New X2Streaming-ASR system slashes speech recognition latency

By PulseAugur Editorial · [1 sources] ·

Researchers have developed X2Streaming-ASR, a novel system for streaming automatic speech recognition (ASR) designed for real-time applications. Unlike existing methods that use fixed chunk sizes or target delays, X2Streaming-ASR optimizes when to commit partial transcripts and what context to use. This three-stage training approach significantly reduces commit latency, achieving as low as 27-84 ms on benchmark datasets like AISHELL-1/2/3 and WenetSpeech, while also improving character error rate compared to baseline systems. AI

IMPACT This new approach to streaming ASR could enable more responsive and accurate real-time voice agents and dialogue systems.

    X2Streaming-ASR: wait when uncertain, emit when ready for streaming ASR

    arXiv:2609.08672v1 Announce Type: cross Abstract: Streaming automatic speech recognition (ASR) for real-time voice agents and full-duplex dialogue must provide accurate partial transcripts with low commit latency. Existing systems commonly use a fixed chunk size, look-ahead, or t…
