I will build a twilio ai voice agent for calls and appointment booking
Fulaji Thakor
About this gig
I build production-ready AI voice agents that answer inbound calls on Twilio, hold a natural conversation, and book appointments straight into your database - no human agent required.
The pipeline combines real-time speech-to-text, an LLM for conversation, and text-to-speech, with sub-second turn-taking so it feels like talking to a person. It checks availability, confirms the slot out loud, and only books after the caller clearly agrees. It also detects when the caller is wrapping up and ends the call cleanly instead of leaving dead air.
It supports multiple languages: it detects what language the caller is speaking mid-call and switches voice and responses automatically, covering English plus major Indian languages.
You also get an admin dashboard: a password-protected settings page to swap STT/TTS providers and API keys live without redeploying, keys encrypted at rest, plus a call cost dashboard showing LLM/STT/TTS/telephony spend per call.
Tech: Twilio Voice, Python, Pipecat, your choice of LLM/STT/TTS provider, MongoDB, React dashboard.
Great fit for clinics, salons, and service businesses that want a phone line booking appointments 24/7 without anyone picking up.
