Thefir's Zone of Communication

You create a magical zone that breaks language barriers altogether within a 60 foot sphere centered on a point within range. For the duration of the spell, all creatures within the field can understand each other's language when communicating, provided they have at least one language and has Intelligence score of 3 or higher.

At higher levels
When casted at 7th level or higher, affected creatures also understand any scripts known to at least one of the creatures. If casted at 8th level or higher, affected creatures can communicate telepathically.
