Abstract

The invention relates to a pitch correction scoring system and an implementation method thereof. The pitch correction scoring system comprises a sound acquisition module and a sound comparison module, wherein the sound acquisition module comprises a sound acquisition unit, a first filtering unit and a first write-in and storage unit, and the sound acquisition unit is used for acquiring sounds to be corrected; the sound comparison module comprises a second first write-in and storage unit, a first waveform reading unit, a second waveform reading unit, a standard audio acquisition unit, a second filtering unit, a waveform amplitude and frequency comparison unit and a result analysis and display unit, and the standard audio acquisition unit is used for acquiring standard audio. The pitch correction scoring system and the implementation method thereof have the advantages of being high in operability, easy to use, flexible, convenient to use, high in reusability, low in system cost, high in sampling precision and the like, can effectively improve pitch correction efficiency and accuracy of various musical instruments, and can be further extended to achieve voice recognition and evaluation.

Description

technical field [0001] The invention relates to the field of development and application of intelligent speech recognition technology and computer-aided system, in particular to an intonation correction scoring system and its realization method. Background technique [0002] In our daily life, we often encounter situations where the pitch of musical instruments is out of alignment. It is very difficult to adjust the pitch accurately without full experience. Therefore, how to adjust conveniently through the intonation reference becomes a difficult problem. On the surface, the intonation of a musical instrument lies in the tightness of the tuning, but at its core, the difference lies in the change in vibration frequency. If there is a convenient software for identifying and judging the frequency of musical instruments, then adjusting the pitch becomes intuitive and accurate. Contents of the invention [0003] In view of this, the object of the present invention is to prop...
