Facebook AI Research's Automatic Speech Recognition Toolkit

What it solves

wav2letter++ is designed to provide a high-performance framework for end-to-end automatic speech recognition (ASR), enabling the reproduction of various research papers and the use of pre-trained models for converting speech to text.

How it works

The project provides a set of recipes and pre-trained models that integrate with the Flashlight machine learning library. It supports various ASR architectures, including streaming ConvNets, sequence-to-sequence models with time-depth separable convolutions, and lexicon-free speech recognition.

Who it’s for

It is primarily intended for researchers and developers working on speech recognition, specifically those looking to reproduce academic results or implement state-of-the-art ASR architectures.

Highlights

  • Supports multiple research-backed ASR architectures including ConvNets and Seq2Seq.
  • Provides recipes for semi-supervised learning and self-training for speech recognition.
  • Includes pre-trained models for immediate use.
  • Integrated with the Flashlight library for high-performance execution.
