The sound can include intelligible speech. You can identify a sound the subjects know and they imagine it doing what you describe as you cast
the spell. You could have orc warriors imagine
the sound of their chieftain calling for help, even if you've never heard their chieftain and even if the chieftain speaks in a language you don't understand.
