What it does
SpeechBrain is an open-source toolkit for building speech and language technology, built on PyTorch. It covers speech recognition, recognising who is speaking, cleaning up noisy audio, separating voices and more.
It comes with over a hundred ready-trained models and many training recipes, so researchers can reuse or fine-tune existing work. Its makers say transcribing a file takes only a few lines of code.
It also has many tutorials and is used in teaching at several universities.
Who it's for
Researchers, students and developers working on speech technology.
