Problems solved by technology

[0007] All methods based on phonetic symbols are unable to describe the linking phenomenon of language
When performing phonetic notation, the phonetic notation of connected and disjointed is the same, so it cannot evaluate whether some phrases (such as "a lot of") are connected accurately
[0008] All methods based on phonetic symbols cannot accurately judge the exact attribution of nasal sounds in words

Abstract

The invention relates to the field of computer aided language teaching, and provides a method for estimating pronunciation. The method comprises the following steps of: receiving an actual measurement sound signal of single language or a plurality of languages; generating an actual measurement audio frame signal according to the actual measurement sound signal; and comparing the actual measurement audio frame signal with a standard audio frame signal to estimate the quality of the actual measurement sound signal. The invention further discloses a system for estimating pronunciation. With the method and the system for estimating pronunciation provided by the invention, the quality of pronunciation can be estimated more accurately and effectively in a simple way.

Description

technical field [0001] The present invention relates to the field of computer-aided language teaching, and more particularly to methods and systems for pronunciation assessment. Background technique [0002] Language is a tool for human communication. Today, with the increasing degree of internationalization, mastering multiple languages ​​has been respected by more and more people. Under such background conditions, various ways of using computer-aided oral language learning have emerged as the times require. [0003] Patent 98103685.6 discloses a method for evaluating learners' pronunciation by using phonetic symbols. This method designates some common mispronunciation patterns according to expert knowledge, and gets the score by comparing the speaker's pronunciation with the standard pattern, so as to obtain the information of whether the speaker's pronunciation is accurate, so as to evaluate the speaker's pronunciation quality. The defect of this method is that the erro...
