What

Twilio Conversational AI

Does

Twilio Conversational AI orchestrates a pipeline where incoming voice is transcribed using speech-to-text (STT), processed by a large language model (LLM) for intent and response generation, and then synthesized back to speech using text-to-speech (TTS). This enables real-time, natural conversations between users and AI-powered voice agents.

Developers typically build:

- Automated customer support agents

- Voice-enabled virtual assistants

- Appointment scheduling bots

- Outbound notification and reminder systems

- Voice-driven data collection tools

- Interactive voice response (IVR) systems
