This package provides a Gstreamer plugin for the VOSK voice recognition engine.

Festival offers a general framework for building speech synthesis systems as well as including examples of various modules. As a whole it offers full text to speech through a number APIs: from shell level, though a Scheme command interpreter, as a C++ library, from Java, and an Emacs interface. Festival is multi-lingual though English is the most advanced. The system is written in C++ and uses the Edinburgh Speech Tools Library for low level architecture and has a Scheme (SIOD) based command interpreter for control.

eSpeak NG is a software speech synthesizer for more than 100 languages. It is based on the eSpeak engine and supports spectral and Klatt formant synthesis, and the ability to use MBROLA voices.

PocketSphinx is one of Carnegie Mellon University's large vocabulary, speaker-independent continuous speech recognition engine.

The Speech Dispatcher project provides a high-level device independent layer for access to speech synthesis through a simple, stable and well documented interface.

Sonic implements a simple algorithm for speeding up or slowing down speech. However, it's optimized for speed ups of over 2X, unlike previous algorithms for changing speech rate. Sonic is a C library designed to be easily integrated into streaming voice applications such as text-to-speech (TTS) back ends.

The primary motivation behind Sonic is to enable the blind and visually impaired to improve their productivity with speech engines, like eSpeak. Sonic can also be used by the sighted.

Flite (festival-lite) is a small, fast run-time text to speech synthesis engine developed at CMU and primarily designed for small embedded machines and/or large servers. It is designed as an alternative text to speech synthesis engine to Festival for voices built using the FestVox suite of voice building tools.

eSpeak is a software speech synthesizer for English and other languages. eSpeak uses a "formant synthesis" method. This allows many languages to be provided in a small size. The speech is clear, and can be used at high speeds, but is not as natural or smooth as larger synthesizers which are based on human speech recordings.

Ehko is a TTS software. It supports Cantonese, Mandarin, Toisanese, Zhaoan Hakka, Tibetan, Ngangien and Korean (in trial). It can also speak English through eSpeak or Festival.

The MIT Language Modeling (MITLM) toolkit is a set of tools designed for the efficient estimation of statistical n-gram language models involving iterative parameter estimation. It achieves much of its efficiency through the use of a compact vector representation of n-grams.

ONNX ASR is a Python library for automatic speech recognition using ONNX Runtime. It supports models including Whisper and NeMo Parakeet. Includes bundled Parakeet TDT V3 model weights (int8, CC-BY-4.0, NVIDIA).

Pocket TTS is a fast neural text-to-speech engine with ~100M parameters, running at approximately 6x realtime on CPU. English only.

This package enables developers to author ONNX models using a Python-based domain-specific language.

sphinxcontrib-jsmath is a Sphinx extension which renders display math in HTML via JavaScript.

This package provides a Sphinx extension for linking to a project's issue tracker. This includes roles for linking to issues, pull requests and user profiles. Support for GitHub is built-in, but other services can also be supported with sphinx-issues.

This package provides a Bootstrap-based Sphinx theme from the PyData community.

This package is an extension to reStructuredText and Sphinx to be able to read and render the Doxygen xml output.

python-nbsphinx is a Sphinx extension that provides a source parser for *.ipynb files. Custom Sphinx directives are used to show Jupyter Notebook code cells (and of course their results) in both HTML and LaTeX output. Un-evaluated notebooks - i.e. notebooks without stored output cells - will be automatically executed during the Sphinx build process.

sphinxcontrib-htmlhelp is a Sphinx extension which renders HTML help files.

Doxylink is a Sphinx extension to link to external Doxygen API documentation. It allows you to specify C++ symbols and it will convert them into links to the HTML page of their Doxygen documentation.

Create a Sphinx documentation shell for your project and include the README file as the documentation index. It handles extracting the required meta data such as the project name, author and version from your project for use in your Sphinx docs.

This package provides a Sphinx extension to create tags for documentation pages.

Create tabbed content in Sphinx documentation when building HTML.

This package provides guzzle_sphinx_theme, a theme for the Sphinx documentation system, used by Guzzle and several other projects.
