MICASE Manual

Statistical Overview of Speakers and Speech Events

The four tables provided here give descriptive frequency figures for MICASE, showing the composition of the corpus by speaker and speech event categories. These word counts are for the untagged version of MICASE, and ‘words' were defined as strings bounded by spaces or punctuation; hyphenated words (e.g., eighty-five, cross-sectional, non-native) and words with apostrophes (e.g., she'll, shouldn't've, don't, John's) counted as one word.
