Open catalog of 168 TTS and 106 STT systems for local voice builders

[AiD3veloper]

While building Imprynt, I spent roughly a year collecting information about the speech systems that could fit a local, privacy-conscious voice product. The research became large enough that keeping it private seemed wasteful, so I published it as OpenGauntlet.

The two directories that may be most useful to OpenVoiceOS builders are:

• 168 text-to-speech systems: https://opengauntlet.com/tts.html
• 106 speech-to-text systems: https://opengauntlet.com/asr.html

The catalog includes local and hosted systems, hardware requirements, licensing, language and capability information, lifecycle status, source links, and published benchmark data where available. These are sourced research directories, not claims that I benchmarked all 274 systems myself.

I would genuinely appreciate corrections, missing engines, outdated lifecycle information, or suggestions for fields that would make the directories more useful for local/offline voice-assistant work. There are correction and model-request links on the site, or feedback can be left here.
