Abstract

The invention discloses an objective examination method of breach sound and affricate in standard Chinese, including the steps: receiving input voice; syncopating the input voice; distilling distinguishing characteristics; giving a mark according to an evaluating model; and obtaining a pronunciation score. By applying the objective examination method and adopting the distinguishing characteristics which can better reflect the pronunciation essential to distinguish the breach sound and the affricate, the better distinguishing performance can be obtained.

Description

technical field [0001] The invention relates to the technical field of objective testing of Mandarin Chinese, in particular, the invention relates to an objective testing method for voiceless fricatives and affricates in Mandarin Chinese. Background technique [0002] In the learning of Mandarin Chinese, since the pronunciation duration of the initial consonant is relatively short, the pronunciation process includes three stages of blocking, holding and removing obstruction, and the requirements for the pronunciation part and pronunciation method are relatively high, so the pronunciation of the initial consonant is more difficult , especially some initial consonants whose pronunciation methods and pronunciation parts are relatively close, learners are easily confused during the learning process of Mandarin due to the influence of their own mother tongue and local language. [0003] Generally speaking, in the process of learning a second language, learners are always accustom...
