NATURAL LANGUAGE GRAMMAR IMPROVEMENT

A method for configuring natural language grammars is provided to include identifying a first transcription having a first automatic speech recognition (ASR) score and a first natural language understanding (NLU) score and identifying a second transcription having a second ASR score and a second NLU score. The method includes detecting that a difference between the first and second ASR scores has a signed value with an opposite sign than a sign of a signed value of a difference between the first and second NLU scores, and responsive to detecting the opposite sign providing, to an evaluator, the audio query and the first and second transcriptions, receiving, from the evaluator, an indication of which of the first and second transcriptions is a correct transcription, and adjusting a value implemented to calculate the first NLU score or a value implemented to calculate the second NLU score.
