English Consonants

 Consonants are a crucial component of speech sounds in the English language. They are produced when the airflow is either completely blocked or partially restricted as it moves through the mouth or throat. Unlike vowels, which are voiced without obstruction, consonants involve some form of contact between different parts of the vocal tract. These speech sounds can occur at the beginning, middle, or end of words and help form the structure and rhythm of language. Consonant articulations are relatively easy to feel and, as a result, are most conveniently described in terms of places and manners of articulation. It is often necessary to specify the duration of the sound, the airstream mechanism involved, and the direction of air flow.

From the phonological point of view, consonants are those units that function at the margins of syllables, either singly or in clusters. Briefly, consonants can be defined as the speech sounds articulated with interruption in the lung air and/or some obstacles in the vocal tract.

Places of Articulation of Consonants

Consonants are speech sounds in which the air from the lungs is seriously obstructed by the different articulators at different places in the vocal tract, and then goes out through the oral passage and, in some cases, through the nostrils. According to their places of articulation, English consonant phonemes can be divided into nine types as discussed below.

Bilabial Consonant: To produce the bilabial consonants, the two lips function as the primary articulators. They first make contact to block the lung air and then go apart to release it. English bilabial consonants include / p/, / b/, /m / found in words like ‘pen’, ‘bat’, and ‘man’.

Labio-dental consonant: To articulate the labio-dental consonants, the lower lip makes contact with the upper front teeth. English labio-dental consonants are /f/ and / v /, found in words like ‘fan’ and ‘van’.

Inter-dental consonant: To pronounce the inter-dental consonants, the tongue tip is slightly pushed between the lower and upper front teeth. English interdental consonants are /δ/ and /θ/  in words like ‘this’ and ‘think’.

Alveolar Consonant: The alveolar sounds involve the tongue touching the ridge  just behind the upper front teeth.  English alveolar consonants include /t/, /d/, /s/, /z/, /n/, and /l/ found in words like ‘top’, ‘dog’, ‘sun’, ‘zoo’, ‘net’ and ‘lip’.

Post-Alveolar Consonant: To produce the post-alveolar consonant, the tip of the tongue articulates with the back part of the upper alveolar ridge. The English language has only one post- alveolar sounds are/ʃ/, /ʒ/, /tʃ/, and /dʒ/, found in words like "she", "vision", "chair", and "jam".

Palato-Alveolar Consonant: To produce the palate-alveolar consonants, the blade, or tip and blade, of the tongue articulates with the alveolar ridge, and there is at the same time a rising of the front of the tongue towards the hard palate. The English language possesses four palato-alveolar consonants are /ʃ/ as in "shy", /ʒ/ as in "vision”, /tʃ/ as in "chip", and /dʒ/ as in "jam".

Palatal Consonant: The front of the tongue articulates with the hard palate to produce the palatal consonant. The English language has only one palatal consonant / j /. The palatal sound /j/, as in "yes", is made by raising the tongue to the hard palate.

Velar Consonant: Velar consonants, such as /k/, /g/, and /ŋ/ (as in "king"), are produced by the back of the tongue touching the soft part of the roof of the mouth known as the velum.

Glottal consonant: Glottal sounds like /h/ (in "hat") are formed in the glottis, which is the space between the vocal cords. In some dialects, a glottal stop [ʔ] may also be used, as in the middle of the expression "uh-oh".

In conclusion, understanding English consonants and their places of articulation is fundamental for accurate pronunciation and phonetic study. Each consonant sound is shaped by where and how it is articulated, contributing to the rich diversity of English speech.
