The crowd met lines of his speech with chants of his catchphrase, "Yes, we can."

Does met means responded?
Hi LiJ
Yes, "responded to his speech."
Students: Are you brave enough to let our tutors analyse your pronunciation?
Hi, I think that you can't use met lines here.
If so, is "meet lines" an idiom?
Thanks, CB and NJ.
Students: We have free audio pronunciation exercises.
I found this line on CNN.com, and wondered what it means as I couldn't find it in my EJ dictionary. From the context, I thought it could mean 'respond' and wanted to hear members' opinions.
