An Experimental Study On Monosyllabic Tone By Laotian Chinese Learners

This research takes primary and intermediate Laotian Chinese learners as the research object,analyzes the acquisition of Chinese monosyllabic tones through production and perception experiments,finds out the characteristics and causes of the errors,and puts forward relevant teaching suggestions on this basis.This research includes two experiments,production experiment and perception experiment.In the production experiment,the monosyllabic pronunciation of Laotian Chinese learners at primary and intermediate levels was compared with the pronunciation of Chinese speakers.The results showed that there was a gender difference between male and female speakers at primary Chinese level,there was no significant difference in the intonation value and shape adjustment of female learners at primary level.However,male learners at primary level have insufficient increase in Tone2,and the error in Tone4 is not enough decrease.By the stage of intermediate level,the errors of Laotian Chinese learners have been corrected.In the pronunciation experiment,it can be seen that Laotian Chinese learners’ monosyllabic output becomes better and better with the improvement of their Chinese level.In the perception experiment,the error rate and the specific types of errors in each tone and whether there is bidirectional confusion.The experimental results show that Laotian Chinese learners perceive Tone4 better than the other three tones,and also found that there is a bidirectional confusion between Tone1 — Tone2 and Tone2 — Tone3 in elementary level,but this phenomenon no longer appears in intermediate level Chinese learners.In other words,the perception and recognition ability of Laotian Chinese learners improves with the improvement of Chinese level.This research further analyzes the errors of Laotian Chinese learners and the causes of errors.We believe that the main causes of errors include the influence of mother tongue background,the influence of native teachers on tone teaching,the influence of individual learner factors and the influence of tone content design in textbooks.On the basis of this,this paper puts forward some suggestions on how to increase the perceptual training of confusable tones,the contrast teaching of tones and tones between Chinese and Laotian and the visual teaching of pronunciation.The research in this paper is conducive to improving the phonetic appearance of "Talk Da Talk" of Laotian Chinese learners.In addition,this study has certain value for enriching the study of nationalized Chinese pronunciation,and also has certain significance for the construction of nationalized intelligent phonetic learning platform.
