"Lip-synching" Natural Recordings by Native Speakers
Lip-synching is the act of pretending to sing or speak by moving one's lips and mouth to match the sounds, while someone else provides the actual vocal performance. It is often used in music videos, films, and television shows where the actor or performer cannot sing or speak the dialogue themselves.
Liopelmidae is a family of extinct frogs that lived during the Jurassic and Cretaceous periods. They were characterized by their unique cranial morphology, with a distinctive group of bones at the base of the skull. The Liopelmidae family is important in the study of amphibian evolution, as they provide a link between the earliest frogs and the more modern species.
To lip-read is to decipher what someone is saying by observing their lip movements and facial expressions, without actually hearing the words spoken.
