• Voicing is a complex phenomenon • We articulate thousands of sounds, unconscious of
their process of articulation.• Humans are privileged ones as compared to their primates.• Humans have a vocal apparatus that is apt for
articulation of discrete speech sounds • Tongue• Teeth• Lips
INTRODUCTION

THE LARYNX• In the production of speech sounds the larynx has
many important functions, but before we can look at these functions we must examine its anatomy and physiology, how it is constructed and how it works.
• Larynx is in the neck.• Its main structure is CARTILAGE.• Larynx is made up of two cartilages these cartilages
are hollow and are attached to the top of the TRACHEA.
• When we breath the air passes through the trachea and the larynx.

• These are two thick flaps of muscles rather like a pair of lips, the ex-name for these is vocal cords.
• At the front, the vocal folds are joined and fixed to the inside of the thyroid cartilage. At the back they are attached to a pair of small cartilages called the Arytenoids Cartilages.
Vocal Folds

Different positions of Vocal FoldsWIDE APART• The vocal
folds are wide apart for
normal breathing
and usually during voiceless
consonants like
p, f, s

Different positions of Vocal Folds
Narrow Glottis
• If air is passed through the glottis when it is narrowed, the result is a fricative sound for which the symbol is /h/. The sound is not very different from a whispered vowel. It is called a voiceless Glottal Fricative.
![Page 9: Rules of voicing](https://reader030.vdocuments.site/reader030/viewer/2022012305/586fd87c1a28ab18428b5603/html5/thumbnails/9.jpg)
• when the edges of vocal folds are touching each other are nearly touching, air passing through the glottis will usually cause vibration.
• This opening and closing happens very rapidly and is repeated regularly between two and three hundred times persecond in woman’s voice and about half that rate inman’s voice.

Vocal folds Tightly closed the vocal folds can
be firmly pressed together so that air cannot pass between them.
This position is a glottal stop or glottal plosive.

Respiration and Voicing
When air is moved out of the lungs we say there is an aggressive pulmonic air stream.
All speech sounds are made with some movements of air.
The lungs are like sponges and they are contained within the rib cage.
Lungs expanded with the result they take in more air.
Speech sounds are produced by the expelling of air at the rest position of rib cage.

Different variations in the vocal folds
We produce voicing with high intensity for shouting, for example, and with low intensity for speaking quietly.
Variations in intensity

If the vocal folds vibrate rapidly, the voicing is at high frequency; if there are fewer vibrations per second the frequency is lower.
Variations in Frequency

Different sounding voice qualities are produced.
such as those are harsh, breathy, murmured or creaky.

PLOSIVES
A plosive is a constant articulation that is produced by stopping the airflow using the lips, teeth, or palate, followed by a sudden release of air.

Closing phase
P, t, k (No voicing takes place) b, d , g (No voicing takes place)
Compression phase
P , t , k (No voicing takes place) b , d , g (voicing takes place during the entire
compression phase)
1. Initial position (c v)
![Page 23: Rules of voicing](https://reader030.vdocuments.site/reader030/viewer/2022012305/586fd87c1a28ab18428b5603/html5/thumbnails/23.jpg)
1. Initial position (c v)
Release phase
p , t , k (Release of p, t, k is followed by an audible plosion)
b , d , g (Release of b, d, g is followed by a weak plosion)
Post Release phase p , t , k (Air escapes through vocal folds, making
a sound like h. ”aspiration” )b, d ,g (there is no aspiration and voicing
continues)
![Page 24: Rules of voicing](https://reader030.vdocuments.site/reader030/viewer/2022012305/586fd87c1a28ab18428b5603/html5/thumbnails/24.jpg)
Aspiration
In initial position b , d ,g cannot be preceded by any consonant
In initial position p , t ,k can be preceded by s and in such a situation p , t ,k will be un aspirated (spy, store, ski)
Difference in the initial position

2. Medial position (v c v)
We can say that a medial plosive may have the characteristics either of final or of initial plosives.
![Page 26: Rules of voicing](https://reader030.vdocuments.site/reader030/viewer/2022012305/586fd87c1a28ab18428b5603/html5/thumbnails/26.jpg)
In final position b , d ,g have little voicing and if there is voicing it is at the beginning of compression phase.
In final position p , t , k are obviously voiceless.
In final positions the plosion following the release of p,t,k & b, d, g is very weak and often not audible.
3. Final position (v c)
