You cause the targets to believe they hear any sound you imagine, as well as the image of any object, creature, or force you imagine or identify for the targets to imagine. The sound can include intelligible speech. The phantasm includes visual, auditory, olfactory, tactile, and thermal components, the phantasm follows a complex script without your concentration, and it can react to stimuli the targets perceive.

Instead of precisely imagining a sound, you can identify a sound the subjects know and they imagine it doing what you describe as you cast the spell. For example, you could cast this spell on orc warriors and have them 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. All targets hear the same hallucination.
