Speech is the verbal means of communicating. Speech consists of the following:
- Articulation: How speech sounds are made (e.g. children must learn how the make the /r/ sound in order to say 'rabbit' instead of 'wabbit').
- Fluency: The rhythym of speech (e.g. hesitations or stuttering can affect fluency).
- Voice: Use of the vocal folds and breathing to produce sound (e.g. the voice can be abused from overuse or misuse and can lead to hoarseness or loss of voice).
When a person is unable to produce speech sounds correctly or fluenty, or has problems with his or her voice, then he or she has a speech disorder.
