You could practice. Announce that you want to say something even though you fear it is unpopular or will be poorly received. Then express an opinion you know everyone already shares even though no one has said that explicitly. Warning: this will lower your status.

It may lower your status depending on your initial status and in what manner you speak. It can also be a step up from being someone whose mannerisms convey that they would be too intimidated to do so. Another potential outcome is that of being respected more but liked less.
