|
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. |

|
|
## 🌎 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! |
|
``` |
|
|
