Abstract:
A method for verifying a speech recognition result comprises: randomly selecting user response speech data generated based on a preset conversation script in a given application scenario; dividing a user speech segment in the user response speech data into multiple speech sub-segments of a preset time length; extracting acoustic features from the respective speech sub-segments, and acquiring emotion tags for the respective speech sub-segments according to the acoustic features; linearly joining the emotion tags and the user response speech data, and adding speech sub-segment identifiers; and comparing speech recognition results corresponding to the respective speech sub-segments against standard speech recognition results, and calculating the percentage of speech sub-segments having matching speech recognition results. The invention can efficiently and accurately verify the accuracy of a speech recognition result in a selected application scenario.
