Speech-to-Text on Personal Server

You can run Mozilla’s DeepSpeech engine either on a server in your home. You need to install the deepspeech engine itself:

.. _usage-docs:

Using a Pre-trained Model
=========================

Inference using a DeepSpeech pre-trained model can be done with a client/language binding package. We have four clients/language bindings in this repository, listed below, and also a few community-maintained clients/language bindings in other repositories, listed `further down in this README <#third-party-bindings>`_.

* :ref:`The C API <c-usage>`.
* :ref:`The Python package/language binding <py-usage>`
* :ref:`The Node.JS package/language binding <nodejs-usage>`
* :ref:`The command-line client <cli-usage>`
* :github:`The .NET client/language binding <native_client/dotnet/README.rst>`

.. _runtime-deps:

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.
* ``libstdc++`` - Standard C++ Library implementation. Some people have had to install this manually.

And finally configure your MyCroft.conf file:

I just did this recently but have to tell you, the accuracy is terrible on DeepSpeech at the moment, basically unusable. For me this is a combination of two things, my Australian accent, and a lack of modelling data for deepspeech. The former is here to stay but the latter will get better with time as more people contribute data to the project. If you’re in any kind of position to encourage others to contribute to the Mozilla Common Voice project, do so:
