I Understand

Pimsleur have a great Cantonese course, although there are only 30 lessons (unlike their Mandarin which runs to 90 or so). A while ago I started drawing up for myself transcripts of the dialogues which precede each lesson.
Here's the first:

請問小姐,你識唔識聽英文呀?

ceng2 man6 siu2 ze2, nei5 sik1 m4 sik1 teng1 jing1 man2 aa3?

Excuse me miss, do you understand English? 

唔識聽.我唔識聽英文.

m4 sik1 teng1. ngo5 m4 sik1 teng1 jing1 man2.

No, I don't understand English.

我識聽一啲廣東話.

ngo5 sik1 teng1 yat1 di1 gwong2 dung1 waa2.
