Babble

You inflict a curse of uncontrollable bouts of gibberish. Choose a humanoid or fey that you can see within range. The target must succeed on a Wisdom saving throw or babble incoherently for the duration. While babbling, the target can't speak, make bite attacks, use breath weapons, or use spells that require a vocal component. At the end of each of its turns, the target can make another Wisdom saving throw. On a success, the spell ends for the target.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional humanoid or fey for each slot level above 3rd. The humanoids or fey must be within 30 feet of each other when you target them.
