General

This is the initial release of Deep Speech, an open speech-to-text engine. This release includes source code

v0.1.0.tar.gz

and a model, not yet optimized for size,

deepspeech-0.1.0-models.tar.gz

trained on American English which achieves a 6.0% word error rate (The language model included some test data.) on the LibriSpeech clean test corpus, and example audio

audio-0.1.0.tar.gz

which can be used to test the engine.

Bindings

In addition it includes a Python based command line tool deepspeech, installed through

pip install deepspeech

Alternatively, quicker inference can be performed using a supported NVIDIA GPU on Linux. (See below to find which GPU's are supported.) This is done by instead installing the GPU specific package:

pip install deepspeech-gpu

Also, it exposes bindings for the following languages

  • Python (Versions 2.7, 3.4, 3.5, and 3.6) installed via
    pip install deepspeech
    Alternatively, quicker inference can be performed using a supported NVIDIA GPU on Linux. (See below to find which GPU's are supported.) This is done by instead installing the GPU specific package:

  • NodeJS (Versions 4.x, 5.x, and 6.x) installed via
    npm install deepspeech

  • C++ which requires the appropriate shared objects are installed from native_client.tar.xz (See the section in the main README which describes native_client.tar.xz installation.)

In addition there are third party bindings that are supported by external developers, for example

  • Rust which is installed by following the instructions on the external Rust repo.

Supported Platforms

  • OS X 10.12 and 10.13
  • Linux x86 64 bit with a modern CPU (Supports up to AVX2/FMA)
  • Linux x86 64 bit with a modern CPU + NVIDIA GPU (Compute Capability at least 3.0, see NVIDIA docs)
  • Raspbian Jessie on Raspberry Pi 3
