1303: Transcription - Utterance Segmentation

Communication unit (C-unit) segmentation is used for segmenting the transcripts in the SALT reference databases. Language samples which are compared to samples selected from these databases should also be segmented into C-units. By using C-units, language sample transcripts have consistent segmentation that is rule-governed. In this course, you will become familiar with C-units and learn how to segment utterances into C-units using the interactive modules, "Try It" and "Self Check".
