What muscles are used to talk?

To speak, you use your stomach muscles, lungs, voice box, tongue, teeth, lips, and even your nose. Your brain coordinates it all. Speech actually starts in the stomach with the diaphragm. This is a large muscle that helps push air from the lungs into the voice box.

How do humans talk?

Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx (voice box), and the articulators. The lungs, the "pump" must produce adequate airflow and air pressure to vibrate vocal folds.

Why is it physically hard to talk?

Difficulty with speech can be the result of problems with the brain or nerves that control the facial muscles, larynx, and vocal cords necessary for speech. Likewise, muscular diseases and conditions that affect the jaws, teeth, and mouth can impair speech.
