We are working on a similar application and we have the same observation: external data is required to avoid hallucinations, especially if you go to less known places. It's absolutely the case with GPT-3.5 and often with GTP-4. We will release our new content in the next few days. We are finally wondering about eating the cost of expensive TTS or going with a cheap option for okay results. Can I ask which option you used for TTS?

Hello! I know of your guys work! I try to keep up with all the competitors :) Feel free to reach out to me rob @ summer dot ai and I'd be happy to talk shop.

For anyone else that is interested in this question: I've tried a whole bunch of the TTS services and found that Microsoft and AWS are the best of the standard providers IMHO and these are services that tend to have startup credits available so I use a mix of these two - I try to never rely on just one provider. I've met with the Eleven Labs folks and some of their demo's of the V2 stuff that's coming are really amazing but latency and pricing might rule them out as an option for the time being.

Thanks for the answer Rob, we just reached out :) We arrived to the same conclusion, we mostly rely on AWS Polly so far. Hopefully the pricing of better alternatives goes significantly down in the next months. We even tried to run different open source solutions but we could not find anything SOTA.
