As a college English major, do you have high requirements for the accuracy of phonetic symbols?

Well, there will be a professional pronunciation course to learn phonetic symbols, and it also requires a test, but it is not taken seriously. Because there is no pronunciation test in Vocational 4 and Vocational 8. And many people can't correct it, because years of pronunciation habits cannot be changed all at once. Moreover, everyone has his or her own speech blindness, and there are always a few sounds that are problematic. Therefore, English majors will have more accurate phonetic symbols than non-English majors, but everyone's situation is different.
