New REDDIT Framework Corrects Timestamp Drift in ASR Models

Researchers have developed REDDIT, a novel post-training framework designed to fix timestamp inaccuracies in autoregressive Automatic Speech Recognition (ASR) systems. This method addresses timestamp drift, where the decoded time axis deviates from the actual audio, particularly over long non-speech segments. REDDIT employs a two-stage process that edits timestamp targets using the model's own replayed context and a frozen base distribution, while also incorporating a refinement stage. This approach successfully corrects timestamp drift without causing catastrophic forgetting of other ASR capabilities, as demonstrated on the Whisper-tiny model. AI

IMPACT This research offers a method to improve the accuracy of timestamping in ASR systems, potentially benefiting applications requiring precise temporal alignment.

    REDDIT: Correcting Model-Generated Timestamp Drift in ASR without Forgetting via Replay-Based Distribution Editing

    Modern autoregressive ASR systems can emit timestamps as decoded tokens, enabling timestamped transcription without frame-level aligners or inference-time post-processing. We show that these generated timestamps can drift across long non-speech spans: the transcript may remain pl…
