Intonation evaluation method, intonation evaluation device and intonation evaluation system

Abstract

The embodiment of the invention provides an intonation evaluation method, an intonation evaluation device and an intonation evaluation system. The method comprises the following steps of: displaying the reference pitch value and singing vernier of a song on a screen; recording the real-time audio frequency of the song sung by a user and calculating the real-time pitch value of the real-time audio frequency; and judging whether the real-time pitch value of the real-time audio frequency is matched with the reference pitch value, if not, regulating relative position display relation of the singing vernier and the reference pitch value so as to remind the user in real time. By virtue of the implementation mode, the pitch and reference pitch matching accuracy of a singer is improved; and the implementation mode can be applied to various terminal entities, can be used in a cross-platform and cross-terminal mode and is wide in application range.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and more specifically, to a method, device and system for assessing intonation. Background technique [0002] In today's information age, various information devices have emerged as the times require: fixed telephones and mobile phones for voice transmission; servers and personal computers for information resource sharing and processing; TV sets, karaoke equipment, etc. These devices are produced to solve actual needs in specific fields. With the advent of the integration of electronic consumption, computer, and communication (3C), people are paying more and more attention to the research on the comprehensive utilization of information equipment in various fields, so as to make full use of existing resources and equipment to serve people. better service. [0003] The purpose of intonation is to make the pitch of singing and / or playing an instrument cons...

Problems solved by technology

[0005] However, in the prior art, timely reminders about the pitch matching situation cannot be sent to the singer, and the singer cannot adjust the singing voice in time according to the reminder, so the accuracy of the singer and the reference pitch matching is low

[0006] Moreover, in the prior art, the lyrics and pitch information are constantly moving in the horizontal direction so that the singer's line of sight needs to follow it when observing, which is not conducive to the singer's acquisition of pitch and lyrics information from the display interface.

At the same time, due to the limited screen width, it is difficult for the singer to see the lyrics of the next sentence, and even the lyrics of this sentence cannot be fully seen, so it is impossible to prepare in advance for unskilled songs.

In addition, the main body of the singing interface is the pitch and lyrics area. When the display is refreshed, due to the movement of the pitch and song areas, the entire information area needs to be refreshed continuously. Large-scale refreshes will take up more processor time, which is not conducive to Application of Tone System on Embedded Platform
