The group of muscles that moves the hyoid bone and larynx helps with the processes of speech and swallowing.

The group of muscles that moves the hyoid bone and larynx, known as the suprahyoid and infrahyoid muscles, play an important role in speech and swallowing. The movement of the larynx is particularly important for controlling the flow of air during speech production, while the hyoid bone plays a role in supporting the tongue and other structures involved in swallowing.
