Gnuspeech

Gnuspeech is a free software project aiming to develop a speech synthesis system. It is part of the GNU Project and is intended to provide a complete text-to-speech (TTS) solution under a free software license. Gnuspeech aims to be highly customizable and adaptable to different languages and speaking styles. Its development relies on contributions from volunteer programmers and linguists.

The primary goal of Gnuspeech is to create a TTS system that can be freely used and modified, avoiding proprietary restrictions that are often associated with commercial speech synthesis software. This allows for greater accessibility and wider distribution of the technology.

The system is typically structured into modules handling various aspects of the TTS process, including text normalization, phonetic transcription, prosody generation, and waveform synthesis.
