FAQ
Which AI voice platforms do you specialize in?
I specialize in setting up advanced AI voice agents using Retell AI. For natural, human-like voice synthesis, I integrate platforms like Eleven Labs or Play.ht.
How does the appointment booking system work?
I integrate Retell AI directly with your Cal.com account. During the call, the AI agent will check your live availability, ask the buyer for a time slot, and instantly book the meeting into your calendar.
Do I need to provide my own Retell AI and Cal.com accounts?
Yes, you will need to provide your API keys and login details for Retell AI, Cal.com, and Twilio. If you don't have them yet, don't worry—I will guide you step-by-step through the setup.
Can the Retell AI agent handle complex call flows?
Yes! I can program the agent to follow specific custom scripts, answer detailed business FAQs, qualify leads, and even transfer the call to a real human agent if needed.
Can the Retell AI voice agent speak multiple languages?
Yes! Retell AI supports 31+ languages including Spanish, French, German, Hindi, and Arabic. It features smart auto-language detection, allowing the agent to seamlessly understand and switch languages mid-conversation based on the caller's preference.
What happens if the customer interrupts the AI agent while speaking?
Retell AI has built-in smart interruption handling. If a customer starts speaking mid-sentence, the AI agent will instantly stop, listen to the customer, and respond accordingly, just like a real human.
Do you provide the script and call flow logic for Retell AI?
I will help you optimize your existing script for AI behavior. However, if you need a completely new script and complex call flow designed from scratch, please message me for a custom offer.
Will I be able to see the call transcripts and recordings?
Yes, absolutely! Every single call handled by the agent will be recorded, and you can view the audio files along with accurate text transcripts directly inside your Retell AI dashboard.
