I got a bonus question... Is there a good end-to-end voice conversation solution? I'd like to try something which directly processes the audio and returns audio, rather than the whole pipeline with vad -> stt -> llm -> tts

Rules:
Rule 1 - No harassment or personal character attacks of community members. I.E no namecalling, no generalizing entire groups of people that make up our community, no baseless personal insults.
Rule 2 - No comparing artificial intelligence/machine learning models to cryptocurrency. I.E no comparing the usefulness of models to that of NFTs, no comparing the resource usage required to train a model is anything close to maintaining a blockchain/ mining for crypto, no implying its just a fad/bubble that will leave people with nothing of value when it burst.
Rule 3 - No comparing artificial intelligence/machine learning to simple text prediction algorithms. I.E statements such as "llms are basically just simple text predictions like what your phone keyboard autocorrect uses, and they're still using the same algorithms since <over 10 years ago>.
Rule 4 - No implying that models are devoid of purpose or potential for enriching peoples lives.
There are not many models that support any-to-any, currently the best seems to be Qwen3-Omni, the audio quality is not great and it is not supported by llama.cpp: https://github.com/ggml-org/llama.cpp/issues/16186
Thanks! if anyone has more (good) alternatives or something like a curated list, I'd have a look at that as well... always a bit complicated to stay up to date and go through the myriad of options myself...
Kobold.CPP has pretty good TTS model integration I used OuteTTS model when I played around with it but theres also API integration with commercial ones like kokoro.
However, I'm no sure if its able to stream to a TTS model as the llm is generating when I tried it just waited till after output to send to voice model you may need to do some documentation reading to see if real time streaming is possible if you go that route.
Alpaca on Flathub seems ok
OpenWebUI has TTS and STT.
