Speech refers to the production of sounds within words. When there are speech sound difficulties it affects an individual’s clarity and ability to be understood.
Speech consists of the following:
How speech sounds are made (e.g., children must learn how to produce the "r" sound in order to say "rabbit" instead of "wabbit").
All children make pronunciation mistakes when they are learning to talk like adults. These patterns are called phonological processes, or phonological deviations. (e.g. children up until the age of 2 may omit the final consonants from words /dog/ à /do/) There are many phonological processes found in children's speech while they are learning the adult sound-system of English.
Use of the vocal folds and breathing to produce sound. If your child’s voice sounds husky or you are over concerned that his / her voice is high, soft or nasal, or if it is painful or uncomfortable for her/him to talk he/she may have a voice problem.
The rhythm of speech (e.g., dysfluency or stuttering can affect fluency).
