DeepSpeech is an open source Speech-To-Text engine, using a model trained by machine learning techniques based on [Baidu's Deep Speech research paper](https://arxiv.org/abs/1412.5567). Project DeepSpeech uses Google's [TensorFlow](https://www.tensorflow.org/) to make the implementation easier.
To install and use deepspeech all you have to do is:
```bash
# Create and activate a virtualenv
virtualenv -p python3 $HOME/tmp/deepspeech-venv/

Currently, only 16-bit, 16 kHz, mono-channel WAVE audio files are supported in the Python client. A package with some example audio files is available for download in our [release notes](https://github.com/mozilla/DeepSpeech/releases/latest).
Quicker inference can be performed using a supported NVIDIA GPU on Linux. See the [release notes](https://github.com/mozilla/DeepSpeech/releases) to find which GPUs are supported. To run `deepspeech` on a GPU, install the GPU specific package:

Running `deepspeech` might require some runtime dependencies to be already installed on your system:
Running `deepspeech` might, see below, require some runtime dependencies to be already installed on your system:
* sox - The Python and Node.JS clients use SoX to resample files to 16kHz.
* libgomp1 - libsox (statically linked into the clients) depends on OpenMP. Some people have had to install this manually.
