Oral English: Consonant Sounds and Sound Clusters
The 24 consonant phonemes organised by voiced/voiceless pairs and manner of articulation, Ghanaian substitution errors (θ/f, l/r, final cluster cutting), homophones, and the pronunciation of -s and -ed endings.
A security phrase at Kotoka check-in — "six thick textbooks" — detonates every Ghanaian weak spot at once: /s/ vs /θ/, cluster /ks/, /kt/, final clusters -ft, -ks, -cts. Announcers train on exactly such tongue-twisters to stay intelligible to international pilots.
Key Syllabus Learning Objectives
- 1Group the 24 consonants into plosives, fricatives, affricates, nasals, lateral and approximants
- 2Produce and hear every voiced/voiceless pair on command
- 3Identify the phonetic reason for common Ghanaian substitutions (θ→f/s, final-cluster cutting)
- 4Apply the three pronunciation rules for plural/noun -s and regular -ed endings
- 5Pick out homophones and the odd-sound consonant in WAEC oral objective items
The Consonant Grid: Manner, Place, Voicing
- Voicing pairs to drill as minimal pairs: sip/zip, fan/van, cap/gab, and think/this, which shows θ and ð as a voiceless/voiced pair.
- ŋ (sing) never begins an English word — that is why "ng" at the start of Ghanaian names surprises foreign ears.
- /h/ is the ONLY glottal fricative; dropping it ("eart" for "heart") is a perceptible oral error.
- The approximants w (round lips) and j (the "yes" sound) are consonants — "y" and "w" as vowel letters mislead spellers.
A drama class drill at a Kumasi SHS: "The three brothers threw thirty threads" — tongue-twister attacking θ/ð clusters, exactly the sounds Ewe/Twi-influenced mouths flatten.
Name any consonant by its three coordinates: manner + place + voiced/voiceless.
Ghanaian Substitution Errors and Their Fixes
- Minimal-pair drills: thin/sin, thought/sought, borrow/narrow, light/right, floor/flew.
- Word-final /v/ → /f/ is common and WAEC-TOLERATED but still marked in careful speech: "of" pronounced /ɒv/, never /ɒf/, before vowels.
- Aspirate /h/ at word starts: house, heart, behind — a silent-h language learner should exaggerate the puff of air.
- No final devoicing: "bed" must not sound like "bet"; "cabs" keeps /z/.
A prefect reading the assembly notice: "The NEAREST SHOPS close at FIVE" — the r/l flip turns nearest into "nearest" but shops into "shobs"; oral examiners log exactly these swaps.
Every accent error is a missing sound the mother tongue does not keep — train the sound, then the word.
Homophones: One Sound, Two Spellings
- Pronounce-both-aloud discipline: if your two pronunciations match, they are homophones; if not, you have found a local variant (aunt /ɑ:nt/ vs /ænt/ — both standard, not homophones).
- 'flour/flower', 'soul/sole' and 'piece/peace' belong in a personal list of ten pairs built each term.
- Some pairs vary by accent: "horse/hoarse" differ in careful BrE but merge in fast speech; WAEC follows the careful distinction.
- In essays the cost is a wrong word, not a wrong sound: "their/there" slips strike Mechanical Accuracy.
A market sign "FRESH FISH FOR SALE / SEE PRICE INSIDE" — a child reading it aloud produces the sea/see homophone live.
Oral exam: ears decide; written exam: meaning decides which spelling earns the mark.
The -s and -ed Ending Rules
- Method: say the base word's LAST sound, then add the matching tail — never look at the spelling.
- Adverbs from -ed adjectives are NOT past tenses: "a gifted boy" — the /ɪd/ or /t/ still follows the same sound logic.
- "He asked" = /ɑ:skt/ in fast speech is one syllable — cluster, not extra vowel.
- Third-person singular of verbs obeys the noun-plural rules: reaches /ɪz/, sleeps /s/, learns /z/.
A dictation drill: "The bosses passed the messages and wished the matches back" — every -s/-ed lands in the /ɪz//t/ clubs, one after another.
Voice decides the ending: voiceless base → /s//t/; voiced base → /z//d/; sibilant/t/d base → /ɪz//ɪd/.
- Oral Paper 3 Section A "same sound" items: compare the underlined CONSONANT only; words like "chemical" /k/ vs "cheese" /tʃ/ teach that "ch" splits into two sounds by word origin.
- For the passage-reading section, slow down on cluster endings (-sts, -nths, -lvd): final-cluster clarity is worth more points than speed.
- Memorise the "th" pairs WAEC recycles: think/thing/three/mother/breathe/both — voiceless in the first three, voiced in mother/breathe, both forms acceptable for "both" in connected speech.
- Odd-consonant-out questions: transform each option to phonemes mentally, circle the consonant, and compare ONE feature — place or voicing, not both.
- In the "number of syllables" items, the -ed /ɪd/ and -s /ɪz/ endings ADD a syllable ("needed" 2, "buses" 2) while /t/ and /z/ do not ("walked" 1, "dogs" 1).
- Substituting /s/ or /f/ for /θ/: "I go to church on Sunday" arriving as "I go to cars on Sundi" — practice the tongue-between-teeth position.
- Deleting the last consonant of clusters: "and" → "an", "texts" → "tek", "best" → "bes".
- Pronouncing every -ed as a separate syllable: "walked" as "walk-ed" (two syllables) instead of /wɔ:kt/.
- Voicing voiceless pairs and vice versa: "zebra" as "sebra", "very" as "fery", "peace" as "beast-p", so peace/beast-p confuses the pair.
- Confusing nasal ŋ with n before k: "sink" /sɪŋk/ needs the back nasal — tongue at the soft palate.
- Saying /wɪtʃ/ as "wich" for which/witch — the distinction is tested in minimal-pair items.
- Can I recite the 24 consonants grouped by manner of articulation?
- Can I produce all nine voiced/voiceless pairs and feel the throat buzz?
- Can I correct "dis ting" to "this thing" and explain the tongue position?
- Can I pronounce cups/dogs/buses and walked/played/wanted with the right tails?
- Can I list ten homophone pairs and use each spelling correctly in a sentence?
