Characters being able to understand what others are saying by reading their lips. Usually an ability of deaf people, though anybody with good eyesight at least can have it. However, this ability is greatly overstated in fiction where the deaf are concerned, since it's fairly difficult to master and not all deaf people can do it, and even those that can are never perfect. In English, less than half of spoken sounds can be seen on the lips; the rest rely on the throat and tongue movements. That's how we get the joke about how "olive juice" looks exactly like "I love you." This trope is arguably similar to how so many blind people in fiction have Super Senses, in that it introduces a character with a disability while minimizing the issues such a person would realistically face.

- In practice, lipreading is fairly difficult skill, with around 25-50% success on identifying words; the rest is using logic to fill in the blanks. Not all deaf people can lipread, as some would assume, and to top it off, it also varies depending on the individual deaf person's hearing level. And to add to mess, it also depends on the person speaking, especially if the person mumbles, has a strong accent, or has facial hair that covers the lips. Generally, deaf people have a much easier time understanding someone they know personally—family and friends—than complete strangers.

Samantha Bee demonstrates.
