PolyAI

PolyAI is a conversational voice AI platform enabling enterprises to replace or supplement human phone agents with AI that sounds natural, understands different accents, and handles full customer conversations from start to finish. Founded in 2017 by researchers from the University of Cambridge, PolyAI offers ultra-low latency conversational AI, lifelike text-to-speech, and barge-in handling for real human conversations. The proprietary speech-recognition system can swap between domain-specific vocabularies mid-conversation. PolyAI has built and deployed AI agents for many enterprise brands including Marriott, Volkswagen, PG&E, Caesars, and MetroBank. Voice assistants handle over 50% of customer inquiries including authentication, order management, billing, and reservations. Agent Studio is the voice-first omnichannel platform for conversational AI with API (ADK) for native IDE integration.
