IELTS pronunciation · Consonant sounds

Silent letters (knee, listen, foreign)

Silent letters are letters in English spelling that are not pronounced when speaking a word aloud, such as the 'k' in 'knee' or the 't' in 'listen'. Mastering them ensures your speech sounds natural and prevents phonetic reading habits from lowering your IELTS Pronunciation score.

Technique

How to say it

  1. 1

    Identify historical spelling patterns where initial consonants like 'k' in 'knee' /niː/ and 'w' in 'write' /raɪt/ are completely dropped.

  2. 2

    Omit medial consonants in fixed clusters, such as the silent 't' in 'listen' /ˈlɪsn/ and 'castle' /ˈkɑːsl/.

  3. 3

    Drop trailing consonants in specific endings like the silent 'b' in 'climb' /klaɪm/ and 'thumb' /θʌm/.

  4. 4

    Keep silent 'g' unvoiced in words like 'foreign' /ˈfɒrən/ and 'sign' /saɪn/ without adding a hard /ɡ/ sound.

Watch out

Common mistakes

  • →Over-pronouncing silent letters by reading words phonetically, such as articulating the 'b' in 'subtle' or 'debt'.
  • →Inserting a hard /ɡ/ sound into words with silent 'g' like 'foreign' or 'campaign'.
  • →Pronouncing the initial 'k' or 'w' in common words like 'knife', 'knee', 'wrap', and 'wrist'.

In the exam: Avoid spelling-based pronunciation when using high-level vocabulary, as mispronouncing silent letters in words like 'subtle' or 'fascinating' instantly signals a lack of phonological control to the examiner.

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.
