deepspeech-rs

Rust bindings of Mozilla's DeepSpeech library.

The library is open source and performs Speech-To-Text completely offline. They provide pretrained models for English.

Quickstart

Preparation:

1. Obtain the Deepspeech native_client library. The release announcement contains precompiled libraries for various targets.
2. Download the pretrained models named like deepspeech-{version}-models.tar.gz from the release announcement and extract the zip file to some location.
3. Add the directory where the native_client library lies to your LD_LIBRARY_PATH and LIBRARY_PATH environment variables.

You can now invoke the example via:

cargo run --release --example client <path-to-model-dir> <path-to-audio-file>

It will print out the recognized sequence on stdout. The format of the audio files is important: only mono files are supported for now.

All codecs that the awesome audrey library supports are supported.

See DeepSpeech's release announcement for more.

Supported versions of DeepSpeech

We currently support version 0.9.0 of the DeepSpeech library. We will always try to provide compatibility with the most recent release possible.
