Contact

We prefer to have discussions directly on Github issue page, so that all the information is transparent to all the contributors and is auto-archived on the Github. If you wish to use email, please contact:

Please refer to the legacy citation of S3PRL and the timeline below, which justify our initiative on this project. This information is used to protect us from half-truths. We encourage to cite the individual papers most related to the function you are using to give fair credit to the developer of the function. You can find the names in the Change Log. Finally, we would like to thank our advisor, Prof. Hung-yi Lee, for his advice. The project would be impossible without his support.

If you have any question (e.g., about who came up with / developed which ideas / functions or how the project started), feel free to engage in an open and responsible conversation on the GitHub issue page, and we'll be happy to help!

Contribution (pull request)

Guideline

  • Starting in 2024, we will only accept new contributions in the form of new upstream models, so we can save bandwidth for developing new techniques (which will not be in S3PRL.)
  • S3PRL has transitioned into pure maintenance mode, ensuring the long-term maintenance of all existing functions.
  • Reporting bugs or the PR fixing the bugs is always welcome! Thanks!

Introduction and Usages

This is an open source toolkit called s3prl, which stands for Self-Supervised Speech Pre-training and Representation Learning. Self-supervised speech pre-trained models are called upstream in this toolkit, and are utilized in various downstream tasks.

The toolkit has three major usages:

Pretrain

  • Pretrain upstream models, including Mockingjay, Audio ALBERT and TERA.
  • Document: pretrain/README.md

Upstream

  • Easily load most of the existing upstream models with pretrained weights in a unified I/O interface.
  • Pretrained models are registered through torch.hub, which means you can use these models in your own project by one-line plug-and-play without depending on this toolkit's coding style.
  • Document: upstream/README.md

Downstream


Here is a high-level illustration of how S3PRL might help you. We support to leverage numerous SSL representations on numerous speech processing tasks in our GitHub codebase:

interface


We also modularize all the SSL models into a standalone PyPi package so that you can easily install it and use it without depending on our entire codebase. The following shows a simple example and you can find more details in our documentation.

  1. Install the S3PRL package:
pip install s3prl
  1. Use it to extract representations for your own audio:
import torch
from s3prl.nn import S3PRLUpstream

model = S3PRLUpstream("hubert")
model.eval()

with torch.no_grad():
    wavs = torch.randn(2, 16000 * 2)
    wavs_len = torch.LongTensor([16000 * 1, 16000 * 2])
    all_hs, all_hs_len = model(wavs, wavs_len)

for hs, hs_len in zip(all_hs, all_hs_len):
    assert isinstance(hs, torch.FloatTensor)
    assert isinstance(hs_len, torch.LongTensor)

    batch_size, max_seq_len, hidden_size = hs.shape
    assert hs_len.dim() == 1

With this modularization, we have achieved close integration with the general speech processing toolkit ESPNet, enabling the use of SSL models for a broader range of speech processing tasks and corpora to achieve state-of-the-art (SOTA) results (kudos to the ESPNet Team):

You can start the journey of SSL with the following entry points:


Feel free to use or modify our toolkit in your research. Here is a list of papers using our toolkit. Any question, bug report or improvement suggestion is welcome through opening up a new issue.

If you find this toolkit helpful to your research, please do consider citing our papers, thanks!

Installation

  1. Python >= 3.6
  2. Install sox on your OS
  3. Install s3prl: Read doc or pip install -e ".[all]"
  4. (Optional) Some upstream models require special dependencies. If you encounter error with a specific upstream model, you can look into the README.md under each upstream folder. E.g., upstream/pase/README.md=
