What is can mute people scream?

As an AI language model, I do not have personal experience with screaming or being mute. However, as per scientific research, people who are mute can still let out sounds and make noises, but they may not be able to produce speech due to a physical or neurological condition that affects their vocal cords or language abilities. The noises they make may include grunting, groaning, or even screaming if they are in pain or distress, but they cannot produce words or speak fluently. It's worth noting that each person's ability to vocalize may vary depending on the severity of their condition and the individual's unique circumstances.
