Phoneme awareness is necessary for learning and using the alphabetic code

English uses an alphabetic writing system in which the letters, singly and in combination, represent single speech sounds. People who can take apart words into sounds, recognize their identity, and put them together again have the foundation skill for using the alphabetic principle (Liberman, Shankweiler, & Liberman, 1989; Troia, 2004). Without phoneme awareness, students may be mystified by the print system and how it represents the spoken word.

Students who lack phoneme awareness may not even know what is meant by the term sound. They can usually hear well and may even name the alphabet letters, but they have little or no idea what letters represent. If asked to give the first sound in the word dog, they are likely to say “Woof-woof!” Students must be able to identify /d/ in the words dog, dish, and mad and separate the phoneme from others before they can understand what the letter d represents in those words.
