Removing 100s of "uhm" and "ahh" from an audio?

[tuqqer]

Any of you know of a software that will allow one to remove a lot of "uhm/ummm" sounds from someones audio file? I only have used Audacity before, but I don't think it has that ability.

Normally, I'd just manually delete each one but this speaker has well over 100 in a 30-minute talk.
