New method speeds up audio LM temporal localization by 50x

Researchers have developed a new method called "internal frame-level reuse" for audio language models (LMs) that significantly speeds up temporal localization tasks. This approach bypasses the slow and error-prone process of generating timestamps as text tokens. Instead, it trains the audio LMs to directly use their internal frame-level representations for localization. The method has demonstrated over a 50x inference speedup and improved accuracy on tasks like word localization and speaker diarization, especially for audio with out-of-distribution durations. AI

IMPACT Accelerates inference for audio processing tasks, enabling more efficient real-time applications.

    Encode Once, Decode Never: Reusing Audio LM Internals for Efficient Temporal Localization

    arXiv:2602.10230v2 Announce Type: replace Abstract: Audio language models process input audio into rich frame-level representations, but the standard approach to temporal localization generates timestamps as sequences of text tokens, which discards the frame-level representations…
