PROBLEM TO BE SOLVED: To check the presence or the absence of deviation in rhythm regardless of a curriculum and to conduct a rhythm keeping training over a long time by discriminating the fact that rhythm is deviated when the difference between an estimated uttering timing and the timing of next uttering actually detected is deviated from a certain range. SOLUTION: A real time rhythm recognition section 14 recognizes the timing of uttering from the signals inputted from a voice input processing section 12 or the signals inputted from a music keyboard 13. A rhythm estimating section 15 recognizes rhythm from the timing of uttering recognized by the section 14 and estimates the timing of next uttering. A rhythm checking section 16 checks the deviation between the timing of uttering detected by the senction 14 and the timing of uttering estimated in the section 15. Then, a timing difference is fed back to the section 15. Moreover, the section 16 instructs a display device 17 to display a prescribed message when rhythm is deviated. |
