13. A non-transitory computer-readable medium containing a speech-to-text program for causing a computer to execute: a speech recognition process for performing speech recognition of speech data and outputting a recognition result sub-word string as a sub-word string including time information based on a playback time of the speech data; a text editing process for creating edit result text which is text information written-out from the speech data; a sub-word conversion process for converting the edit result text into an edit result sub-word string; and a matching process for adding the time information to an edited part in the edit result text by collating the edit result sub-word string with the recognition result sub-word string to which the time information has been added according to consistency of sub-words to thereby match the edit result text and the speech data.
