TTS Wiki is a community-maintained knowledge base focused on documenting and comparing text-to-speech models and speech synthesis technologies. Its goal is to provide comprehensive, up-to-date information about a rapidly changing field, while noting that entries may not always be current and should be checked against official sources before production use. The site is a reference and learning resource rather than a provider of speech-generation products or commercial services.

For developers and other users, TTS Wiki offers installation and fine-tuning guides, licensing information, and comparisons of models by attributes such as supported languages, voice cloning, conversational features, fine-tuning options, release date, and license. Its catalog includes open-source systems such as VoxCPM, VibeVoice, Chatterbox, CosyVoice 2.0, and Tortoise TTS. Commercial services are listed as coming soon.

The wiki welcomes contributions, including new model listings, updated benchmarks, tutorials, audio samples, and corrections. It also emphasizes that voice cloning should be used only with proper consent and ethical care, and asks contributors not to upload copyrighted audio.
