Rate of Speech

Rate of speech is simply a measure of words spoken per given unit of time. We measure this in words spoken per minute. However, for convenience, we are also outputting as a variable simply the length of the file that was analyzed and hence multiplying nlp_wordsPerMin_mean by nlp_totalTime_mean will give the total number of words spoken.

Please note that the latter measurement is in seconds, so one would have to divide it by 60 first :)

Derived Variables

nlp_wordsPerMin_mean	Rate of speech, in average number of words spoken per minute.
