1. Lungs:
* Function: Provide the airflow necessary to create sound. The lungs push air out of the body, which then passes through the other organs of speech.
2. Diaphragm:
* Function: A large muscle that sits below the lungs. It contracts and relaxes to control the flow of air from the lungs, helping with breathing and speech.
3. Trachea (Windpipe):
* Function: A tube that carries air from the lungs to the larynx (voice box).
4. Larynx (Voice Box):
* Function: Contains the vocal cords, which vibrate to produce sound. The larynx also protects the airway during swallowing.
5. Vocal Cords:
* Function: Two folds of mucous membrane that vibrate when air passes over them, producing sound. The tension and length of the vocal cords can be adjusted to change the pitch of the voice.
6. Pharynx (Throat):
* Function: Connects the larynx to the mouth and nasal cavity. It acts as a resonating chamber, modifying the sound produced by the vocal cords.
7. Mouth:
* Function: Contains the tongue, teeth, and palate (roof of the mouth), which are all involved in shaping and articulating sound.
8. Tongue:
* Function: A muscular organ that moves around the mouth to shape sounds. It helps with articulation and provides clarity to speech.
9. Teeth:
* Function: Help with articulation and sound production. They can be used to create sounds like "f," "v," and "th."
10. Palate (Roof of the Mouth):
* Function: Separates the mouth from the nasal cavity and helps with articulation. The soft palate can be raised to block air from escaping through the nose during speech.
11. Nasal Cavity:
* Function: Contributes to the resonance and quality of some sounds, particularly those that involve air passing through the nose.
12. Lips:
* Function: Help with articulation and sound production. They can be used to form sounds like "p," "b," and "m."
These organs work together in a complex and coordinated manner to produce speech. Any issues with the function of these organs can lead to problems with speaking clearly.
