New RelayS2S architecture slashes dialogue system latency

By PulseAugur Editorial · [1 sources] ·

Researchers have developed RelayS2S, a novel dual-path architecture designed to reduce latency in real-time dialogue systems. This system uses a fast, speculative speech-to-speech (S2S) model to generate an immediate response prefix, while a slower, cascaded pipeline (ASR to LLM) generates a higher-quality continuation. A verifier component manages the transition between the two paths, ensuring a balance between speed and semantic accuracy. When integrated with models like GPT-4.1, RelayS2S significantly cuts down response latency while maintaining a high level of textual quality, making it a drop-in addition for existing cascaded systems. AI

IMPACT This architecture could significantly improve the user experience in real-time conversational AI applications by reducing response delays.

    RelayS2S: A Dual-Path Speculative Generation for Real-Time Dialogue

    arXiv:2603.23346v2 Announce Type: replace Abstract: Real-time spoken dialogue systems face a fundamental tension between latency and response quality. End-to-end speech-to-speech (S2S) models respond immediately and naturally handle turn-taking, backchanneling, and interruption, …
