Join our official Discourse to discuss with SpeechBrain users coming from all around the world!

Community driven

SpeechBrain has been designed to help researchers and developers. The future of SpeechBrain highly depends on this community engagement. Anyone can clone the code, develop new functionalities, raise issues, or create a new discussion. With SpeechBrain we hope to start a symbiotic relationship between the toolkit and the research community.

Contributing to SpeechBrain

Contributions can take various forms (see our dedicated page):
1. Researchers can propose and implement new functionalities through pull requests. To ensure high-quality standards, each new pull request will be reviewed by a core team member.
2. Sponsors can contribute financially or with human resources by contacting us via email.

SpeechBrain needs you in order to evolve!
