Consonant Sounds
There are forty-four sounds in
English and they are divided into two groups: Consonant sounds and vowel
sounds.
Consonant sounds are
sounds whose articulation involves the contact of the organs of speech. This
means that when we produce consonant sounds, our speech organs (our lips,
teeth, tongue, alveolar ridge, hard palate, soft palate) make contact with each
other.
There are twenty-four consonant
sounds in English, and they are divided into different groups using three
criteria:
1. Place of articulation,
2. Manner of articulation
3. Voicing
By “place of
articulation”, we mean the speech organs that are involved in the
production of the consonant in question. Some sounds are produced with the two
lips, some with the tongue and teeth, the tongue and alveolar ridge etc. Using
this criteria, we have seven types of consonant sounds:
1. Bilabial sounds:
Produced with the two lips: (p, b, m)
2. Labia-dental sounds:
Produced with the lower lips and upper front teeth (f, v),
3. Dental sounds:
Produced with the contact of the tips of the tongue and the upper front teeth:
4. Alveolar sounds:
Produced with the contact of the tip of the tongue and the alveolar ridge
5. Palatal sounds:
Produced with the contact of the blade of the tongue and the hard palate
6. Velar sounds:
Produced with the contact of the back of the tongue and the soft palate
7. Glottal sounds:
Produced in the larynx- h
By “manner of
articulation”, we mean the manner in which the pulmonic air (the air
we use to form speech sounds) escapes from the mouth. With some sounds, the air
is completely blocked, with some, it escapes with difficulty through the
mouth, and with some others it escapes through the nostrils. Using these
criteria, we have six types of consonant sounds:
1. Plosives or stops: Sounds
in which the air is completely blocked: (p, b, t, d)
2. Fricatives: Sounds
in which the air escapes with difficulty (f, v, s, z etc)
3. Affricates: Sounds
that combined the feature of plosives and fricatives)
4. Nasals: Sounds in
which the air escape through the nostrils (m, n,)
5. Liquids: Sounds
in which the air is blocked, but not as much as in stops and fricatives. The
air escapes through the sides of the mouth (r, l)
6. Glides: Consonants
that have no obstruction of pulmonic air, the speech organs do not make any
form of contact. That is, they are like vowels (w, j)
By “voicing”, we
mean whether or not there is vibration in the vocal cords when the sound is
produced. Using this criterion, we have two types of sound 1. voiceless sounds
(those produced without vibration) and 2. voiced sounds (those produced with
vibration).
The chart below
illustrates the above explanation:
With the above chart, you will
be able to describe each of the sounds. For instance:
1. /p/ is voiceless
bilabial plosive
2. /b/ is voiced
bilabial plosive
3. /f/ is voiceless
labia-dental fricative,
4. /z/ is voiced
alveolar fricative Etc.
