As part of transcribing recordings, Conversation Analyzer categorizes the textual contents of the transcript, by identifying key phrases based on the defined rules, and recording the subcategory or category those rules belong to. A category is a collection of subcategories, which in turn contain a series of rules. Each rule consists of a word or phrase and the party who said that word or phrase. If the transcript contains the word or phrase and was spoken by the specified party, Conversation Analyzer matches it against the category.
