Changes to suno/bark

This duplicated repo allows to pass a voice preset besides the text input when using an inference client. See handler.py for details. Example:

python

import numpy as np
from huggingface_hub import InferenceClient

client = InferenceClient(model="<my-inference-url>")
sentence = "hello my name is suno"
audio_raw = client.post(json={'inputs': sentence, 'voice_preset': "v2/en_speaker_0",})
audio = np.array(eval(audio_raw)[0]['generated_audio'][0],)

Bark

Bark is a transformer-based text-to-audio model created by Suno. Bark can generate highly realistic, multilingual speech as well as other audio - including music, background noise and simple sound effects. The model can also produce nonverbal communications like laughing, sighing and crying. To support the research community, we are providing access to pretrained model checkpoints ready for inference.

The original github repo and model card can be found here.

This model is meant for research purposes only. The model output is not censored and the authors do not endorse the opinions in the generated content. Use at your own risk.

Two checkpoints are released:

Example

Try out Bark yourself!

Bark Colab:

Hugging Face Colab:

Hugging Face Demo:

You can run Bark locally with the 🤗 Transformers library from version 4.31.0 onwards.

First install the 🤗 Transformers library and scipy:

pip install --upgrade pip
pip install --upgrade transformers scipy

Run inference via the Text-to-Speech (TTS) pipeline. You can infer the bark model via the TTS pipeline in just a few lines of code!

python

from transformers import pipeline
import scipy

synthesiser = pipeline("text-to-speech", "suno/bark-small")

speech = synthesiser("Hello, my dog is cooler than you!", forward_params={"do_sample": True})

scipy.io.wavfile.write("bark_out.wav", rate=speech["sampling_rate"], data=speech["audio"])

Run inference via the Transformers modelling code. You can use the processor + generate code to convert text into a mono 24 kHz speech waveform for more fine-grained control.

python

from transformers import AutoProcessor, AutoModel

processor = AutoProcessor.from_pretrained("suno/bark-small")
model = AutoModel.from_pretrained("suno/bark-small")

inputs = processor(
    text=["Hello, my name is Suno. And, uh — and I like pizza. [laughs] But I also have other interests such as playing tic tac toe."],
    return_tensors="pt",
)

speech_values = model.generate(**inputs, do_sample=True)

Listen to the speech samples either in an ipynb notebook:

python

from IPython.display import Audio

sampling_rate = model.generation_config.sample_rate
Audio(speech_values.cpu().numpy().squeeze(), rate=sampling_rate)

Or save them as a .wav file using a third-party library, e.g. scipy:

python

import scipy

sampling_rate = model.config.sample_rate
scipy.io.wavfile.write("bark_out.wav", rate=sampling_rate, data=speech_values.cpu().numpy().squeeze())

For more details on using the Bark model for inference using the 🤗 Transformers library, refer to the Bark docs.

Suno Usage

You can also run Bark locally through the original [Bark library]((https://github.com/suno-ai/bark):

First install the bark library
Run the following Python code:

python

from bark import SAMPLE_RATE, generate_audio, preload_models
from IPython.display import Audio

# download and load all models
preload_models()

# generate audio from text
text_prompt = """
     Hello, my name is Suno. And, uh — and I like pizza. [laughs] 
     But I also have other interests such as playing tic tac toe.
"""
speech_array = generate_audio(text_prompt)

# play text in notebook
Audio(speech_array, rate=SAMPLE_RATE)

pizza.webm

To save audio_array as a WAV file:

python

from scipy.io.wavfile import write as write_wav

write_wav("/path/to/audio.wav", SAMPLE_RATE, audio_array)

Model Details

The following is additional information about the models released here.

Bark is a series of three transformer models that turn text into audio.

Text to semantic tokens

Input: text, tokenized with BERT tokenizer from Hugging Face
Output: semantic tokens that encode the audio to be generated

Semantic to coarse tokens

Input: semantic tokens
Output: tokens from the first two codebooks of the EnCodec Codec from facebook

Coarse to fine tokens

Input: the first two codebooks from EnCodec
Output: 8 codebooks from EnCodec

Architecture

Model	Parameters	Attention	Output Vocab size
Text to semantic tokens	80/300 M	Causal	10,000
Semantic to coarse tokens	80/300 M	Causal	2x 1,024
Coarse to fine tokens	80/300 M	Non-causal	6x 1,024

Release date

April 2023

Broader Implications

We anticipate that this model's text to audio capabilities can be used to improve accessbility tools in a variety of languages.

While we hope that this release will enable users to express their creativity and build applications that are a force for good, we acknowledge that any text to audio model has the potential for dual use. While it is not straightforward 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, we also release a simple classifier to detect Bark-generated audio with high accuracy (see notebooks section of the main repository).
