On The Timbre Features Of Interactive Variables Of Teachers' Language

The paper selects a certain amount of teachers' in-class sentences which embody different interactive types.The study mainly aims to explore timbre performance of different interactive types and meta-functions under the contrast of three different circumstances,namely,TCFL classroom,daily communication and reading.The significance of this experimental study is to enrich the study of teachers' language and the quantitative study of style,and,on the other hand,provide a reference to the naturalness of "teacher robot" in speech synthesis.This paper mainly adopts an experimental and phonological research method.The total amount of subjects is 20,men and women each 10.By means of simulation context,recording,listening and screening,the paper selects teachers' in-class sentences which meet the requirements under the contrast of three different circumstances.The paper analyzes the first,second and third formants and uses Spss to analyze the variance.The experimental results show that there is a significant difference in the timbre performance of the highly interactive "instruction" under the three discourse modes compared to the less highly interactive "compliment".Secondly,the interpersonal function and the conceptual function under the three discourse modes show significant difference,and the discourse function is not the same case.The experimental results also show that the interpersonal proximity of the teachers' language falls in the middle between daily conversation and reading.It specifically shows in timbre performance that the fist formant increases,the second formant descends and the third formant descends when the interpersonal distance draws nearer.
