In English there are only 5 vowel letters to describe the 21 vowel sounds on this chart, so the symbols between slashes are from the International Phonetic Alphabet (IPA). The chart attempts to illustrate the hand shapes and movements for each vowel sound.

Originally devised to help severely speech and language handicapped children to see a sound and hear a letter by the use of easy and logical hand cues, the Cued Articulation system has, over the last three decades, proved an invaluable teaching tool.

This instructional, interactive DVD which includes demonstrations of the cues and sounds is available to compliment the book.|Originally devised to help severely speech and language handicapped children to see a sound and hear a letter by the use of easy and logical hand cues, the Cued Articulation system has, over the last three decades, proved an invaluable teaching tool.
