Improving error prediction in spoken dialog systems

摘要

A spoken dialog system configured to use a combined confidence score. A first confidence score, indicating a confidence level in a speech recognition result of recognizing an utterance, is provided. A second confidence level, indicating a confidence level of mapping the speech recognition result to an intent, is provided. The first confidence score and the second confidence score are combined to form a combined confidence score. A determination is made, with respect to whether to accept the intent, based on the combined confidence score.
