How do you talk with the microphone on playstation home?

May be...

Hold R2, and speak into the microphone. No, there is no way you can tell. But, for the people who do have microphones, when they talk, a little sound icon pops up right next to their name. That's one way you can tell.



Hope I helped!

Hold down the R2 button then talk in your microphone like any other game.

r2 buddy you have to hold it down when you talk sucks right
