Hey everyone,I’m building a voice booking assistant for Client's Company using VAPI, and I’m running into a bunch of strange behaviour that doesn’t line up with my prompt or tool logic. I’m hoping someone who has worked with complex VAPI assistants can help me diagnose what’s going on. I have attached the VAPI prompt to this post, I have deleted my client's company from the prompt so if there are any gaps in tool names or text that is why 🔥 Issues I'm Experiencing: 1. The assistant sometimes lags badly There are delays where the assistant just freezes for a second or two before responding. 2. It often says “I could not find that restaurant” even when the restaurant exists The ID lookup tool works perfectly when I test it directly, but inside VAPI the assistant frequently fails to pick up names and jumps straight to “could not find that restaurant”. It especially struggles with: - “Alla Bolognese” → hears it as something completely different - Restaurant names in general 3. The call audio breaks up / interrupts / talks over the user It keeps speaking before I have a chance to confirm details.It will: - Interrupt me mid-sentence - Repeat itself - Apologise multiple times even though nothing actually happened - Talk over the user during confirmations It feels like endpointing or turn-taking is misfiring. 4. Repeats itself and seems “stuck” sometimes At random points, it loops: - Apologising repeatedly - Repeating the same line - Re-explaining a step it already completed This doesn’t match the prompt at all. 5. Tone is inconsistent and sometimes shifts dramatically This one is wild: - It speaks in a normal tone - Pauses - Then suddenly shouts with excitement, like a different TTS voice style - Then goes back to normal It’s like ElevenLabs suddenly spikes in emotion even though stability is low and the prompt asks for calm, consistent tone. 6. Sometimes speaks in another language (!!) While repeating an email address, the assistant suddenly switched to an incomprehensible language for a sentence before coming back.

Hey everyone, I was hoping to ask you all for your advice: how do you make your voice agents handle taking email addresses from the user? My agents seem to be behaving funny and I wondered if you use a certain wording of your prompts or certain settings? Like how do you make sure they listen to the email correctly and not get any parts of the email wrong etc? I would appreciate any help you guys can give me

Hey guys, I am working on designing a demo for a meeting I have tomorrow with an owner of a hair loss clinic. The basic premise of the agent is to act as an assistant who helps new customers figure out the best treatment plan for them. I'm using retell ai and I'm just a little stuck on what is the best way to design it. I've attached a screenshot of what I have so far. Any helps you guys can give me will be really helpful thank you!
