# wav2letter++

wav2letter++ is a fast open source speech processing toolkit from the Speech Team at Facebook AI Research.
It is written entirely in C++ and uses the [ArrayFire](https://github.com/arrayfire/arrayfire) tensor library and the [flashlight](https://github.com/facebookresearch/flashlight) machine learning library for maximum efficiency.
Our approach is detailed in this [arXiv paper](https://arxiv.org/abs/1812.07625).

The goal of this software is to facilitate research in end-to-end models for speech recognition.

The previous version of wav2letter (written in Lua) can be found in the "wav2letter-lua" branch under the repository.
