Bark is a universal text-to-audio model created by [Suno](www.suno.ai), with code publicly available [here](https://github.com/suno-ai/bark). \ Bark can generate highly realistic, multilingual speech as well as other audio - including music, background noise and simple sound effects. \ This demo should be used for research purposes only. Commercial use is strictly prohibited. \ The model output is not censored and the authors do not endorse the opinions in the generated content. \ Use at your own risk. """ article = """ ## 🌎 Foreign Language Bark supports various languages out-of-the-box and automatically determines language from input text. \ When prompted with code-switched text, Bark will even attempt to employ the native accent for the respective languages in the same voice. Try the prompt: ``` Buenos días Miguel. Tu colega piensa que tu alemán es extremadamente malo. But I suppose your english isn't terrible. ``` ## 🤭 Non-Speech Sounds Below is a list of some known non-speech sounds, but we are finding more every day. \ Please let us know if you find patterns that work particularly well on Discord! * [laughter] * [laughs] * [sighs] * [music] * [gasps] * [clears throat] * — or ... for hesitations * ♪ for song lyrics * capitalization for emphasis of a word * MAN/WOMAN: for bias towards speaker Try the prompt: ``` " [clears throat] Hello, my name is Suno. And, uh — and I like pizza. [laughs] But I also have other interests such as... ♪ singing ♪." ``` ## 🎶 Music 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. Try the prompt: ``` ♪ In the jungle, the mighty jungle, the lion barks tonight ♪ ``` ## 🧬 Voice 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. ## 👥 Speaker Prompts 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. Try the prompt: ``` WOMAN: I would like an oatmilk latte please. MAN: Wow, that's expensive! ``` ## Details Bark model by [Suno](https://suno.ai/), including official [code](https://github.com/suno-ai/bark) and model weights. \ Gradio demo supported by 🤗 Hugging Face.
