Ask, Don't Guess: Targeted Clarification for Speech Recognition Errors

Speech recognition in real time in far-field conversational settings still incurs significant errors.

Key points

  • Identifying potential error spans during streaming ASR permits a recourse mechanism where the speaker can be asked to repeat the affected content under cleaner acoustic conditions.
  • We propose \sysname, a new framework for online error localization, that identifies spans likely to benefit from this intervention.
  • Our supervision uses clean audio to estimate how the recognizer's output might change under improved acoustic conditions.
  • We probabilistically align noisy and clean decodes using a pair-HMM to obtain soft supervision.
