An experimental study on the intergenerational differences of vowel patterns in Pulandian dialect
Based on the Vowel Pattern theory,this paper investigates the cross-generation differences of vowel patterns of Pulandian local people by adopting the method of acoustic experiment.It is found that differences do exist among different generations in vowel patterns;the younger the generation is,the clos-er of their vowel patterns to that of Putonghua,which indicates that the vowel patterns of Pulandian dia-lect have been constantly changing towards Putonghua.The powerful influence of Putonghua as well as people's language attitudes are the reasons for the change.
