7. A speech recognition system comprising:
-
a speech recognizer for translating speech into text, said text being one or more sentences, said speech recognizer comprising a confidence level scorer for assigning one of a user selected number possible scores for each word of said one or more sentences; a user interface for displaying said text based on said scores, wherein said scores cause said each word to be displayed in accordance with one of a user selected number of indications, each of said indications indicating into which of a selected number of sub-ranges said scores fall; and a user control which allows a user of said speech recognition system to select said number of sub-ranges and boundaries of each sub-range. - View Dependent Claims (8, 9, 10, 11)
