Morphology
lip + reader
The meaning 'a person or device that reads/analyzes lips' is directly compositional from 'lip' (mouth edge) + 'reader' (one who reads), so a learner who knows both words can infer it denotes an agent that reads lips. This noun‑combination follows a common English pattern (noun + reader/agent) and has clear parallels in other languages, making it immediately comprehensible to a B1 learner.
Etymology
Lip reader for a computer comes from the same image: the program 'reads' the movement of the lip on video like a person. That's why the expression means 'a computer program that understands speech by watching lips'.
