Pronunciation Scoring Loses a Pipeline Stage
OpenPA uses Whisper's attention to estimate word and utterance scores without forced alignment.
Summary
OpenPA uses Whisper's attention to estimate word and utterance scores without forced alignment.
OpenPA proposes a single pronunciation-assessment framework for both scripted and more open responses. It uses Whisper's cross-attention to predict word-level and utterance-level scores, avoiding a separate forced-alignment step. The authors report strong results on the tested closed and simulated open-response conditions, plus zero-shot evaluation on MultiPA. Those evaluations establish benchmark performance rather than a finished classroom service. The practical direction is simpler handling of mixed transcript conditions, a recurring obstacle when speech assessment moves beyond reading a fixed sentence.
