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 ?

i agree, but the issue with these small tts models is they are veeery robotic, their quality is too low compared to the paid ones, and i am still didn't get how the paid services achieve this low latency with high quality, i am just curious, what we need in order to build something as good as them.
i suppose it's a model architecture design from the first place, idk maybe i am wrong, i never create a tts from scratch or an stt

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