# Bark
|
26 |
+
|
27 |
+
Bark is a transformer-based text-to-audio model created by [Suno](https://www.suno.ai).
|
28 |
+
Bark can generate highly realistic, multilingual speech as well as other audio - including music,
|
29 |
+
background noise and simple sound effects. The model can also produce nonverbal
|
30 |
+
communications like laughing, sighing and crying. To support the research community,
|
31 |
+
we are providing access to pretrained model checkpoints ready for inference.
|
32 |
+
|
33 |
+
The original github repo and model card can be found [here](https://github.com/suno-ai/bark).
|
34 |
+
|
35 |
+
This model is meant for research purposes only.
|
36 |
+
The model output is not censored and the authors do not endorse the opinions in the generated content.
|
37 |
+
Use at your own risk.
|
38 |
+
|
39 |
+
The following is additional information about the models released here.
|
40 |
+
|
41 |
+
## Model Usage
|
42 |
+
|
43 |
+
```python
|
44 |
+
from bark import SAMPLE_RATE, generate_audio, preload_models
|
45 |
+
from IPython.display import Audio
|
46 |
+
|
47 |
+
# download and load all models
|
48 |
+
preload_models()
|
49 |
+
|
50 |
+
# generate audio from text
|
51 |
+
text_prompt = """
|
52 |
+
Hello, my name is Suno. And, uh — and I like pizza. [laughs]
|
53 |
+
But I also have other interests such as playing tic tac toe.
|
54 |
+
"""
|
55 |
+
audio_array = generate_audio(text_prompt)
|
56 |
+
|
57 |
+
# play text in notebook
|
58 |
+
Audio(audio_array, rate=SAMPLE_RATE)
|
59 |
+
```
|
60 |
+
|
61 |
+
[pizza.webm](https://user-images.githubusercontent.com/5068315/230490503-417e688d-5115-4eee-9550-b46a2b465ee3.webm)
|
62 |
+
|
63 |
+
|
64 |
+
To save `audio_array` as a WAV file:
|
65 |
+
|
66 |
+
```python
|
67 |
+
from scipy.io.wavfile import write as write_wav
|
68 |
+
|
69 |
+
write_wav("/path/to/audio.wav", SAMPLE_RATE, audio_array)
|
70 |
+
```
|
71 |
+
|
72 |
+
## Model Details
|
73 |
+
|
74 |
+
Bark is a series of three transformer models that turn text into audio.
|
75 |
+
|
76 |
+
### Text to semantic tokens
|
77 |
+
- Input: text, tokenized with [BERT tokenizer from Hugging Face](https://huggingface.co/docs/transformers/model_doc/bert#transformers.BertTokenizer)
|
78 |
+
- Output: semantic tokens that encode the audio to be generated
|
79 |
+
|
80 |
+
### Semantic to coarse tokens
|
81 |
+
- Input: semantic tokens
|
82 |
+
- Output: tokens from the first two codebooks of the [EnCodec Codec](https://github.com/facebookresearch/encodec) from facebook
|
83 |
+
|
84 |
+
### Coarse to fine tokens
|
85 |
+
- Input: the first two codebooks from EnCodec
|
86 |
+
- Output: 8 codebooks from EnCodec
|
87 |
+
|
88 |
+

### Release date
|
97 |
+
April 2023
|

+
## Broader Implications
|
100 |
+
We anticipate that this model's text to audio capabilities can be used to improve accessbility tools in a variety of languages.
|
101 |
+
|
102 |
+
While we hope that this release will enable users to express their creativity and build applications that are a force
|
103 |
+
for good, we acknowledge that any text to audio model has the potential for dual use. While it is not straightforward
|
104 |
+
to voice clone known people with Bark, it can still be used for nefarious purposes. To further reduce the chances of unintended use of Bark,
|
105 |
+
we also release a simple classifier to detect Bark-generated audio with high accuracy (see notebooks section of the main repository).
