[t̪ʰa ɕɥe ɕi tʂuŋwən]
This pronunciation is according to the book The Sound of Chinese published by Cambridge University Press. I added the ̪ because the book dictates to pronounce the /t/ with ̪. The same book does not specify whether to compress round or protrude round for the rounded vowels but I use protruded rounding for the back vowels and compressed rounding for the front vowels. Despite me knowing the International Phonetic Alphabet and phonetics and phonology well, why does my pronunciation sound foreign and not like Standard Chinese or 普通话 accent?
For example, the consensus to pronounce [m] is to both lips together and and voice and breath out of the nose, so the [m] should be made regardless of language. The same thing should apply to my sample pronunciation but it still sounds like not Standard Chinese or 普通话 accent. I understand that vowels are spectrum the [i] in one language may be more backward or lower than in the other language, so that is why I only use cardinal vowels.
[ə]
Also, I was taught that this sound was made by merely relaxing the mouth and lips. It also exists in my English accent Received Pronunciation.
