It's cool tech and I will give it a try. I will probably make a 8-bit-quant instead of the 4-bit which should be easy with the provided script.

That said, I found the example telling:

Input: “Can you guarantee that the replacement part will be shipped tomorrow?”:

Reponse with prompt: “I can’t promise a specific time, but we’ll do our best to get it out tomorrow. It’s one of the top priorities, so yes, we’ll try to get it done as soon as possible and ship it first thing in the morning.”

It's not surprising that people have little interest in talking to AI if they're being lied to.

PS: Is it just me or are we seing AI generated copy everywhere? I just hope the general talking style will not drift towards this style. I don't like it one bit.

This full duplex spoken thing, it's already for quite a long time being used by the big players when using the whatever "conversation mode" their apps offer, right? Those modes always seemed fast enough to for sure not be going through the STT->LLM->TTS pipeline?

Yes, OpenAI rolled out their advanced voice mode in September 2024. Since then it recognizes your emotions and tone of voice etc.

This is cool. It makes me want an unsloth quant though! A 7b local model with tool calling would be genuinely useful, although I understand this is not that.

UPDATE: I'd skip this for now - it does not allow any kind of interactive conversation - as I learned after downloading 5G of models - it's a proof of concept that takes a wav file in.

its really cool, but for real life use cases i think it lacks the ability to have a silent text stream output for example for json and other stuff so as its talking it can run commands for you. right now it can only listen and talk back which limits what u can make with this a lot

As a heavy user of MacWhisper (for dictation), I'm looking forward to better speech-to-text models. MacWhisper with Whisper Large v3 Turbo model works fine, but latency adds up quickly, especially if you use online LLMs for post-processing (and it really improves things a lot).
