Is there a word that can be used to describe the act of speaking over another person? Looking particularly to describe the act in the context of a debate where a speaker is unable to respond due to repeated interjections.
- shouting to interrupt a speech with which you disagree
Surely Mitch (see answers) is right:
speaking over others
is quite appropriate:

This attention can be demanded by speaking loudly, speaking over others, using attention-seeking body movements, and ignoring feedback and the views of others.
It actually doesn't mean to speak over someone, but this word in terms of the elements that make it up would be perfect if it didn't already have a different meaning:
To talk too much or too long about (something).
To speak too much; to use too many words.
Maybe one of these could be used and evolved over time to mean to talk/speak over someone, like a lot of words change meaning over time. Just requires enough people to start using it that way. 😉
