We propose a novel approach for addressing automatic speech recognition (ASR) and natural language understanding (NLU) errors in an interactive spoken dialog system using targeted clarification (TC). TC applies when a spoken utterance is partially recognized by focusing a clarification question on the misrecognized part of the utterance. A key component of TC is accurate detection of localized ASR and NLU errors in an utterance. In this work, we develop statistical models of presence and correctness for domain concepts within an ASR/NLU result and use these to drive a targeted clarification (TC) strategy. We evaluate the accuracy of the models and their effect on the dialog strategy in an interactive multimodal assistant. |
