We use this exact stack at work (OpenAI, ElevenLabs, Deepgram) for some exploratory use cases. The key issue we have now is latency with the LLM. Deepgram and Elevanlabs work brilliantly!
That live broadcast created a lot of buzz and numerous other use cases have popped up across the company. I'm working on a tech blog showcase next week to show it off on HN hopefully!
