Brilliant! You REALLY need to get that info over to someone who
can fix the way that Chinese is considered in English countries
because our bias is showing and I never saw it 'til you pointed
it out just there. After all, what makes their "intonations" any
stranger than our "vowels"? Nothing. They're the same. " Way
back when I was studying Chinese, we were taught that
intonations were relevant to the dialect, and might change the
meaning of an utterance with similar pronunciation from that
language. Back to English.
We are, or at least I was, taught that the vowel is 'a, e, i, o,
u,' and sometimes 'y'. Question: What makes a vowel a vowel, if
not intonations? Reverse culture shock!"* - not me
