AI Technology Market: PolyAI Launches Audio-Native Voice AI Model Dialog-RSN-1
PolyAI introduced Dialog-RSN-1, an audio-native dialog model for enterprise voice agents. The model fuses speech recognition, turn-taking, function calling, and response generation into a single large language model that reasons directly over raw call audio. Output is handled by a separate text-to-speech system to maintain control over the caller-experienced voice. PolyAI claims sub-300ms latency in production, positioning the model against cascaded architectures and speech-to-speech models like GPT Realtime and Gemini Live. The initial release supports English only, with broader language support planned. The announcement follows an $86 million Series D closed in December 2025.
PolyAI, a leading enterprise voice AI startup, introduces a novel audio-native model that could improve latency and emotional awareness in customer service voice agents, with relevance for AI-driven CX and marketing automation.
