The Role of Phonetics in English

What is Phonetics?

English phonetics helps learners pronounce words correctly by helping them recognize and articulate the language’s sounds. It includes the study of sound production, perception, and transmission, all of which are crucial for clear language understanding and efficient communication. In order to enable clear and understandable spoken English, phonetics helps students acquire the abilities necessary to identify, produce, and distinguish between English sounds.

Branches of Phonetics

Phonetics is the study of speech sounds. It is broadly categorized into three main branches: Articulatory Phonetics, Acoustic Phonetics and Auditory Phonetics.

Articulatory Phonetics
Articulatory phonetics is a branch of phonetics that focuses on the physical aspects of speech production. It looks at the movements and postures of the lips, tongue, jaw, vocal cords, and other speech organs as well as how the human vocal tract produces and articulates speech sounds. Three processes go into making a speech:
-Initiation: Causing the vocal tract to fill with air.
-Phonation: Airflow alteration as it goes through the larynx.
-Articulation: The manipulation of airflow to produce specific sound kinds.

Articulatory phonetics refers to the features of phonetics that examine how the vocal tract’s organs produce spoken sounds.

1. Voice:
There are voiced and voiceless sounds in English. Depending on the behavior of the vocal folds during the production of a spoken sound, a sound falls into one of these categories.

Voiced: Voiced sounds are those that, when generated, cause vibrations in the vocal folds. Examples of voiced sounds are /b,d,v,m/.
You should feel a vibration if you lay two fingers on either side of the front of your neck, slightly below your jawbone, and make a sound. This indicates that a vocal sound is Present.
Voiceless: Sounds generated without vocal fold vibration are referred to as voiceless sounds. Examples of voiceless sounds in English are /s,t,p,f/.

2. Place:
The several portions that make up the vocal tract are essential to the creation of speech. These parts, known as articulators, are what enable speech sounds. They fall into two categories.

When a spoken sound is produced, the articulator that advances toward another articulator is known as the active articulator. To create a vocal tract closure of some kind, this articulator travels toward another articulator.

The articulator that stays motionless while producing a speaking sound is known as a passive articulator. The active articulator frequently travels in this direction.

-Bilabial: Both the upper and lower lips are used in bilabial sounds. The lips make efficient constriction when they come into contact with one another during the production of a bilabial sound. /p,b,m/ are bilabial sounds in English.

-Labiodental: Labiodental sounds are produced when the vocal tract is effectively constricted by the contact of the upper teeth (dental) and lower lip (labial). In English, labiodental sounds include /f,v/. There are two categories of labiodental noises.

-Dental: To produce dental sounds, the active articulator (tip of the tongue) must make contact with the upper teeth to create a constriction. In English, some examples of dental sounds are /θ, ̰/. The term “interdental” refers to a sound made when the tongue is between the upper and lower teeth.

-Alveolar: It’s helpful to identify the alveolar ridge itself. You can feel a bony ridge if you put your tongue right behind your teeth and move it around. The alveolar ridge is the term for this. In order to create an effective constriction in the vocal tract, the front part of the tongue must make contact with the alveolar ridge. In English, alveolar sounds include /t,d,n,l,s/.

-Postalveolar: Sounds produced ‘post’, or a little distance behind, the alveolar ridge. When your tongue’s blade makes touch with your mouth’s post-alveolar region, you make a postalveolar sound. In English, post-alveolar sounds include /˃, ʒ, and /.

-Palatal: The large, fleshy portion of your tongue is used to produce palatal sounds. To create a useful constriction, the tongue body lifts upward toward the hard palate, or the dome-shaped roof of your mouth. In English, the palatal sound /j/ is an example.

-Velar: Velar sounds are produced when the tongue’s dorsum, or back, lifts in the direction of the soft palate, which is situated behind the roof of the mouth. The velum is the name given to this sensitive palate. The interaction between these two articulators therefore results in the formation of an effective constriction. In English, velar sounds include /k,g ŋ /.

3. Manner:
The method a sound is produced, as opposed to where it is produced, is referred to as its style of articulation. The methods used to create different sounds vary. Depending on the particular sound kind, the air flow varies as the articulators are brought closer to one another.

-Stop articulations:
Sounds that need the vocal tract to completely close are known as stop articulations. When two articulators meet to stop air from escaping between them, the closure is created. A stop articulation’s classification might be based on the type of airflow it involves. There are two types of airflow: nasal (nasals) and oral (plosives). To explain briefly:

-Plosives: Plosives are vocal sounds produced by the oral (vocal) tract that are completely closed. A plosive sound causes the velum to rise, keeping air from exiting via the nasal cavity. Phonological plosives in English are /p,b,t,d,k,g/. Plosives are sometimes known as “maintainable stops” since they can be held for extended periods of time.

-Nasals: When it comes to sounds being produced in the oral (vocal) tract with a complete closure, nasals and plosives are comparable. On the other hand, during nasal noises, the velum is depressed, allowing air to exit through the nasal cavity. In English, there are three nasal sounds: /m, n, ŋ/.

-Fricatives: By bringing the active and passive articulators closer together, or narrowing their gap, fricative sounds are generated. As a result, as airflow moves between the two articulators that produce a fricative sound, it becomes turbulent. English fricatives include the following sounds: /f,v, θ,ð, s,z, ʃ,ʒ /.

-Approximants: Shortening the distance between the two articulators produces approximate sounds. However, the distance isn’t broad enough to produce turbulent airflow, unlike fricatives. The four approximate sounds in English are /w,j,r,l/.

Vowels: To characterize vowels, we employ a distinct specification. We examine the tongue’s vertical and horizontal positions as well as the location of the lips. Free airflow down the midline of the vocal tract is used to produce vowels. They are typically produced frictionlessly and with voice.

1. Vertical tongue position (close-open): Closeness of the tongue to the roof of the mouth during the production of a vowel is known as the vertical tongue position (close-open). The tongue is assigned the label “close” if it is closed.
2. Horizontal tongue position (front, mid, back): When a vowel is formed, the location of the tongue in the vocal tract—either “at the front” or “at the back”—is referred to as horizontal tongue. The tongue receives the label front if it is in the front of the mouth, the label mid if it is in the middle of the mouth, and the label back if it is in the back of the mouth.
3. Lip position: The location of the lips during the production of a vowel is what lip position is implied to be. Neutral, wide, or rounded lips are all possible
-Monophthongs: Monophthongs are vowels that are produced by a relatively stable tongue position.
-Diphthongs: Vowels that have diphthongs are those in which the tongue shifts position within the mouth. They can be thought of as beginning with one vowel and ending with another.

Acoustic Phonetics
The study of acoustic phonetics examines the physical characteristics of speech and seeks to analyze the sound waves that are produced by speech at different frequencies, amplitudes, and durations.

Using a waveform as a guide, we can examine the acoustic characteristics of speech sounds. Plotting pressure fluctuations on a waveform reveals the compressed and rarefied air particles, generating outward-moving sound waves. An example of air pressure variations and how air particles oscillate—or move rhythmically in one direction—when humans sense music can be found by striking a tuning fork.

Auditory Phonetics
Within the larger discipline of phonetics, the study of auditory perception of speech sounds by humans is known as auditory phonetics. It delves into the intricate mechanisms by which the ear perceives and processes sound waves, as well as how the brain decodes these signals into coherent speech.
