Abstract
The article conducts acoustic experiments on the pronunciation of the “er” which means “two” in Chinese by learners from different language background by referring Praat speech analysis software and scripts, and analyses acoustic parameters of the slope, F1, F2, F3, difference by combined with the five-level scoring method and one-way ANOVA method.The study shows that as for the “er” pronunciation of learners who speak in S&P, their F2 of retroflex vowels rises, and F3 falls, and the difference value between F3 endpoint and F2 endpoint is small, which means that F3 and F2 are closer to each other. The key characteristics to the learner's “er” pronunciation acquisition depend on the slope of F3 and the difference value of F3. The greater the slope of F3 falls, the smaller the difference value, which indicates the “er” pronunciation of learners from different language background will draw near to S&P “er”.
