What a pity that there is no audio for this, especially as it is about differentiating among similar spelling...
I believe that's the team's intention to help you distinguish between lookalike vowels <a> and <ă>
Seriously. The fact that the name 'An' sounds so similar to 'Anh' screwed me up several times.
When I first read it, I assumed it was the English word, "a/an" and that there was some typo.
I had no idea that "An" was a name so I thought the sentence would be grammatically incoherent as "an eats". Please make this less confusing.
Can someone help explain the difference between the sounds? An sounds the same as ăn to my untrained ear.
I know this is super old (3 years ago), but I'll answer it.
A is a sound like in the word "fat" (that's not perfect, but as close as I can think of to describe it over text), and Ă is an "uh" sound, as in "cut."
Additionally, A is a long vowel sound, so most of the word goes into the A sound. Like Aaaan. The "n" part is very truncated. Ă is a short vowel sound, most of the word goes into the n sound. Uh-nnnnnn. The Ă sound is very truncated.
I'm not 100% sure but I think ăn sounds like ah-n? Something like that unless I'm mistaken
Why doesn't that sentence make sense to you? Who eats? - Ai ăn? -> An eats - An ăn.
In Vietnamese, 'An' is a person's name and 'ăn' means 'to eat' so the sentence does make sense :D
I've tried on Firefox, Chromium and Opera but there isn't audio for this example sentence anywhere.
