- W2371009477 abstract "Fundamental frequency(or pitch),usually named as F0,is the vibration frequency of vocal cord during the production of voiced sounds.In a syllable or continuous voice paragraph,F0 changes with time and yields the fundamental frequency(or pitch) curves.It is particularly important to descript and investigate the F0 curve because it usually reflects the rhythm information,such as tone and stress.This paper first proposes a new method to describe F0 curve——the derivative domain codes,and then it discusses the role of the coding method on the rhythm in the evaluation of speech pronunciation.Experimental results show that the method can be used to evaluate the English prosody.The correlation coefficient between the subjective and objective scores of pitch extreme difference improves from 0.38 to 0.49." @default.
