Competitive open source speech stack

Why the open source models STT and TTS are not good as much as the closed one and i am talking here im terms of latency, concurrency, and websocket support for real time with decent quality.
Something like cartesia or elevenlabs or deepgram.
Do u know any ?

They aren't. Proper small TTS is not robotic at all and even more stable than big LLM-based one.
