SPEECH ORGANS

SPEECH ORGANSTHE WAY THE SOUNDS ARE PRODUCED

SPEECH ORGANS

JAWTEETHBUCCAL CAVITYPart of the vocal tract lying between the Pharynx and the lips, containing the tongue and the teeth and bounded on top by alveolar ridge, the palate and the velum.

Air flow is directed outwards the oral cavityThe enamelled bony structures set in two curving lines in the upper and lower gums. The upper teeth (rarely the lower ones) may serve as passive articulators.Also called mandible. Its a horseshoe-shaped that holds the lower teeth and forms the lower jawline and chin.

SPEECH ORGANS

TONGUELIPSNOSTRILEither one of the external openings to the nasal cavity in the nose. Either of the two fleshy, manoeuvrable organs at the entrance of the mouth. The lips are important in speech. They can be pressed together to produce the sounds p and b, brought into contact with the teeth (as in f and v, or rounded to produce the lip-shape for vowels like u. The tongue is a very important articulator and it can be moved into many places and different shapes. The tongue is divided into different parts: tip, blade, front, back and root.

SPEECH ORGANS

SOFT PALATEHARD PALATENASAL CAVITYThe large cavity lying above the oral cavity and connecting the nostrils to the pharynx. When the velum is raised, the nasal cavity is closed off from the rest of the vocal tract.The hard bony structure at the top of the roof of the mouth, just behind the alveolar ridge.The flexible sheet of muscular tissue wich makes up the rear part of the root of the mouth, just behind the palate. Its connected to the palate by a hinge which allows it to be raised and lowered.

SPEECH ORGANS

ESOPHAGUSLARYNXPHARYNGEAL CAVITYTo produce consonant sounds articulated in the back of the mouth or throat.A complex, mostly cartilaginous, structure connecting the trachea to the pharynx and acting as a valve through which air must pass during breathing and speech.The tube connecting the stomach to the pharynx.

SPEECH ORGANSDIAPHRAGMLUNGSTRACHEAThe cartilaginous channel connecting the lungs to the larynx through which air passes during breathing and speaking.A pair of spongy, saclike organs located between the chest and playing a vital role in respiration and in providing a pulmonic airstream for speech.

The dome-shaped muscular partition between the chest and the abdomen, partly responsable for contracting the lungs during breathing.
