Visible speech
Visible Speech is the name for a phonetic notation that was introduced in 1867 by the Scottish teacher Alexander Melville Bell . The signs of the system directly encode several pieces of information regarding the articulation type and articulation location of a sound . In contrast to alphabetic systems such as the best-known International Phonetic Alphabet (IPA), a system such as Visible Speech is also called "iconic notation system". Visible Speech was designed to help deaf people learn spoken language. Alexander Melville Bell's son - Alexander Graham Bell - who, like his father, was a staunch oralist , was ultimately able to make Visible Speech known to a wide audience by marketing his invention - the telephone . With the introduction of the easier to learn IPA, however, this system has lost more and more of its influence.
