I need this for work

there is an MP3...
http://www.divshare.com/download/14867494-ed6
it is brief, it is about 17 seconds.
It's in English, but the last sentence is in Chinese... well, I think it is Chinese!
If so, can you please translate this little sentence to me?
But not only the translation (I read it is something like "You promised never to bring that up!"..), I need even (and ABOVE ALL >__<) the transliteration of the chinese sentence in roman letters^^
Like "nihao"! ;P
hehehe
thank you very much!
