Retell AI
#1 AI Voice Agent Platform for Automating Calls

Retell AI is a platform for building, testing, deploying, and monitoring AI-powered voice agents that can handle phone calls at scale. It uses low-latency speech recognition, large language models, and text-to-speech to conduct natural conversations and perform real-time actions like booking appointments or updating records. The platform targets businesses looking to automate inbound and outbound call center operations without changing their existing telephony infrastructure.
Retell AI orchestrates speech recognition, LLM-powered conversation understanding, and text-to-speech with ~600ms latency, enabling AI agents to handle calls, execute real-time functions, and integrate with existing telephony via SIP trunking.
