I noticed recently that the Hanyu pinyin "i" in chī 吃 and chǐ 尺, aren't the same as the "i" in zi 子 or si 四. I speak English with a standard American accent (grew up in New England), and I could not think of any words I say in English that use this vowel sound.
Is it not a sound in English? Is this sound used in English? What is an example? Am I missing something obvious?
I tried poking around online, but I am hopeless with the IPA system, so it's hard for me to understand what I find or if it is relevant. I did find this previous post on this forum describing the difference between the two vowel sounds, but it doesn't answer my question.
For context: I learned Mandarin in Taiwan and from Taiwanese people, so I am pronouncing Chinese words with (my best approximation of) Taiwanese Mandarin pronunciations.
