Speech recognition with text generation from portions of voice data preselected by manual-input commands

A computer reads a voice speech recognition program from a first recording medium, and reads voice data from a second recording medium, and causes a CPU in the computer to recognize speech represented by the read voice data according to the speech recognition program, convert the result of speech recognition into text data, and display the converted text data on a display unit. A check mark button used by a speaker designates 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 speech recognition. Only the other portion of voice data in which the check mark is not inscribed is regarded as an object of speech recognition, and speech recognition is thus carried out. Furthermore, the sound level of a voice 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, speech recognition is carried out.
