Karaoke scoring method based on voice matching, and device thereof

Abstract

The invention provides a karaoke scoring method based on voice matching. In a singing process, an audio frequency of an original singer is extracted. Simultaneously sound of a user is continuously extracted, and an audio characteristic of the user is calculated. Furthermore the audio characteristic of the user is compared with the audio characteristic of the original singer sentence by sentence. Scoring is performed according to different weights. According to the karaoke scoring method, factors of tone, tone quality, volume, rhythm, time length, etc. are not considered; and sound essence is considered. The essential characteristic of the sound is considered. The spectral characteristic of the sound is analyzed. The factors can be comprehensively considered, and a corresponding calculating is performed, thereby obtaining a more comprehensive and more accurate scoring result.

Description

technical field [0001] The present application relates to a karaoke scoring method and device, in particular to a karaoke scoring method and device based on voice matching. Background technique [0002] KTV singing practice scoring is a function that appeared very early, but most of the scoring schemes adopted are relatively simple, such as simply comparing the volume. If the volume is high, the score is high, and if the volume is low, the score is low. The user experience is very bad, or the volume can be directly compared, that is, the volume input by the user is compared with the volume of the original audio. The closer the volume is, the higher the score. [0003] The reason why scoring is difficult is that there are various standards for judging the quality of singing, whether the timing of singing is aligned, whether the pitch of singing is sufficient, whether the timbre of singing is consistent, etc. All these factors must be considered comprehensively. That is to sa...

Problems solved by technology

However, there are many factors, it is difficult to consider them comprehensively, and it is also difficult to consider them comprehensively. There are many controversies about which factor should account for a larger proportion and which factor should account for a smaller proportion. At present, many people have proposed There are many scoring methods, including pitch, rhythm duration, etc., but due to the above-mentioned many specific factors, the standard is difficult to unify, so there is no method and system that can comprehensively consider various factors, and at the same time be able to achieve more accurate scoring
