Vocalization scoring method

Abstract

The invention discloses a vocalization scoring method, including the following steps: 1) according to beats of a song, dividing notes of a vocalization into N sections arranged according to time sequence, each section including notes in different numbers, each note being corresponding to a standard pitch value; 2) recording voice data, according to beats of the song, dividing the voice data into Nsections arranged according to time sequence, dividing data in each section into n sampling points whose duration is dj, analyzing the sampling points, to obtain pitch values p of the sampling points; 3) using the following formula to score the pitch values p of the sampling points; 4) counting score of the voice data. The vocalization scoring method is simple and convenient, and scoring efficiency is higher. The voice data is divided into N sections arranged according to time sequence, and each section is scored, so an obtained scoring result is fine and accurate.

Description

technical field

[0001] The invention relates to a voice training scoring method. Background technique

[0002] There is no scoring method for voice training in the prior art, and the score of voice training is evaluated only based on the teacher's personal experience, resulting in inconsistent scoring standards. There is also a relatively common scoring system for karaoke, which calculates the difference between some simple physical characteristics between the singer's singing and the original sound in the database (or data that can be regarded as the original sound), such as comparing singing signals The distance between the target signal sampling points, the distance between the sound level curves, and the distance between the fundamental frequency sequences are compared, and these differences are used as evaluation criteria.

[0003] This scoring system is only compared on the level of simple physical characteristics. When the user's singing and the original sound in the...
