Abstract

Systems and methods are provided for scoring a speech sample. Automatic speech recognition is performed on the speech sample using an automatic speech recognition system to generate a transcription of the sample. Words in the transcription are associated with parts of speech, and part of speech sequences are extracted from the parts of speech associations. A grammar metric is generated based on the part of speech sequences, and the speech sample is scored based on the grammar metric.
