Notice for pull requests

Please note that if you did not explicitly discuss with Andy and Leo (the owners of the repository) about your planning development, by default it will not be merged into S3PRL and is better to be maintained in your own repository. Please see our pull request policy. Thanks for your understanding!

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

• Utilize upstream models in lots of downstream tasks
• Benchmark upstream models with SUPERB Benchmark
• Document: downstream/README.md

Below is an intuitive illustration on how this toolkit may help you:



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
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

Development pattern for contributors

1. Create a personal fork of the main S3PRL repository in GitHub.
2. Make your changes in a named branch different from master, e.g. you create a branch new-awesome-feature.
3. Contact us if you have any questions during development.
4. Generate a pull request through the Web interface of GitHub.
5. Please verify that your code is free of basic mistakes, we appreciate any contribution!
