i noticed thath didnt introduce myself, We’re Scintia, an AI startup based in Lyon (France) We build intelligent voice agents to handle calls (reservations, transfers, outbound sales, support). And honestly, Vapi is at the core of our project, it’s what allows us to deliver fluid, natural, low-latency conversations. We want to push Vapi to the max, because without it, our vision wouldn’t be possible.

Great to connect — I’m an AI Engineer based in the US, currently working with Vapi to build advanced voice agents. My work also spans: Computer Vision ,Chatbots & LLMs ,Robotics & Edge Devices Excited to see how far you can push Vapi — it’s an incredible foundation
s
That’s great to hear 🙌 One of our key challenges is that everything must work 100% in French (STT, TTS, latency, natural tone). It’s not always easy to get the same level of accuracy and fluidity as in English. On top of that, we need to ensure scalability, smooth human transfer, and instant call handling for multiple clients. Would love to exchange on best practices, your experience could really help us push Vapi further
d
Absolutely, I’d love that too — exchanging best practices and experiences around Vapi would be really valuable.
Scintia Did you get any french voice that looks natural not robotic?
s
Yes, voice quality is important too, we’ve tested providers like Cartesia, ElevenLabs, etc., and some French voices are actually pretty good. But honestly, our biggest challenge is latency and crafting the most efficient prompt in French. Even with a nice voice, if there’s delay or the prompt isn’t well optimized, the conversation doesn’t feel natural anymore.
d
You are completely true. On phone call their latency is too high.
we cannot use Vapi Number because its not available in france, only in US
d
Yes, you’re absolutely right, and that’s a really great idea you have
