Multihash is a protocol for differentiating outputs from various well-established cryptographic hash functions, addressing size + encoding considerations.

Multibase is a protocol for disambiguating the encoding of base-encoded (e.g., base32, base36, base64, base58, etc.) binary appearing in text.

Multicodec is an agreed-upon codec table. It is designed for use in binary representations, such as keys or identifiers (i.e CID).

This package provides a set of JSON objects that implementers of JSON Schema validation libraries can use to test their validators.

It is meant to be language agnostic and should require only a JSON parser. The conversion of the JSON objects into tests within a specific language and test framework of choice is left to be done by the validator implementer.

This package provides a general reference and calibration data for spectroscopic data reduction (e.g. standard star spectra, atmospheric extinction curves, line lists for calibration lamps).

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

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

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.

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.

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.

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

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

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

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.

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.

This extension allows you to use Python 3 annotations for documenting acceptable argument types and return value types of functions.

This package provides a tool for authoring Sphinx themes with a simple (opinionated) workflow.

sphinx_gallery is a Sphinx extension that builds an HTML version from any set of Python scripts and puts it into an examples gallery.

Sphinxcontrib-newsfeed is an extension for adding a simple Blog, News or Announcements section to a Sphinx website.

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

A utility tool that provides several features that make it easy to translate and to apply translation to Sphinx generated document.

This package provide sphinx extension that automatically documents click applications.
