2/32

Articulation

Formation of discrete(individual)

speech sounds


3/32


4/32

Points of articulation

x Points of the vocal tract involved in

articulation -but which do not move

x Teeth

x Alveolar ridge

x Hard palate

x Soft palate (velum)

x Uvula


5/32

Articulation

Consists of bringing an articulator

into contact with a point ofarticulation


6/32

Tongue- most mobile of all

articulatorsx Can move from front to back

x Can move up and down

x Can move from side to side


7/32

Tongue can be divided into five

regionsx Tongue tip (called apex)

x Tongue front

x Tongue center

x Tongue back ( called dorsum)

x

Tongue root


8/32

Lingual Sounds

Sounds that are articulated with the

tongue


9/32

We oftern designate the part of

tongue involved in articulationx Fronto-adjective indicating front part of the

tongue

x Dorso-adjective indicating back(dorsum)of

the tongue


10/32

Labials

Sounds which are articulated with the

lower lip


11/32

Bi-labial

Bringing the upper and lower lips

together


12/32

Teeth

x Since they are immobile, the upper and the

lower teeth are classified as points of

articulationx Sounds articulated at either the upper or

lower teeth are called Dental

x The term Dental refers to a point ofarticulatiom


13/32

Description of Articulation

x When we describe the articulation of a

speech sound,we indicate both the

articulator and the point of articulationx If the articulator is the lower lip and the

point of articulation is the upper teeth, we

combine the terms labial(for lip) anddental(for teeth) labio-dental


14/32

Labio-dental

Articulator/Point of articulation


15/32

Pronounce the word For

x The initial sound of this word is articulated

with the lower lip touching the upper teeth

x Labio Dental

x Lower lip teeth

x articulator point of articulation


16/32

Pronounce the word through

x The tip of the tongue touches the upper

teeth

x Linguo- Dental

x Tongue teeth

x Articulator point of articulation

x Also called Interdental

x upper lip

x lower teethx upper teeth

x tongue


19/32

Alveolar Ridge

x Just behind the upper front teeth,there is a gum

ridge called the alveolar ridge

x Sounds articulated at this ridge are calledalveolar sounds or alveolars

x In the pronunciation ofto the tip of the tongue

touches the alveolar ridgex We call this sound linguo -alveolar or apico-

alveolar


20/32

Articulation

x bi-labial

x labio-dental

x interdentalx linguo-alveolar (or

apico-alveolar)

x put

x throughx to


21/32

Palate

x The roof of the mouth is called the palate

x It begins just behind the dorsum of the tongue

and ends above the dorsum of the tonguex Front part since it is hard is callled the hard

palate

x Soft part-located at rear of mouth is called thevelum


22/32

Both hard and soft parts of velum

are points of articulationx Sounds articulated at hard palate are

calledpalatals

x Sounds articulated at the velum are calledvelars


23/32

Uvula

x Refers to the small flexible flap whichhangs

from the back of the velum

x The dorsum(back) of the tongue contactsthe uvula to produce dorso-uvular sounds

x In English the uvula is not an important

point of articulationx In French the r has a uvular trilled sound


24/32

Pronounce the word kit

x The dorsum of the tongue touches the

velum

x We call this a dorso-velar sound


25/32

Identify the following points of

articulation on the diagramx Alveolars

x Dentals

x Labials

x Velars

x

Uvulars


26/32

Maximum Closure

The point of maximum closure in oral

cavity during the production of aspeech sound is also referred to as

the point of articulation


27/32

Impossible sounds

x Apical-uvular

x Labio-palatal


28/32

Pharyngeal Sounds

x In Arabic ,the root of tongue comes in

contact with the back wall of the pharynx

x We call these sounds pharyngeals

x We have no pharyngeal sounds in English


29/32

Nasal Sounds

x Unlike the oral cavity, the size and shape of the

nasal cavity are fixed

x They cannot be modifiedx The nasal cavity is separated from the oral

cavity by the palate

x

Oral sounds resonate in the oral cavityxNasal sounds resonate in the nasal cavity

x m,n, and


30/32

Nasal Quality

x Sounds have a nasal quality if they are

resonated in the nasal cavity

x When the velum is raised the passage intothe nasal cavity is closed

x When the velum lowers a slight nasal

quality will occur


31/32

Pronounce no

x The apex of the tongue touches the alveolar

ridge

x It will register an apico-alveolar sound

x Because the velum drops it resonates in the

nasal cavity

x We call the sound apico-alveolar nasal


32/32

Identify the articulator and point

of articulation for the followingx Lower lip upper lip

x Lower lip upper teeth

x Apex (of tongue)upper teeth

x Apex (of tongue)

alveolar ridge

x Apex(of tongue)

alveolar ridge

x Bi-labial

x Labio-dental

x Interdentalx apico-alveolar

x apico-alveolar nasal
