Pronunciation: Stress, Intonation, and Connected Speech

Pronunciation is the fourth equally weighted criterion in IELTS Speaking. Many candidates neglect pronunciation in their preparation, focusing only on vocabulary and grammar. This is a mistake — pronunciation can make a full band of difference. This lesson covers the specific features that examiners assess and how to improve them.

What the Examiner Assesses

What strong pronunciation sounds like in the speaking test

• A range of pronunciation features is in play across the answer — word stress, sentence stress, intonation, rhythm, connected speech — not just clear individual sounds.
• The candidate is generally easy to understand throughout, including on less familiar topics.
• Where an L1 accent is present, it does not impede the examiner's understanding of what is being said.
• Stress patterns and intonation are used purposefully to mark new information, contrast, and emphasis.

Common reasons pronunciation caps a candidate at Band 6

• Mispronunciation of individual words occasionally requires the listener to work to follow.
• Word stress patterns are inconsistent — sometimes correct, sometimes shifted onto the wrong syllable.
• Intonation flattens across long answers, so emphasis and contrast are not signalled clearly.
• Connected speech features (linking, weak forms) are absent, so speech sounds clipped and effortful.

Critical insight: The examiner is not assessing whether you sound like a native speaker. They are assessing whether your pronunciation features (stress, intonation, rhythm, individual sounds) support clear communication. Refer to the official Cambridge IELTS Speaking Pronunciation public band descriptors for the authoritative criteria.

Feature 1: Word Stress

Every English word with more than one syllable has a stressed syllable — one syllable that is louder, longer, and higher in pitch.

Why It Matters

Incorrect word stress can make words unrecognisable:

Correct Stress	Incorrect Stress	Risk
EDucation	eduCAtion	May confuse the listener
deVELopment	DEVelopment	Sounds unnatural
GOVernment	governMENT	Hard to understand
techNOLogy	TECHnology	Disrupts communication

Common Stress Patterns

Stress Patterns for Common Suffixes
═══════════════════════════════════════════════════════
-tion / -sion    Stress on syllable BEFORE suffix
                 edu-CA-tion, dis-CUS-sion, in-for-MA-tion

-ic / -ical      Stress on syllable BEFORE suffix
                 e-co-NOM-ic, tech-NO-lo-gi-cal

-ity             Stress on syllable BEFORE suffix
                 u-ni-VER-si-ty, com-mu-NI-ty

-ment            Stress usually stays on root word
                 de-VEL-op-ment, EN-vi-ron-ment

-able / -ible    Stress usually stays on root word
                 com-FOR-ta-ble, ac-CES-si-ble

Stress Shifts Between Word Forms

Noun	Verb
REcord	reCORD
PREsent	preSENT
OBject	obJECT
CONtrast	conTRAST
INcrease	inCREASE

Band 7+ tip: When learning new vocabulary, always learn the stress pattern along with the meaning. Mark the stressed syllable and practise saying the word aloud.

Feature 2: Sentence Stress

In English sentences, certain words are stressed (content words) and others are unstressed (function words).

Content Words (Stressed)

• Nouns: education, government, technology
• Main verbs: believe, argue, suggest
• Adjectives: significant, important, effective
• Adverbs: strongly, significantly, particularly
• Negatives: not, never, hardly

Function Words (Unstressed)

• Articles: a, an, the
• Prepositions: in, on, at, for, to
• Pronouns: he, she, it, they
• Auxiliary verbs: is, are, was, have, do
• Conjunctions: and, but, or

Example

"I THINK the GOVernment should INvest MORE in EDucation."

The stressed words carry the meaning. The unstressed words connect them but are spoken quickly and quietly.

Why This Matters

If you stress every word equally (a common feature of some first languages), your speech sounds robotic and is harder to follow. Natural English has a rhythm created by the alternation of stressed and unstressed syllables.

Feature 3: Intonation

Intonation is the rise and fall of your voice pitch across a sentence. It communicates meaning beyond the words themselves.

Falling Intonation (Finality, Certainty)

Used for:

• Statements: "I believe education is essential." (pitch falls at the end)
• Wh-questions: "What do you think about this?" (pitch falls at the end)
• Commands: "Consider the evidence carefully." (pitch falls)

Rising Intonation (Uncertainty, Questions)

Used for:

• Yes/no questions: "Do you agree?" (pitch rises)
• Lists (non-final items): "We need to invest in healthcare, education, and infrastructure." (rising on "healthcare" and "education," falling on "infrastructure")
• Expressing uncertainty: "I suppose so?" (rising = uncertain)
