Organs of speech

The nature of speechSpoken language consists of successions of

sounds emitted by organs of speech together with certain attributes.

These successions of sounds are composed of:

Speech-sounds

Glides

Types of pronunciationNo two persons of the same nationality

pronounce their own language exactly alike.

Reasons:

LocalitySocial surroundingsEarly influences

Breath and voice

Vowels and consonants

Plosive

When active articulator comes in firm contact with a passive one, forming a structure of complete closure, the air streams built up behind this closure. The articulators separate suddenly producing an explosive sound called plosion.

a.a.

affricative

When active articulator comes in firm contact with a passive one, forming a structure of complete closure, but instead of opening suddenly producing an explosive sound, they come apart slowly into the fricative position.

a.a.

fricative

When active articulator comes into light contact with a passive one, forming a structure of closure approximation the air has to force its way out, making a noise called friction.

a.a.

lateral

When active articulator comes in firm contact with a passive one, and the air escapes down one or both sides of the contact.

a.a.

nasalThe velum must must be lowered, and there must be a structure of compete closure somewhere in the mouth, so that the air escapes through the nose.

Semi-vowelThese sounds are produced with an approximation of the articulators which is too open to cause friction
