Stress Timed vs. Syllable Timed

Isochrony is the fancy word that describes the rhythmic division of time into equal portions by a language. When referring the rhythm, this is talking about one of the variables of prosody, others being intonation, stress and tempo of speech.

Now, although wikipedia has postulated 3 alternative ways in which a language can divide time, the focus will be on the distinction between syllable-timed and stress-timed languages and the rhythmic differences.

  1. The duration of every syllable is equal (syllable-timed);

  2. The duration of every mora is equal (mora-timed).

  3. The interval between two stressed syllables is equal (stress-timed);

English is a stress-timed language. This means that the interval between two stressed syllables is equal. It also means that the duration of every syllable is not necessarily equal.

If English was a syllable-timed language, then as we add more words to the sentence, it should theoretically get longer and longer. This does not happen. Instead, unstressed syllables/words are said quicker.

In English, the time it takes to say something does not depend on the number of syllables.

If you are transitioning to English from a syllable-timed language, the rhythm of your English speech may sound foreign or overly cautious because you will tend to give equal stress to each syllable.

A quick internet search will help you figure out whether your native language is a syllable-timed or syllable-stressed language but I've included a few examples.


English, Thai, German, Russian, Danish, Swedish, Norwegian, Dutch


French, Italian, Spanish, Icelandic, Cantonese Chinese, Mandarin

If you try to apply the same rhythm to English as you would a syllable-timed language, then it may come across as boring, mundane, unexpressive and robotic.

Typically, stressed syllables and words will include content words. These will include: main verbs, nouns, adjectives, adverbs and negative auxiliaries.

Words that are more typically left unstressed include structure words. These will include: pronouns, prepositions, articles, conjunctions and auxiliary verbs.

In order to work on this, read a newspaper out loud. Think about which words should be stressed and which words shouldn't. Practice saying words quicker or slower depending on whether they are content or structure words.
