Unique: Extracts timestamps directly from the transformer's attention mechanism and frame-to-token alignment during decoding, avoiding the need for external forced-alignment tools (e.g., Montreal Forced Aligner). Operates end-to-end within the speech recognition pipeline with no additional model inference.

vs others: Faster than post-hoc alignment tools because timestamps are computed during transcription; however, less accurate (±100-200ms) than dedicated forced-alignment models trained specifically for alignment, which can achieve ±50ms precision.
