THE ARTICULATORY SYSTM

 How do we produce sounds?

 Think for a minute about how people produce sounds. Say a few words and concentrate on what’s happening inside your mouth. The movements of your tongue, lips, and jaw are incredibly quick, delicate, and complex—just as complex as the movements of an Olympic gymnast or a surgeon’s hands. When you think about it, it’s a miracle that anybody can talk at all. So how do we produce speech sounds? When we speak, we push air out of our lungs, up through our throat, and out our mouth or nose. The vibration of our vocal cords, along with movements of our tongue and lips, changes the airflow and produces different sounds. Even a slight change in the position and movements of these parts can make a perceptible change in the sound that is produced.

Process of Speech Production

  • Tone generated by larynx is modified, through resonating structures, and is shaped into speech sounds by several structures (tongue and lips). The shaping of speech sounds is know as Articulation
  • Pharynx - sounds travels through the nasal, throat and mouth cavities known as the pharynx
    • laryngopharynx - starts above the larynx
    • oropharynx - laryngopharynx connected oropharynx
    • nasopharynx - oropharynx connected to nasoharynx, ends where 2 nasal cavities begin
  • Laryngopharynx and oropharynx add resonance to the sounds from the larynx.
  • Nasopharynx adds resonance to nasal sound s(m, n, ng). Nasal cavity normally is closed.
  • Movement of the tongue, lips, and the larynx will change the shape of the vocal tract and in turn modify the sound emanating from the larynx. During consonant production, the tongue is sometimes used to momentarily occlude the vocal tract for the production of stop sounds like /t/, /d/, /k/, and /g/. Production of sounds like /s/ and /sh/ require the tongue to form a constriction in the vocal tract that will produce noise when air is passed through the constriction.

The articulatory system

The lips are used in the production of several consonant sounds: /p/, /b/, /m/, /w/, /f/, and /v/. The way we move our lips—making them rounded, unrounded, or stretched a bit wide—also affects the sounds of vowels. The teeth are used when we say the consonant sounds /f/ and /v/, with the upper teeth touching the lower lip, and also /θ/ and /ð/, with the tip of the tongue touching the upper teeth. The alveolar ridge is the slightly rough area just behind the top teeth. It can also be called the tooth ridge or the gum ridge. The tongue touches or almost touches the alveolar ridge when we say the sounds /t/, /d/, /s/, /z/, /l/, and /n/. The hard palate is the hard part at the top of the mouth, beginning just behind the alveolar ridge. It can also be called the roof of the mouth. When you close your mouth, your tongue is probably flat against your hard palate. The tongue touches or almost touches the hard palate when we say the sounds /ʃ/, /ʒ/, /ʧ/, /ʤ/, and /y/. The soft palate is the softer part of the roof of the mouth, farther back than the hard palate. It is also called the velum. If you touch the roof of your mouth with your tongue and then keep moving your tongue 3 farther back, you’ll find that softer area. The back of the tongue touches the soft palate when we say the sounds /k/, /ɡ/, and /ŋ/. The tongue is involved in producing almost all the sounds of English, both consonants and vowels. We can also refer to different parts of the tongue: the tip of the tongue, the blade of the tongue, and the back of the tongue. The lower jaw moves up and down to allow the mouth to open and close. Its movement also helps the tongue move to higher or lower positions, and to makes the space inside the mouth bigger or smaller. All of these movements have a great influence on the sounds we produce. The nasal cavity is the space inside the nose where air passes in and out when we breathe through our nose. It can also be called the nasal passage. This area is important in producing the nasal sounds /m/, /n/, and /ŋ/. For these sounds, the air stream moves up and out through the nose instead of the mouth


Teach about the articulatory system

It is important for students of all ages to know the parts of the mouth and how they move when they make sounds. It is much less important for them to memorize the names of the parts of the articulatory system, whether in English or in their mother tongue. We can use tools, models, and illustrations to help students of all ages understand the articulatory system. For example:

• Have students look in a mirror to see how their mouths move, whether or not their lips are rounded, and how open their mouths are. They can compare these things to a picture or the teacher's example.
• Have students touch their throats to feel the vibration of the vocal cords.
• Use a dental model (a set of giant teeth like dentists to show children how to brush their teeth) to show students 4 what is happening inside their mouths. It is much easier to show students where the alveolar ridge is on a model, for example, than to try to get them to look into the teacher's mouth. (It's dark there!)
• Diagrams of the vocal tract, such as the ones we have seen in this chapter, also give
students a visual image of the position of the articulators during speech. This type of diagram is often called a "Sammy" diagram (I don't know why) or a sagittal diagram.
section diagram. However, these diagrams are sometimes difficult for students to understand and connect with reality, especially for younger students.




CONSONATS SOUNDS: VOICED AND VOICELESS

 Phonetics (who study the sound of the human voice) divide consonants into two types: voiced and unvoiced. Voiced consonants require the use of the vocal cords to produce their characteristic sounds; deaf consonants do not. Both types use the breath, lips, teeth, and upper palate to further modify speech. This guide introduces the differences between voiced and voiceless consonants and gives you some tips for using them.

Voiced and deaf consonants

 It is important to make a distinction when talking about consonant sounds. Consonant sounds can be voiced or unvoiced.

Put your hand to your throat and say the word "P ick". Now I saw the word "b ig". Did you notice something different? When you said the word "big", your vocal chords should have vibrated. This is because / b / is a voiced consonant. / p / is a voiceless consonant.


Voiced consonants

The vocal cords, which are actually mucous membranes, run the length of the larynx at the back of the throat. By contracting and relaxing while speaking, the vocal cords modulate the flow of air expelled from the lungs.

An easy way to determine if a consonant is voiced or not is to place a finger on the throat. As you speak a letter, feel the vibration of your vocal cords. If you feel a vibration, the consonant is voiced. These are the voiced consonants: B, D, G, J, L, M, N, Ng, R, Sz, Th (as in the word "then"), V, W, Y and Z. But if the consonants are just individual letters, what are Ng, Sz, and Th? They are common sounds that are produced by combining the two consonants phonetically.

what is Voiced?

A simple explanation of voiced consonants is that they use the voice. This is easy to test by putting your finger on your throat. If you feel a vibration the consonant is voiced. Here is a list of some voiced consonants. Pronounce each consonant sound (not the letter) and feel the vibration of your vocal chords.

Here are some examples of words that include voiced consonants:

traveled

gloves

shells

started

changed

wheel

lived

Dreams

interchanged

balloons

The telephones

listened

organized

Voiceless consonants

Deaf consonants do not use the vocal cords to produce their harsh and percussive sounds. Instead, they are loose, allowing air to flow freely from the lungs to the mouth, where the tongue, teeth, and lips come together to modulate sound. These are the voiceless consonants: Ch, F, K, P, S, Sh, T and Th (as in "thing").

What is Voiceless?

Voiceless consonants do not use the voice. They are percussive and use hard sounds. Once again, you can test if a consonant is voiceless by putting your finger on your throats. You will feel no vibration in your throat, just a short explosion of air as you pronounce. Pronounce each of these consonant sounds and feel NO vibration in your throat.

Common words that use them include:

washed

coats

Viewed

books

seating

fallen

carts

ARTICULATORS OF SPEECH SOUNDS

 ARTICULATORS OF SPEECH SOUNDS 


ARTICULATORY ORGANS

Speech sounds are basically a stream of air that in most cases originates in the lungs, passes through the larynx, the mouth and finally exits. The articulatory organs are responsible for affecting the air flow and modifying it giving you the different nuances that distinguish between a speech sound and other. The articulatory organs are divided into two groups: Active and Passive.

- Active Articulators (mobile)

Active articulators are parts of the vocal apparatus that move to cause a
obstruction (partial or total) and affect the movement of the air stream. The organs
assets are:
1. Tongue: apex, fore, middle, back, and root.
2. Lower lip
3. Vocal cords
4. Soft palate (Always used in combination with another articulator)


- Passive Articulators (immobile)

Passive articulators are the parts of the body that active articulators touch or come close to cause a total or partial obstruction and thus affect the movement of the air stream. Passive articulators are:

1. Upper lip 2. Teeth: the upper incisors and their posterior aspect. 3. Alveoli 4. Postalveolar region: posterior to the alveoli and anterior to the arch of the palate Lasted. 5. Hard palate 6. Soft palate (anterior soft palate) 7. Uvula 8. Posterior side of the pharynx


ARTICULATION ZONES

when we produce consonant sounds the air passage is totally or partially obstructed. This obstruction occurs when an active articulator approaches or makes contact with a passive articulator. TO This relationship (approach or overlap) between both articulators is called joint area. For example, some sounds, like p, are called lipsticks because they articulate with the lips. Others, like you, are called dental because articulate with the tip of the tongue in contact with the teeth. Other areas of articulation are the alveoli (there are produced sounds such as l, r, etc.), the different palate areas, etc.

PHONETICS AND ITS BRANCHES

 PHONETICS AND ITS BRANCHES 

The main branches of phonetics are the following:

1)  Articulatory phonetics

The organs involved in the production of sounds: the speech apparatus.
The air stream, which comes from the lungs, undergoes a series of transformations when it passes through the speech apparatus and becomes sound. The set of organs involved in phonation are:

Respiratory organ or infraglottic cavities: they are formed by the organs that function in respiration:

Lungs, bromchiae, trachea. The lungs perform two movements: inspiration and expiration. The air contained in the lungs reaches the bronchi and from there to the trachea.

Speaking organ or laryngeal cavity:

The larynx is made up of four cartilages: cricoid, thyroid, and two arytenoids. The action of the vocal cords produce the 1st classification of articulated sounds:

If the vocal cords vibrate: the sound is loud
If the vocal cords do not vibrate: the sound is muffled

Supraglottic cavities:

As the air stream passes through the larynx it reaches the pharynx where another division of sounds is made according to the action of the soft palate.

-Articulated sounds: oral
-Consonant sounds: nasal
-Vowel sounds: nasal


2) Acoustic phonetics

It is the study of phonetics from the point of view of sound waves. It deals with the scientific measurement of the sound waves that are created in the air when we speak. Just as we attribute articulatory features to phonemes, we can attribute acoustic features to sounds: vowel / non-vowel and consonant / non-consonant, compact / diffuse voiced / deaf, nasal / oral, interrupted / continuous, strident / matte, severe / sharp. These measurements are reflected in spectrograms, in which the different formants into which the sounds are decomposed are reflected.

3) Auditory phonetics

consider phonetics from the point of view of the listener (receiver). Hearing begins in the ear and ends in the brain. - Hearing aid

PHONETICS AND PHONOLOGY

PHONETICS AND PHONOLOGY

PHONETICS

Phonetics and phonology are sister linguistic disciplines, which address human language or verbal language, but do so from two different and complementary points of view.

Phonology is interested in language as a mental and social system of signs, that is, considering it in the abstract, as a mental system that associates signs with specific sounds. On the other hand, phonetics is only interested in the specific way of making these signs by means of the speech apparatus.

Put more simply: phonology studies phonemes, that is, the mental traces of sound that serve to build the complex system of a language. On the other hand, phonetics studies phones, that is, the ways in which different groups of speakers of a language produce the sounds that allow them to communicate through a language.

Thus, while phonology is abstract, collective and immaterial, phonetics is concrete, individual and material. The same phoneme can be pronounced very differently by several individuals who speak the same language, depending on their sociocultural group and their individual physical abilities for pronunciation. All this is of interest to phonetics, but not to phonology.


Phonetics functions

Phonetics has numerous practical applications and functions, such as:

The study of the speech mode of the users of a language, in order to understand the dialect or sociolectal differences that exist in a community of speakers of a specific language.
The registration of the forms of speech of the users of a language, to be able to study the way in which the language changes over time, as the use is imposed on the norm.
The study of the mechanisms of sound production in general, to help people who have linguistic difficulties or who require for one reason or another phonetic therapy or speech therapy.
The understanding of the modes of articulation of the same language by the different speaking communities that use it, for voice recognition and artificial intelligence technologies.

PHONOLOGY

Phonology, on the other hand, studies the phonic elements, or units, of a language from the point of view of their function.
Phonemes, then, are the smallest phonological units into which a phonic set can be divided, their main characteristic is the ability to differentiate meanings; for example, it is not the same expensive as car or that cabo, they are all within the ca _ o field, but their meaning changes when the phonemes change.

The two components used to make consonant sounds are:

1) The place of articulation (the ‘where’ the sounds are made)

2) The articulators (the ‘what’ are used to make the sounds)

Example:

The two lips (the articulators) meet to form the bilabial sounds of /b/ and /p/.

The tip of the tongue – the articulator – meets with the alveolar ridge – the place of articulation (which is right behind the front teeth) – in order to form the alveolar sounds of /d/ and /t/.

There are seven places of articulation used to distinguish consonant sounds


Places of Articulation

- Bilabial (or ‘two lips’): Produced with the two lips: /b, p, m, w/ (as in ‘     buy, pie, my, and wool’).



Labiodental (or ‘lip and teeth’): Produced with the upper teeth and inner lower lip: /f, v/ (as in ‘feel and veal’)


Interdental (or ‘between teeth’): Produced with the tongue tip on or near the inner surface of the upper teeth: /θ/, /ð/ (as in ‘thick and then’)



Alveolar (or ‘behind teeth’): Produced with the tongue tip on or near the tooth ridge: /t, d, s, z, n, l/ (as in ‘to, do, zoo, new, and light’).


Palatal (or ‘top middle of mouth’): Produced by the body of the tongue touching the roof of the mouth (in the palatal area): /ʃ, ʒ, ʧ, ʤ, r, j-y/ (as in ‘shin, genre, chef, judge, red, and yes’).

**Note that the /ʃ, ʒ, ʧ, ʤ/ sounds are all pronounced with the front of tongue places on the top of mouth while the /j-y/ one is pronounced with more of the rear of the tongue placed a bit further back on the palate than /ʃ, ʒ, ʧ, ʤ/. Finally, the /r/ sound is made with the sides of the tongue placed on the sides of the roof of the mouth pressed against the teeth.

Velar (or ‘top of throat’): Produced with the tongue body on or near the soft palate: /g, k, ŋ/ (as in ‘go, kite, and bang’)

Glottal (or ‘from the throat’): Produced by air passing from the windpipe through the vocal cords: /h/ (as in ‘hi’).

VOWEL SOUND IN THE VIETOR TRIANGLE, DIPHTONGS AND THIPHTHONGS

VOWEL SOUND IN THE VIETOR TRIANGLE, DIPHTHONGS AND TRIPHTHONGS

1.           VOWEL SOUND IN THE VIETOR TRIANGLE

A Victor Triangle is a schematic representation of vowel sounds, created by Wilhelm Vietor (1850-1918, German philologist and phonetician).
"is
a vowel triangle which shows the differences among the vowel sounds in English and their relative positions on the tongue" (Grinchenko, 2006)

Vowels are produced with at least a part of their vocal tract obstructed.

contains two axes:

      

a. horizontal axis – from front to

      (front, center, back)

      roof of the mouth

b. vertical axis – from the floor to the

       (high, mid, low)

A vowel diagram or vowel chart is a schematic arrangement of the vowels. Depending on the particular language being discussed, it can take the form of a triangle or a quadrilateral.

Vertical position on the diagram denotes the vowel closeness. With close vowels at the top of the diagram, and horizontal position denotes the vowel blackness, with front vowels at the left of the diagram. Vowels are unique in that their main features do not contain differences in voicing, manner, or place (articulation).

Vowels differ only in the position of the tongue when voiced. The tongue moves either vertically and horizontally within the oral cavity.


2.      DIPHHONGS

His words diphthong comes from the Latin diphthongs, a word that at the same time has its origin in a word derived from Greek language. The term refers to the union or the combination of a pair of adjacent vowels that are expressed in the same syllable. It is a vowel that has two different targets (Briceño, 2017).

2.1.            WHAT IS THE DIPHTHONG?

are those sounds which combine two vowel sounds and which blend them into one within a syllable ,   a type of sound chain that is formed by the articulation of two adjacent vowels followed by each other without any interruption, generating a smooth transition that characterizes the timbres of each vowel. (Estrella, 2020)

The diphthong is the union that occurs between two different vowels that are placed continuously within the same syllable and may be formed by an open vowel such as e, e, o, and a closed vowel such as i and u. The process by which one vowel sound moved to another is known as gliding, this is the reason why a diphthong is also called “gliding vowel”. Another types of names to refer to this type of sound are compound vowels, complex or moving vowels. It is important to mention that the sound change that converts a single vowel into a diphthong is known as diphthongization.

 For example:

The sound /ei/ in play has two vowel sounds, /e/ and /i/.

Maybe the most important  is that they are not formed by two simple vowels together, but one long vowel where the pronunciation changes since the beginning to the end, in other words, the pronunciation changes completely at the end of the word. The most common diphthongs are said to be /ow/, /ou/, /oy/ and /oi/ as in bow, ground, toy and coin

2.2.          CHARACTERISTICS OF ENGLISH DIPHTHONGS

Their main characteristics are the following:

        Both vowels have to be lax.

        The first one is the most important in terms of stress. This means that, for example, in diphthong [aɪ], sound [a] is much longer and stronger than sound [ɪ].

        Vowels pronunciation take place through a glide, that is, through a continuous and very smooth movement from the first vowel to the second, in other words, they are not articulated distinctly

        the diphthongs must be envisaged as resulting from the tongue and lip movement from an initial position to a position approaching the position of the second sound element.

2.3.            Types:

We have two different types of diphthong, and these can be:

ü Closing: this type of diphthong is the one in which the last vowel is near-high. As the two vowels need to be lax, there are only two different possibilities [ɪ] and [ʊ].

ü Centering: these ones ends in a vowel [ə] (schwa).

It is important to mention that diphthongs [aɪ], [eɪ], [ɔɪ], and [aʊ] can be found in British and American English, and [əʊ] only in British.

Most common diphthongs found in American English (Briceño, 2017)

/eɪ/: It has a Long A sound

This type of diphthong is very similar to the long A sound. The correct way to pronounce it is as a long A sound sliding into a long E sound. It is important to understand that some dialects pronounce the long A sound as one single sound. There is also the case where is pronounced as two vowel sounds. Some people who has a southern accent, mainly from the south part of the United States will stretch out the diphthong more. Some examples are:

Day, may, clay, away, lay, play, eight

/aɪ/: This type of diphthong is pronounced as a long I sound sliding into a long E sound.
The sound of this diphthong can vary from one dialect to another one. In some places the long I sound is pronounced in the words as one single sound. Some dialects pronounce the vowel sound more like the “AH” sound you would here in “ball”. Or it can also be pronounced as two vowel sounds. Some examples of words with this type of diphthong are:

Sky, try, fry, pie, cry, tie, why, eye

  /ɔɪ/: This one is pronounced as a long O sound, in this case, the sound quickly slides into a long E sound. Some examples of this type of diphthong are:

           Joy, annoy, enjoy, ploy, soil, boil

     /ɪə/: It is pronounced as a long E sound sliding into an Ur sound. The examples are:

  Pier, hear, steer, clear, fear

     /eə/: This diphthong is pronounced as a long A sound sliding into a U sound. Examples:

          Beard, hair, fair, stairs, pair, wear, where

/aʊ/: Is pronounced as a short A sound sliding into an “oo” sound. Some examples of this type of diphthong are the following:

            Brown, cow, how, frown, now, wow

/əʊ/: This diphthong is frequently used and only pronounced as a single long O sound. It is important to remember that this type has a long O sound sliding into an “oo” sound. Some examples are:

           Yellow, coat, float, though, toe, no, low, although.

/ʊə/:  This diphthong is pronounced as a log O sound sliding into a U sound.  For example: tourist, poor, moor.

 

Examples of Diphthongs:

ü   /eɪ/ as in day, pay, say, lay

ü   /aɪ/ as in sky, buy, cry, tie

ü   /ɔɪ/ as in boy, toy, coy or the first syllable of soya

ü   /ɪə/ as in beer, pier, hear

ü   /eə/ as in bear, pair, and hair

ü   /ʊə/ as in tour, poor or the first syllable of tourist

ü   /əʊ/ as in oh, no, so, or phone

ü   /aʊ/ as in all the words of “How now brown cow”

ü    /ɪə/ hear  /hɪə/

ü    // hair  /heə/

ü    /ʊə/ poor  /pʊə/ 

2.      TRIPHTHONGS

Is the union of three vowels (letters or sounds) pronounced in one syllable (as in fire), More example sentences, 'Diphthongs and Triphthongs do not come into the picture at all, ''Words such as course and force are sometimes realized with a triphthong /, especially among older speakers. (wikipedia, 2020)

 A Triphthongs is a glide from one vowel to another and the to a third, all produced rapidly and without interruption. For example, a careful pronunciation of the word ‘hour’ begins with a vowel quality similar to ‘ɑ:’, goes on to ‘ʊ’ then ends in ‘ə’.

It says /aʊə/

2.1.            Triphthong Word Phonetic Transcription

A combination of three vowel sounds in a single syllable forming a simple or compound sound: also, a union of three vowel characters representing together a single sound: a trigragh: as eye. Ieu in adieu. Eau in beau, are examples of Triphthongs.

 

5 closing diphthongs with ‘ə’ added on the end.

         eɪ + ə = eɪə. as in layer, player

         aɪ + ə = aɪə. as in lire, fire

         ɔɪ + ə = ɔɪə, as in loyal, royal

         əʊ + ə = əuə, as in lower, mower

         aʊ + ə = auə, as in power, hour.

Ø  /eɪə/ player           /peɪə/

Ø  /aɪə/ fire    /faɪə/

Ø  /ɔɪə/ royal  /rɔɪəl/

Ø  /əuə/ mower         /məuə/

Ø  /auə/ hour /hauə/

 the pronunciation of English triphthongs. Being aware of it will help you not only to sound more natural and fluent but also to understand what native speakers say better.
