Problems solved by technology

[0003] The intelligent scoring system in existing language learning machines generally only uses simple VAD technology, and the scoring is often very inaccurate, similar to the scoring system in karaoke machines
The high-end intelligent scoring system generally uses speech recognition technology, but the implementation complexity is relatively high, and it can only give a general evaluation, such as "very good, good, average, poor", and cannot evaluate the user's pronunciation problems. detailed analysis
[0004] To sum up, the intelligent scoring system in the existing language learning machine cannot conduct detailed analysis of the user's speech rate, rereading, pronunciation, etc., resulting in the detection of the user's voice is not accurate, meticulous, and the accuracy is not high

Abstract

The invention discloses a method and equipment for detecting user pronunciation, which are used for analyzing and evaluating the accuracy of the user pronunciation more precisely. The user pronunciation detecting method provided by the invention comprises the following steps: acquiring input audio signals, and determining user voice signals in the audio signals; determining the pre-stored standard voice signals corresponding to the user voice signals, wherein the voice contents of the user voice signals and the standard voice signals are the same; and comparing the length of the user voice signals with the length of the standard voice signals to determine the user speed.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method and device for detecting user pronunciation. Background technique [0002] The predecessor of the language learning machine is the repeater, which is a tool for practicing listening and speaking. With the development of technology, the function of correcting pronunciation has been added to the language learning machine. Through the intelligent scoring system, it can automatically evaluate the quality of the user's pronunciation. This kind of repeating machine can also be called a sound correcting machine. [0003] The intelligent scoring system in the existing language learning machine generally only adopts simple VAD technology, and the scoring is often very inaccurate, similar to the scoring system in the karaoke machine. The high-end intelligent scoring system generally uses speech recognition technology, but the implementation complexity is relatively high,...
