Abstract

The present invention relates to what causes a computer to read a voice recognition program from a first recording medium, and read voice data from a second recording medium, and causes a CPU in the computer to recognize voice represented by the read voice data according to the voice recognition program, convert the result of voice recognition into text data, and display the converted text data on a display unit.

Also included is a check mark button used by a speaker to designate a portion of voice data, which is input through a microphone, corresponding to an unnecessary word or the like. The portion of the voice data in which a check mark is inscribed is not regarded as an object of voice recognition. Only the other portion of the voice data in which the check mark is not inscribed is regarded as an object of voice recognition, and voice recognition is thus carried out.

Furthermore, the sound level of a voiceful portion of voice data is rated. The gain of the voice data is adjusted according to the rated level. On the basis of the voice data whose sound level has been adjusted, voice recognition is carried out.
