mouthful of marbles

Indistinct, slurred articulation

A mouthful of marbles describes speech that is slurred, garbled, or difficult to understand—as if the speaker's mouth were literally full of marbles: He mumbles like he's got a mouthful of marbles.

The phrase typically criticizes unclear enunciation rather than accents or speech impediments.
