Phonetics and Phonology
What this domain tests
Phonetics describes speech sounds; phonology describes how they pattern in a language. The exam tests phonetic transcription, phoneme contrasts, syllable and stress structure, connected-speech processes and intonation, and the classroom use of this knowledge for pronunciation teaching.
Core rules and concepts
- Consonants are classified by voicing, place and manner: /p b/ are bilabial plosives, /f v/ labiodental fricatives, /tʃ dʒ/ palato-alveolar affricates, /ŋ/ a velar nasal.
- RP has twelve monophthongs and eight diphthongs; General American differs in vowel quality and is rhotic, pronouncing /r/ after vowels.
- Phoneme versus allophone: aspirated [pʰ] in pin and unaspirated [p] in spin are allophones of /p/, so swapping them does not change meaning; swapping /p/ for /b/ does.
- Minimal pairs establish phonemic status: ship/sheep (/ɪ/–/iː/), thin/sin (/θ/–/s/).
- Syllable structure is onset–nucleus–coda. English allows clusters such as /spr/ in spring and up to four coda consonants in texts /teksts/.
- Lexical stress can be contrastive: REcord (noun) versus reCORD (verb). Sentence stress highlights information, usually with the nuclear accent on the last content word of the tone unit.
- Weak forms reduce function words (and /ən/, can /kən/), producing English's stress-timed rhythm.
- Connected speech: assimilation (ten bikes → /tem baɪks/), elision (next day → /neks deɪ/), linking /r/, catenation.
- Intonation: falling tone signals completion and statements; rising signals yes/no questions and continuation.
Worked example
Why is comfortable usually /ˈkʌmftəbl/ rather than four clean syllables? Identify the primary stress first, then apply reduction: the post-stress schwa is syncopated and adjacent consonants compress, giving three syllables. The reasoning route - stress first, then elision and weak syllables - is what the exam rewards when it asks you to predict learner difficulties.
Traps
- Confusing letters with sounds: the plural -s is /s/ in cats, /z/ in dogs, /ɪz/ in buses.
- Counting syllables from spelling rather than from the phonological form.
- Forgetting that GA is rhotic when comparing varieties.
- Assuming one intonation contour fits every question type.
