lion.webm
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_{0-9}.
text_prompt = """
I have a silky smooth voice, and today I will tell you about
the exercise regimen of the common sloth.
"""
audio_array = generate_audio(text_prompt, history_prompt="en_speaker_1")sloth.webm
Note: since Bark recognizes languages automatically from input text, it is possible to use for example a german history prompt with english text. This usually leads to english audio with a german accent.
You can provide certain speaker prompts such as NARRATOR, MAN, WOMAN, etc. Please note that these are not always respected, especially if a conflicting audio history prompt is given.
text_prompt = """
WOMAN: I would like an oatmilk latte please.
MAN: Wow, that's expensive!
"""
audio_array = generate_audio(text_prompt)latte.webm

Bark has been tested and works on both CPU and GPU (pytorch 2.0+, CUDA 11.7 and CUDA 12.0).
Running Bark requires running >100M parameter transformer models.
On modern GPUs and PyTorch nightly, Bark can generate audio in roughly realtime. On older GPUs, default colab, or CPU, inference time might be 10-100x slower.
Similar to Vall-E and some other amazing work in the field, Bark uses GPT-style models to generate audio from scratch. Different from Vall-E, the initial text prompt is embedded into high-level semantic tokens without the use of phonemes. It can therefore generalize to arbitrary instructions beyond speech that occur in the training data, such as music lyrics, sound effects or other non-speech sounds. A subsequent second model is used to convert the generated semantic tokens into audio codec tokens to generate the full waveform. To enable the community to use Bark via public code we used the fantastic EnCodec codec from Facebook to act as an audio representation.
Below is a list of some known non-speech sounds
