Introduction to Phonetics and

Phonology

Plosives

• also called STOP CONSONANTS

• the breath is completely stopped at some point in the mouth and then released with a slight explosion

• speech organs which may form plosives: lips

(bilabial plosives), tip of the tongue (alveolar plosives), back of the tongue (velar plosives)

• all six plosives (/p, b, t, d, k, g/) may occur at the beginning of words, in the middle of words and at the end of words

• these positions are important because plosives are articulated differently in different positions

/p, b/

bilabial plosives

• the lips are closed firmly, the soft palate is raised so that the air cannot go through the nose, but is trapped in the mouth for a while

• when the lips open suddenly, the air rushes out with a slight explosion or a popping noise

• before the lips open, other speech organs assume the position for the following sound, whether it be a vowel or a consonant

• /p/ - strong, voiceless

• /b/ - weak, voiced

• when /p/ is found at the beginning of a word, it has a special feature – ASPIRATION

• e.g.

pull, pot, put, pat, pet, pit

• /p/ between vowels is less aspirated

• e.g.

happy, paper, supper, apply

• in final position, /p/ is also less aspirated

• e.g.

rip, rope, tap, cap, wrap

• /b/ never has aspiration

• e.g.

book, bar, back, bell, bit, bean

• /p/ at the end of words shortens the preceding vowel, whereas /b/ is weak and lengthens the preceding vowel

• consonant clusters of /p/ or /b/ and other plosives are produced a little differently (topic of our next class)

/t, d/

alveolar plosives

• the tip of the tongue is pressed against the alveolar ridge

• the soft palate is raised, the breath does not go into the nasal cavity, it stays trapped in the mouth for a while

• the sides of the tongue are firmly pressed against the sides of the palate so the air cannot pass over the sides of the tongue

• the tip of the tongue is lowered suddenly and the air rushes out with a slight explosion or a popping noise

• /t/ is strong, voiceless and aspirated

• e.g.

top, tin, tan, ten, ton

• /d/ is short, weak and never aspirated

• when /t/ occurs word-medially, it loses some aspiration

• in final position, /t/ is also less aspirated and shortens the vowel before it

• /d/ is weak, makes very little noise but lengthens the vowel that precedes it

• when followed by other plosives or /m, n, l/, /t/ and /d/ are pronounced differently (topic of our next class)

/k, g/

velar plosives

• the back of the tongue is in contact with the soft palate, which is raised, so the air cannot go into the nasal cavity and is trapped in the mouth

• when the tongue is lowered suddenly from the soft palate, the breath rushes out of the mouth with a slight explosion or a popping sound

• /k/ is strong, voiceless and aspirated

• e.g.

cot, cat, cart, kill, keep

• when /k/ occurs between vowels, the aspiration is weaker or even absent

• /g/ is weak, voiced and has no aspiration

• in final position, /k/ shortens the vowel before it,

/g/ lengthens the vowel before it

• when /k/ and /g/ are followed by other plosives or /m/ or /n/, these sounds are produced in a different manner (topic of our next class)

Affricates

• /t  , d  /

• these two phonemes are articulated both with friction and with explosion of air

• tip of the tongue touches the back part of the alveolar ridge

• the soft palate is raised so that air is trapped in the mouth for a short time

• tip of the tongue moves away from the alveolar ridge a little and then the tongue comes to the position for /  / or /  /, when friction is heard

• friction is not that long with these two phonemes

palato-alveolar affricates

• /t  , d  / are not as strong as Serbian /č/ and

/dž/, they are much softer

• /t  / is strong and voiceless

• /d  / is weak and voiced

• in final position, /t  / shortens the preceding vowel, whereas /d  / lengthens the preceding vowel

Glides

• all three consonants produced with a quick, smooth, non-friction glide towards the vowel that follows

• /j, w, r/

/j/

• this consonant is a quick glide from the position of /i:/ or /  / or any other vowel

• sometimes called a semi-vowel

• phonetically like a vowel (articulated in such a way), but phonologically like a consonant (it only occurs before vowel phonemes)

• voiced palatal sound

palatal glide

/w/

• this consonant is a quick glide from the position of /u:/ or /  / or any other vowel that follows

• more difficult to pronounce than /j/, because many languages, including Serbian, do not have it

• a difference must be made between /v/ and /w/

• lips are noticeably rounded!

bilabial glide

• /w/ does not occur in word-final positions

• wh-words in some dialects of English pronounced with /  / (

where, which, why

)

/r/

• the tongue is curved, the tip is pointing towards the hard palate

• the tip of the tongue is not close enough to the palate to produce friction

• the lips are quite rounded, especially when /r/ is word-initial

• the soft palate is raised, voiced air flows quietly between the tip of the tongue and palate without friction

palato-alveolar glide

• in RP /r/ is only pronounced before vowels, never before consonants

• when a word ending in –r in spelling is followed by another word which begins in a vowel, then

/r/ is pronounced

• e.g.

never again

/nev  r  ’gen/

• LINKING R

• sometimes /r/ is heard when there is no equivalent in spelling

• e.g.

Africa and Asia

/    /

• INTRUSIVE R

• some speakers can be heard saying such phrases, but it is not a preferred way of usage
