- For 'speech', meaning a talk, see Public speaking
Speech is made up of sounds that are made when air passes through the voice box and is shaped by the lips, tongue, teeth, nose and palate.
To make speech a person has to be able to:
- choose speech sounds
- put them into a sequence
- produce sound in the voice box
- use the lips, tongue, teeth, nose and palate to make the sounds
Difficulties can happen at any stage of this 4 stage sequence. Difficulties at stages 1 and 2 are known as phonological difficulties while problems at stages 3 and 4 are known as articulation diffiulcties or motor co-ordination difficulties. A speech and language therapist can help work out the stage of the sequence that has difficulties and give therapy.
A speaker may say something, and if it is heard, what the speaker says may be understood. Sometimes language is difficult to understand. It may be vague, confusing, or even misleading. It may be easy or difficult.
The same speech may be put in different languages, by means of translation.
