I caught a quiet muttering at the back of the room.

She mutters a quick apology before turning away.

At the staff meeting, the mutters grew into a chorus of complaints.

Her mutterances were barely audible over the hum of the refrigerator.

Her mutterance barely reached him over the roar of the crowd.

At the food festival, I tried mutter paneer for the first time and loved its creamy, spiced sauce.
