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
