IELTS pronunciation · Consonant sounds

z versus s (rise / rice)

The sounds /z/ and /s/ share the same tongue and lip position but differ in voicing, with vocal cord vibration occurring only for /z/. Distinguishing clearly between these two consonants prevents vocabulary confusion and ensures plural and third-person verb endings sound natural and precise.

Technique

How to say it

  1. 1

    Place the tip of your tongue close behind your upper front teeth near the alveolar ridge without touching it.

  2. 2

    Breathe out air through the narrow channel to produce an unvoiced hiss for /s/, as in 'rice'.

  3. 3

    Keep your tongue in the exact same position and turn on your vocal cords to create a voiced buzz for /z/, as in 'rise'.

  4. 4

    Check word endings, voicing final 's' as /z/ whenever it follows a vowel or voiced consonant.

Watch out

Common mistakes

  • →De-voicing word-final /z/ into /s/ on plural nouns and verbs, causing words like 'eyes' or 'plays' to sound like 'ice' or 'place'.
  • →Pronouncing the written letter 's' as /s/ in common words where standard pronunciation requires /z/, such as 'music', 'reason', or 'because'.
  • →Failing to differentiate voiced verbs from unvoiced nouns in related pairs like 'to advise' (/z/) versus 'advice' (/s/).

In the exam: Consistently voicing /z/ on plural nouns and third-person singular verbs demonstrates strong phonological control and prevents basic grammatical endings from being obscured.

Frequently asked questions

How much does pronunciation count in IELTS Speaking?+

A quarter of your Speaking band. Examiners judge how easy you are to understand and how well you use features like stress, rhythm and intonation, not whether you sound British or American.

Do I need a native accent for Band 8?+

No. An accent is fine at every band. What matters is that individual sounds are clear, stress falls on the right syllables and your intonation helps the listener follow you.

How should I practise these lines?+

Read each line slowly, then at natural speed, then record yourself and compare. Say the sentences in a real answer next, because examiners hear your pronunciation while you think, not while you read.
