I'm assuming you're targeting this mainly at enterprises and business use-cases such as callcenters, but are you planning to make this usable for personal use cases as well? For example, having a bot to bounce ideas off while coding. Pretty much "just" the TTS / STT layer to talk to my finetuned LLM in a natural manner while you handle interruptions and such.

I think the main issue right now for personal use would be cost (and I'm guessing STT / TTS are the most expensive parts..)
