THE SPEAKING PROCESS

ENG 132

Page 2: Speech mechanism

Stages of the Speaking Process:

Breathing stage

Phonation stage

Resonation stage

Articulation stage

Page 3: Speech mechanism

BREATHING STAGE

Page 4: Speech mechanism

Breathing, which is primarily concerned with

maintaining life, is secondarily a force

assisting in vocalization. It consists of two phases

--- inhalation and exhalation.

Page 5: Speech mechanism

LUNGS• Serve as the

reservoir of air• As you inhale, fill

the lungs comfortably in preparation for speaking.

Page 6: Speech mechanism

Diaphragm• A large sheet of

muscle separating the chest cavity from the abdomen

• Forms the floor of the chest and the roof of the abdomen

• Gives pressure to the breath stream

Page 7: Speech mechanism

BREATHING EXERCISE:

• 1. Sit up straight. Exhale.• 2. Inhale and, at the same time, relax the belly muscles. Feel as though the

belly is filling with air.• 3. After filling the belly, keep inhaling. Fill up the middle of your chest. Feel

your chest and rib cage expand.• 4. Hold the breath in for a moment, then begin to exhale as slowly as

possible.• 5. As the air is slowly let out, relax your chest and rib cage. Begin to pull

your belly in to force out the remaining breath.• 6. Close your eyes, and concentrate on your breathing.• 7. Relax your face and mind.• 8. Let everything go.• 9. Practice about 5 minutes.

PHONATION STAGE

Page 9: Speech mechanism

Phonation takes place when voice is produced in

speaking as the expiratory air stream from the lungs

goes up through the trachea or windpipe to the larynx.

Page 10: Speech mechanism

Larynx• Principal organ of

phonation• Found at the top

of the trachea• Protuberance is

known as the “Adam’s apple”

Page 11: Speech mechanism
Page 12: Speech mechanism

Vocal Cords• A pair of bundles

of muscles and cartilages• Open and close

at various degrees

Page 13: Speech mechanism

Trachea• Also known as

windpipe• Passageway of

air going up from the lungs

Page 14: Speech mechanism

PHONATION EXERCISE

• Think about blowing out birthday candles.

• Begin to blow and then turn the breath into an "ooo" sound on a comfortable pitch. Feel the tone begin in the breathing muscles.

• Repeat

Page 15: Speech mechanism

RESONATION STAGE

Page 16: Speech mechanism

The voice produced in phonation is weak. It

becomes strong and rich only when amplified and modified by the human resonators.

Resonation is the process of voice amplification and

modification.

Page 17: Speech mechanism

Pharynx• Common passageway

for air and food• Located behind the nose

and mouth and includes the cavity at the back of the tongue

• Divisions of the pharynx:– Nasal pharynx– Oral pharynx– Laryngeal pharynx

Page 18: Speech mechanism

Nose• Consists of the external and

internal portions• Nostrils – openings of the

external nose• Nasal cavity – internal nose;

directly behind the external nose through which the air passes on its way to the pharynx

• Septum – divides the external and internal nose into two separate passageways

Page 19: Speech mechanism
Page 20: Speech mechanism

Mouth• Divided into the vestibule

and the oral cavity proper

• Vestibule – felt by placing the tongue tip outside the teeth but inside the lips

• Oral cavity – felt by retracting the tongue, closing the jaws and moving the tongue about

RESONATION EXERCISE: Pronounce the letters according to its size. (biggest letters mean

loudest sounds)

RESONATION EXERCISE: Read the black syllables softest and the red syllables

loudest.

ARTICULATION STAGE

Page 26: Speech mechanism

Articulation occurs when the tone produced in the

larynx is changed into specific sounds. This is the result of the movement of the articulators towards

the points of articulation.

Page 27: Speech mechanism

Lips• Highly flexible • Can be moved

into numerous positions essential to articulation

Page 28: Speech mechanism

Teeth• Serve as

important surfaces in articulation• Embedded in the

alveolar ridge or gum ridges of the oral cavity

Page 29: Speech mechanism

Dome• Also known as the

hard palate• Bony roof of the

mouth• Serves as an

important surface against which the tongue makes contact

Page 30: Speech mechanism

Uvula• Small nub on the

lower border of the soft palate• Movable tip at

the midline of the free border of the soft palate

Page 31: Speech mechanism

Velum• Also known as the

soft palate• Separates the nasal

pharynx from the oral cavity

• A flexible curtain attached along the rear border of the hard palate

Page 32: Speech mechanism

Tongue• Flexible organ consisting

of muscles, glands and connective tissues

• Parts of the tongue:– Apex or tip– Blade

• Front• Center• Back• root
