Introduction
Phonetics is an essential component of the Algerian Baccalaureate English exam. Every year, students lose marks unnecessarily on phonetics questions simply because they neglect this topic. This comprehensive guide covers all the phonetics rules you need to master for the BAC exam: word stress, sentence stress, intonation patterns, and pronunciation rules for -ed and -s endings, silent letters, and more.
Why Phonetics Matters for the BAC Exam
In the Algerian BAC English exam, phonetics typically appears in Part One (Reading and Comprehension) or as a separate language exercise. You may be asked to:
- Classify words according to their stressed syllables
- Choose the correct pronunciation of -ed or -s endings
- Identify silent letters in words
- Match words with their phonetic transcriptions
- Mark intonation patterns in questions and statements
Learning Objectives
- Master word stress rules for two-syllable and multi-syllable words
- Understand sentence stress and weak forms
- Recognise and apply rising and falling intonation patterns
- Correctly pronounce -ed endings (/t/, /d/, /ɪd/) and -s endings (/s/, /z/, /ɪz/)
- Identify common silent letters in English words
- Apply phonetic rules in BAC-style exercises
Part 1: Word Stress (الضغط النفطي / التشديد على المقاطع)
Word stress refers to the emphasis placed on a particular syllable in a word. Stressed syllables are louder, longer, and higher in pitch. In phonetic transcription, stress is marked with a vertical line (ˈ) before the stressed syllable.
1.1 General Rules for Word Stress
| Rule | Examples | Pattern |
|---|---|---|
| Two-syllable nouns and adjectives — stress on the first syllable | TAble, PRETty, MONey, CLEver, WINdow | ˈ○○ |
| Two-syllable verbs and prepositions — stress on the second syllable | beGIN, inVITE, aRRIVE, deCIDE, beTWEEN | ○ˈ○○ |
| Words ending in -tion, -sion, -ic, -ical, -ity — stress on the syllable before the suffix | eduCAtion, deciSION, eCOnomic, poLITical, aBILity | ○○ˈ○○ |
| Words ending in -cy, -ty, -phy, -gy, -al — stress on the third syllable from the end | deMOcracy, uniVERsity, geOGraphy, biOLogy, criTIcal | ○ˈ○○○ |
| Compound nouns — stress on the first part | GREENhouse, BLACKboard, FOOTball, BEDroom, TOOTHbrush | ˈ○○○ |
| Compound adjectives and verbs — stress on the second part | old-FASHioned, bad-TEMpered, unDERstand, oVERcome | ○ˈ○○ |
1.2 Common Word Stress Patterns for BAC
| Suffix | Stress Rule | Examples |
|---|---|---|
| -tion / -sion | Stress on the syllable BEFORE the suffix | inforMAtion, populaTION, confuSION, teleVIsion |
| -ic / -ical | Stress on the syllable BEFORE -ic/-ical | scienTIFic, hisTORical, demoCRAtic, geoGRAphical |
| -ity / -ety | Stress on the syllable BEFORE -ity/-ety | curiOSity, socIety, anxiEty, responsiBILity |
| -graphy / -logy | Stress on the first syllable of the suffix | geOGraphy, biOLogy, psyCHOLogy, phoTOGraphy |
| -ate (verbs) | Stress on the first syllable (usually) | EDucate, CALculate, COMmunicate, DEMonstrate |
| -ate (nouns/adjectives) | Stress on the first syllable | FORtunate, PASsionate, ACcurate |
Part 2: Sentence Stress and Weak Forms
In connected speech, not all words are stressed equally. Content words (nouns, main verbs, adjectives, adverbs, question words) are usually stressed. Function words (pronouns, prepositions, articles, auxiliary verbs) are usually unstressed and take weak forms.
2.1 Content Words (Stressed) vs Function Words (Unstressed)
| Word Type | Stressed? | Examples |
|---|---|---|
| Nouns | ✅ Stressed | EDucation, GOVernment, ENvironment |
| Main Verbs | ✅ Stressed | I WANT to GO home. |
| Adjectives | ✅ Stressed | A BEAUtiful SUNny day |
| Adverbs | ✅ Stressed | He ran QUICKly. |
| Question Words | ✅ Stressed | WHAT are you doing? WHERE is he? |
| Pronouns | ❌ Unstressed | I saw him at the park. |
| Prepositions | ❌ Usually unstressed | Go to the shop. |
| Articles | ❌ Unstressed | A book, the table |
| Auxiliary Verbs | ❌ Usually unstressed | I can swim. (weak: /kən/) |
2.2 Weak Forms — Essential for BAC Listening
| Word | Strong Form | Weak Form | Example |
|---|---|---|---|
| to | /tuː/ | /tə/ | I want tə go. |
| can | /kæn/ | /kən/ | I kən swim. |
| for | /fɔːr/ | /fər/ | This is fər you. |
| from | /frɒm/ | /frəm/ | I’m frəm Algeria. |
| some | /sʌm/ | /səm/ | Get səm water. |
| and | /ænd/ | /ənd/ or /ən/ | You ən me. |
| that (conjunction) | /ðæt/ | /ðət/ | I know ðət he’s right. |
Part 3: Intonation (التنغيم)
Intonation refers to the rise and fall of the voice when speaking. In English, intonation can change the meaning of a sentence. There are two main patterns:
3.1 Falling Intonation (↘)
Used in:
- Statements: I live in Algiers. ↘
- Commands: Sit down. ↘
- Wh-questions: What is your name? ↘
- Exclamations: What a beautiful day! ↘
- Tag questions expecting agreement: It’s cold, isn’t it? ↘ (you agree with me)
3.2 Rising Intonation (↗)
Used in:
- Yes/No questions: Are you a student? ↗
- Polite requests: Could you help me? ↗
- Lists (before the last item): I bought apples ↗, oranges ↗, and bananas ↘.
- Tag questions showing uncertainty: You’re coming, aren’t you? ↗ (I’m not sure)
- Question tags expressing surprise: You did what? ↗
Part 4: Pronunciation of -ed Endings
The -ed ending of regular verbs in the past simple and past participle can be pronounced in three ways: /t/, /d/, or /ɪd/.
| Pronunciation | Rule | Examples |
|---|---|---|
| /t/ (unvoiced) | After unvoiced sounds (except /t/): /p/, /k/, /f/, /s/, /ʃ/, /tʃ/, /θ/ | worked (work |
| /d/ (voiced) | After voiced sounds (except /d/): vowels and voiced consonants /b/, /g/, /l/, /m/, /n/, /z/, /v/, /ð/ | played (play |
| /ɪd/ | After /d/ and /t/ sounds | wanted (want |
Easy Mnemonic: The -ed ending sounds like /ɪd/ only when the base verb ends in /t/ or /d/. Otherwise, if the final sound is unvoiced, say /t/; if voiced, say /d/.
Part 5: Pronunciation of -s / -es Endings
The plural -s, possessive -‘s, and third person singular -s can be pronounced /s/, /z/, or /ɪz/.
| Pronunciation | Rule | Examples |
|---|---|---|
| /s/ (unvoiced) | After unvoiced sounds: /p/, /t/, /k/, /f/, /θ/ | cats (cat |
| /z/ (voiced) | After voiced sounds: vowels and voiced consonants /b/, /d/, /g/, /l/, /m/, /n/, /ŋ/, /v/, /ð/ | dogs (dog |
| /ɪz/ | After sibilant sounds: /s/, /z/, /ʃ/, /ʒ/, /tʃ/, /dʒ/ | watches (watch |
Part 6: Silent Letters (الحروف الصامتة)
Many English words contain letters that are not pronounced. Here are the most common silent letter patterns for BAC level:
| Silent Letter | Rule / Position | Examples |
|---|---|---|
| b | Silent after m and before t | comb (kʌm), thumb, climb, debt, doubt |
| k | Silent before n at the start of a word | know (noʊ), knee, knife, knock, knowledge |
| w | Silent before r and sometimes before ho/h | write (raɪt), wrong, wrist, answer, sword, who (huː) |
| g | Silent before n (especially at the start or end) | gnat (næt), sign (saɪn), design, foreign, campaign |
| h | Silent at the start of some words, after ex, and in gh | hour (aʊər), honest, exhibit, vehicle, honour, ghost (ɡoʊst) |
| p | Silent before s, n, t at the start | psychology (saɪˈkɒlədʒi), pneumonia, ptarmigan, receipt (rɪˈsiːt) |
| l | Silent in certain common words | half (hɑːf), calf, talk, walk, could, should, would |
| t | Silent in some common words | castle (ˈkɑːsəl), listen, often, Christmas, whistle, fasten |
| gh | Silent in many common words | thought (θɔːt), brought, caught, taught, high, neighbour, light |

BAC Exam Tips: Phonetics Section
- Read the instructions carefully: The BAC exam often uses specific phrasing like “Classify the following words according to the pronunciation of the final -ed” or “Pick out from the text a word with a silent letter.”
- Listen to the stress patterns: When you learn new vocabulary, always learn the stress pattern too. Write the stressed syllable in CAPITALS in your vocabulary notebook.
- Watch out for homographs: Some words change stress depending on their part of speech. E.g., REcord (noun) vs reCORD (verb), PREsent (noun) vs preSENT (verb).
- Practice with past BAC papers: Download and practise phonetics questions from previous BAC exams — they follow consistent patterns.
- Read aloud daily: Reading English texts aloud helps develop muscle memory for correct pronunciation and stress.
• -ed after /t/ or /d/ → /ɪd/ (wanted, needed)
• -ed after other unvoiced → /t/ (worked, laughed)
• -ed after other voiced → /d/ (played, loved)
• -s after /s/, /z/, /ʃ/, /ʒ/, /tʃ/, /dʒ/ → /ɪz/ (watches, boxes)
• -s after unvoiced → /s/ (cats, books)
• -s after voiced → /z/ (dogs, cars)
• Wh-questions → Falling ↘
• Yes/No questions → Rising ↗
• Words ending in -tion, -sion, -ic, -ity: stress on the syllable BEFORE the suffix
Summary
Mastering phonetics is a relatively quick way to earn guaranteed marks in the BAC English exam. The rules are consistent and predictable — unlike some aspects of grammar or writing. Focus on:
- Word stress rules (especially -tion, -ic, -ity patterns)
- -ed and -s ending pronunciations (the most tested phonetics topic)
- Silent letters (frequently tested in BAC reading comprehension)
- Intonation patterns (rising for Yes/No questions, falling for Wh-questions)
- Practising with past BAC papers to familiarise yourself with the question format
Remember: phonetics is not just for the exam — correct pronunciation, stress, and intonation will make your spoken English much more natural and understandable!
