Notes on American phonetic transcription

Description

The content of the article is basically from Lai's "American Phonetic standard".

Easy to confuse pronunciation [I] with [?]

The latter pronounced the mouth more relaxed than the former, with flat lips.

• Eat [it] it [? t]
• Heat [hit] hits [H?t]
• Sheep [? IP] ship [?? P

[?] And [?]

The former mouth should be more open.

• bed [b?d] bid [B?d]
• Letter [' L?t?] litter [' l?t?]
• Lever [' l?v?] liver [' l?v?]

[U] and "WU"

The actual difference between the two sounds is very large, [u] lips are not prominent.

[U] and [?]

[?] Some places will be written in uppercase U. -Food [FUD] good [ɡ?d]-fool [ful] full [f?l]-pool [pul] pull [p?l]

[?] And [?]

These two sounds can be said to be the same, but the strength of the problem, and the position of the scale is different. The former is more than two syllables in the non-stressed section of the word, the latter appears in a single syllable or a heavy syllable word.

[?] It's been a bad read for years.

• Cup [k?p] cop [KⱭP]
• Color [? k?l?] collar [? kɑl?]
• Hut [h?t] hot [hɑt]

Other precautions

• [E], [o] is a double vowel
• [t?] [T] pronounced ambiguous, between [l] and [t]
