Week 3 – Part 1
PhonologyThe following PowerPoint is to be used as a guideline for the important vocabulary and terminology to know as you do your readings, answering questions, and forming your thoughts and comments for your discussion with fellow classmates.
Phonology—the sound system of a language.
Phonetics—the study of speech and sound.
Phones—the phonetic sounds that occur in a language. Phonemes—the abstract basic units that differentiate words. Allophones—predictable phonetic variants of one phoneme.
Phonology
Acoustic phonetics focuses on the physical properties of sounds
Auditory phonetics is concerned with how listeners perceive these sounds
Articulatory phonetics is the study of how the vocal tract produces the sound of language
Identity of Speech Sounds
Orthography, or alphabetic spelling, does not represent the sounds of a language in a consistent way.
International Phonetic Alphabet (IPA) the phonetic alphabet designed by the International Phonetic Association to be used to represent the sounds found in all human languages
The Phonetic Alphabet
The sounds of all languages fall into 2 classes: consonants and vowels.
Places of Articulation
Manner of Articulation
Articulatory Phonetics
Place of articulationThe horizontal relationship between the articulators. See pg. 236-237 for explanation.
Vocal Tract
See pg. 236-237
Vocal Tract
Stops
Stops are characterized by
involving complete closure in the oral tract, preventing the airflow from exiting through
the mouth
Stops in EnglishPlace of
ArticulationVoice Symbol Example
Bilabial – [p] ‘pig’
+ [b] ‘bear’
Alveolar
– [t] ‘tiger’
+ [d] ‘dog’
Velar – [k] ‘cat’
+ [g] ‘gorilla’
Fricatives and AffricatesFricatives are classified by those sounds that produce a slight hissing noise when they are articulated (e.g. /s/ /f/ /v/). They also continuant consonants, which means they can be produced as long as you have airflow. Affricates, on the other hand, start as plosives and end as fricatives (e.g. only /tʃ/ /dʒ/). Plosive-fricative combinations must be homogranic (i.e. made with the same articulator) to be considered an affricate. What is more, there is a controversy as to whether affricates should be identified as one phoneme; this will be discussed in a later lesson.
Fricatives & AffricatesAffricates Fricativesproduced like plosives, in that they involve a closing stage, a closure stage and a release stage
produced when the active articulator is close to, but not actually in contact with, the passive articulator.
Phonetically, then, affricates are similar to a stop followed by a fricative, they do not, however, behave like a sequence of two segments
voiced or voiceless
Voiceless palato-alveolar [tʄ], as in ‘chimpanzee’, and its voiced counterpart [dʒ] as in ‘jaguar’
Labio-dental, dental, alveolar, palato-alveolar, glottal
Voiceless fricatives
Voiceless fricatives (produced with greater force, generating a louder friction noise, and shorten vowel sounds that precede them.)
/f/ = labiodental /θ/ = dental/s/ = alveolar/ʃ/ = post-alveolar
Voiced fricatives
Voiced fricatives (but produced with little or voicing in initial and final positions)/v/ = labiodental/ð/ = dental/z/ = alveolar /ʒ/ = post-alveolar (*never occurs in initial position)
Fricatives not voiced or voiceless
/h/ = glottal
AffricatesAffricates (voiced/voiceless pairs that have post-alveolar articulation)
/tʃ/ = slightly aspirated and shortens vowels when in final position /dʒ/ = produced with rounded lips
Glottal stop [ʔ]
glottal stop is voiceless since the vocal cords cannot vibrate when
they are in contact
Glottal egressive
• if the glottis is closed then raised, the air above it (in the vocal tract) will be pushed upwards, becoming compressed behind the blockage in the oral tract; this air exits on release of the closure in the oral tract
• ejectives – the stops produced through this mechanism
• ejectives are indicated by an apostrophe [p’]
Vowels
the articulators are far enough apart to allow the airflow to exit unhindered, that is, with open approximation
1. Vowel height: high, mid, low2. Vowels are classified horizontally: front, central, back3. Attitude of lips – rounded and unrounded when making
vowel sounds
Short and Long VowelsEnglish monophthongs include:
Short Long/ɪ/ = win /i:/ = sea/ʊ/ = put /u:/ = do/e/ = ten /ɜ:/ = word/ə/ = about /ɔ:/ = call/æ/ = cat /a:/ = card/ʌ/ = up/ɒ/ = bought
The classifications of 'short' and 'long' are relatively arbitrary and the length of the vowel can be slightly altered, depending on the context (e.g. whether a stressed or unstressed sound follows them).
Short Vowels/ɪ/ tongue position is close and front; the lips are slightly spread/ʊ/ tongue position is a bit close and near the back; the lips are rounded/e/ tongue position is between close-mid and open-mid, and it is front;
the lips are slightly spread /æ/ tongue position is open and front; the lips are slightly spread/ʌ/ tongue position is more open than open-mid and central; the lips are
neutral /ɒ/ tongue position is between open-mid and open and it is back; the
lips are slightly rounded/ə/* tongue position is between close-mid and open-mid and it is central;
the lips are neutral * /ə/ will be discussed in much greater detail later in this course, as it
signifies weakness
Long VowelsIn addition to length, they differ from short vowels in tongue placement and lip positioning. /i:/ tongue position is more close and front than /ɪ/; the lips are only
slightly spread/u:/ tongue position is more less close and back; the lips are only
slightly rounded/ɜ:/ tongue position is open-mid and central; the lips are only slightly
spread/ɔ:/ tongue position is between open-mid and close-mind, and back;
the lips are strongly rounded/a:/ tongue position is more open and mostly back; the lips are neutral
• Nasal vowels – vowels produced with a lower velum
• Oral vowels – vowels produced with a raised velum
• Nasalized vowels – a vowel preceding a nasal stop will be produced with the velum lowered in anticipation of the following consonant, as in ‘bean’. That is the vowel assimilates to the nasality of the following stop
Nasal Vowels vs Oral Vowels
Vowels
Problems with Vowels cont.Another potential problem is the difficulty of hearing the difference between /ə/ and an unstressed /ʌ/. To solve this problem, phonologists have proposed that the schwa (/ə/) phoneme replace the /ʌ/ phoneme, and that /ʌ/ be made into an allophone for the other. The only problem with this proposal is that the schwa phoneme often replaces many other vowel phonemes to signify a weak sound (e.g. the 'a' in about and the second 'o' in photograph are pronounced as a /ə/). Consequently, other phonologists assert that /ə/ should be adopted as an allophone of these unstressed sounds rather than its own phoneme.
Liquids and Glides
Liquids [l] [r] – some obstruction of the airstream in the mouth, but not enough to cause ay real constriction or friction.
Glides [j] [w] – the initial sounds of you [ju] and we [wi] are produced with little obstruction of the airstream.
Diphthongs
Diphthongs are special types of vowels in which the sound is produced by producing one vowel sound and ending in another vowel sound. Thus, diphthongs are typically vowels that are composed of two different vowel sounds.
Diphthongs Diphthongs consist of one vowel sound that glides into another vowel sound. This collision creates a unique speech sound. Often learners mistakingly pronounce them without this glide, and therefore, they need to be guided away from this error. One way to impress this upon them is to inform that the first segment is always stronger than the second. This, hopefully, will raise their awareness and encourage a less 'foreign-sounding' pronunciation.
Diphthongs symbol pronunciation/ɪə/ = ear starts in the close and front and then glides down to a central and open position/eə/ = air starts between close-mid and open-mid and the glides across to the central
and open position/ʊə/* = sure starts a bit close and near the back and then glides down to the central and
open position /eɪ/ = day | starts between close-mid and open-mid, and in front position and glides up
to a close position/aɪ/ = time starts between front and back, and in open position and glides up to a close
position/ɔɪ/ = toy starts between a open-mid and close-mid, and in back position and glides
up to a close position /əʊ/ = go starts in the open and central position and glides up to the back position/aʊ/ = how starts in the open and mostly back position and glides up to the back
position
* usually replaced with /ɔ:/, but can still be helpful in highlighting the differences sometimes heard between 'more' and 'moor'
