Why did the actor pronounce 程, "du" instead of "cheng"? To improve my Chinese listening, I decided to watch 天下一碗 (Tian Xia Yi Wan), as actors tend to speak with very precise and clear tones.

In the link, Liu laoye says:


  "如果是一时意气用事的话, 岂不是耽误了子女的前程了吗".


I do not know why 程 is pronounced "du" here? is it a typo?

(But 前度 does not make sense to me either).
It's 前途 (qian tu) which has pretty much the same meaning as 前程. Probably a typo in the subtitle or the actor said it differently from the script, the director thought it was fine, but the subtitle comes from the script.
