ABSTRACT:
A device of the present invention obtains a character string of a speech recognition result and a confidence factor thereof. A time monitor monitors time and determines whether or not processing is delayed by checking the confidence factor and time status. When the processing is not delayed, a checker is asked to perform manual judgment. In this event, speech is processed and the manual judgment of the speech recognition result is performed on the basis of the processed speech. When the processing is delayed, automatic judgment is performed by use of the confidence factor. When the character string is judged to be correct as a result of the manual judgment or the automatic judgment, the character string is displayed as a confirmed character string. When the character string is judged to be incorrect, automatic correction is performed by matching on the basis of a next candidate obtained by the speech recognition, texts and attributes of the presentation, a script text, and the like. Character string after the automatic correction is displayed as an unconfirmed character string.
