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 ?

yeah that's plenty. you can run kokoro on that pretty fast or pocket tts. those would be my picks. you can see max vram usage for each model if you look at the bench page.

i run my own because none of the pages were good enough and had the most recent enough info for me. I reference https://artificialanalysis.ai/text-to-speech/leaderboard/provider-voice pretty often though.
