Definition

VowelA speech sound produced with relatively littleobstruction of airstream in the vocal tract

Consonant

A speech sound produced with a complete or

partial obstruction of the air stream in vocal

tract

deal with the physiologicalmechanism of speech production.

how speech sounds are produced.

VOWEL ARTICULATION

Height of articulation:(Tongue height)

- High: top of the mouth

- Mid: middle of the mouth- Low: bottom of the mouth

beat /bi:t/ - bat /b&t/


6/22

Frontness of articulation: (tongue part)

- Front: the tip of the tongue

- Central: the middle of the tongue- Back: the part of the tongue closestto the throat

E.g: fit /fIt/ - foot /fUt/


7/22

Tenseness of articulation

- Tense: with a tensed tongue

- Lax: with a relaxed tongueE.g: wheat /wi:t/ - wet /wet/


8/22

Roundness of article: (shape of lips)

Rounded: with the lips pushed forwardin an O shape

Unrounded: with the lips pulled in andback

E.g: food /fu:d/ and foot /fUt/

ARTICULATION


11/22

Describing the consonant sounds:

The manner of articulationThe place of articulation

The force of articulation


12/22

The manner of articulation

Interaction between the various articulators andthe air stream

The manners of articulation are:

PLOSIVE AFFRICATIVE FRICATIVE

NASAL LATERAL APPROXIMANT


13/22

MANNER OF ARTICULATION

PLOSIVE /p/ and /b/

AFFRICATIVE /t/- //

FRICATIVE /f/- /v/

NASAL /m/- /n/

LATERAL /l/

APPROXIMANT /r/- /w/


14/22

PLACE OF ARTICULATION

Bilabial Using closing movement of both lips, e.g. /p/ -/b/

Labio-dental Using the lower lip and the upper teeth, e.g. /f/-/v/

Dental The tongue tip is used either between the teeth orclose to the upper teeth, e.g. ///

Alveolar The blade of the tongue is used close to thealveolar ridge, e.g. /t/- /s/.

Palato-alveolar The blade ( or tip) of the tongue is used justbehind the alveolar ridge, e.g. //-//

Palatal The front of the tongue is raised close to thepalate, e.g. /j/

Velar The back of the tongue is used against the softpalate, e.g. /k/- //

GlottalThe gap between the vocal cords is used to make

audible friction, e.g. /h/


15/22

FORCE OF ARTICULATION

Fortis or strong: it is related to unvoicedsounds

Lenis or weak: it is related to be voicedsounds.

A branch of physics, andinvolves the study of the speech

signal ( the sound wavesproduced when a speaker

speaks)

Acoustic features play a muchmore important role inaccurately describing vowels as

vowels are sonorous sound.
