Visible Speech is a system of phonetic symbols developed by British linguist Alexander Melville Bell in 1867 to represent the position of the speech organs in articulating sounds. Bell was known internationally as a teacher of speech and proper elocution and an author of books on the subject. The system is composed of symbols that show the position and movement of the throat, tongue, and lips as they produce the sounds of language, and it is a type of phonetic notation. The system was used to aid the deaf in learning to speak.

Alexander Melville Bell was a teacher and researcher of physiological phonetics and was the author of numerous works on orthoepy and elocution.
