outspeak

Outspeak means to speak more boldly, loudly, or effectively than someone else, or to express something that others hesitate to say.

She outspeaks everyone at the meetings, never afraid to challenge the boss.

The word can also mean to speak out or declare openly, though this sense is somewhat archaic.

In contemporary use, it often implies surpassing others in vocal assertiveness or willingness to voice unpopular opinions.
