I remember when I first read about Seungyeon studying in the states before her debut.At the time I tried to find any video of her talking in english, but without any luck. I'm really happy to see a few posted here! Can't really hear more than 1 line from her, but I'm still satisfied haha.
I guess she understands english pretty well (she used the right words quite easily). But obviously, since she's probably never speaking english, it's hard not the lose the pronunciation.
