As part of the Vocal component of this spell, you say a catchy phrase that has a response to it or lyrics of a well known song. Each creature within range that can hear you and is hiding from you, makes a Wisdom saving throw or reveal its position by responding to the catchy phrase or singing along with the lyrics to the song. If a creature is invisible it does not break it, but you do know it's general position.

A creature needs to be able to speak and understand the language you use to cast this spell.
