TTSengine

TTSengine is a text-to-speech synthesis engine designed to convert written text into spoken language. It provides a modular framework for building and deploying speech synthesis systems and supports multiple languages, voices, and speaking styles.

A typical TTSengine architecture includes a text front end for normalization and tokenization, optional linguistic analysis or grapheme-to-phoneme conversion, a prosody model, and a waveform generator such as a vocoder. It may support concatenative, parametric, and neural synthesis methods, and often implements SSML compatibility to control pronunciation, prosody, and pacing. Components can be extended or replaced via plug-ins or API integrations.

Common use cases include assistive technologies, screen readers, virtual assistants, e-learning tools, and embedded devices. TTSengine can run in cloud environments, on desktop or mobile platforms, and in on-device configurations where latency and privacy are critical.

The project ecosystem varies by deployment. Open-source and commercial variants exist, with licenses ranging from permissive to copyleft. Ongoing development focuses on improving naturalness, multi-language coverage, and voice customization, including speaker adaptation and emotion modeling.
