A captioning evaluation system. The system accepts captioning data and determines a number of errors in the captioning data, as well as the number of words per minute across the entirety of an event corresponding to the captioning data and time intervals of the event. The errors may be used to determine the accuracy of the captioning and the words per minute, both for the entire event and the time intervals, used to determine a cadence and/or rhythm for the captioning. The accuracy and cadence may be used to score the captioning data and captioner.
