Intro to Understanding Syllable Stress in American English

Syllable Timed vs Stress Timed Languages

Hindi is a syllable timed language, as are most languages spoken in the Indian subcontinent. This means that syllables take up the same amount of time to say. As a result, Indian English tends to be more syllable timed.

American English, and most English dialects, are not syllable timed. American English is stress timed. In stress timed languages, a certain rhythm is maintained and not all syllables are the same length. Within words, some syllables are more prominent, or more stressed than others, and other syllables are unstressed.

What happens when you use syllable stress incorrectly?

Studies have found that people remember words by their stress patterns. When we speakers and our brains are trying to interpret what they are saying, our brain uses the stress patterns in order identify the words that are being said. That means that if you are using stress patterns to say words that a speaker isn't familiar with, it's going to make it much harder for you to be understood. It's possible they will not understand you at all, think you meant something else, or take a very long time to figure what you were trying to say. That means that getting stress patterns down correctly is very important in helping people to understand you.

Communication problems can happen when saying words like

, which have similar sounds, but different stress patterns. This is why it’s important to understand and use stress patterns well. If you mistakenly pronounce
with stress on the first syllable, it will sound more like
, and if you pronounce
with stress on the second syllable instead of the first, it will sound more like
. In a sentence like "what did you think of the comedy?" or "what did you think of the committee?", if you are stressing a syllable that people aren't expecting to be the one receiving emphasis, you might cause some confusion.

Many speakers who didn't grow up speaking a stress-timed language or dialect don't realize how important it is, because often times speakers of syllable timed languages or dialects just place less importance on how words are stressed. Research has shown that in Hindi, word stress is less important, and that speakers of Indian English generally don't apply stress rules as rigidly as American English speakers. If someone emphasizes one syllable over an other it's not seen as big of a deal as it would be to an American English speaker's ears.

How are words stressed in American English?

As mentioned above, syllables in stress-timed languages like American English can be stressed syllables or unstressed syllables. There are four areas which we modify when stressing, or unstressing, a syllable. These characteristics are length, volume, pitch, and vowel quality. Stressed syllables are longer, louder, have a higher pitch, and contain clear, distinct vowels. Unstressed syllables are shorter, quieter, have a lower pitch, and have vowels that are not as clear.

Vowel Quality Vowel that occurs in strong syllables , , , or


Stressed syllables have a long length. Stretch out the vowel when you say them.

Unstressed syllables have a short length. Reduce how long the vowel is when you say them.

The first syllable of pencil is long. The second syllable of pencil is short.

The first syllable, mu, is short. The second syllable, si, is long.

The third syllable, cian, is short.

Native speakers of Hindi and other languages from the Indian subcontinent tend to make all the syllables more similar to one another than American English speakers do. Indian English speakers do give some stress to words and make them a little bit longer, but in comparison American English speakers make their stressed syllables much much longer than the average Indian English speaker does, and makes their unstressed syllables deliberately shorter. In order to be better understood by Americans, make sure you pay attention to making your stressed syllables longer, and your unstressed syllables noticeably shorter.


Stressed syllables have a loud volume.

Unstressed syllables have a softer volume.

The first syllable, pen, is louder. The second syllable, cil, is quieter.

quieter louder quieter


Stressed syllables have a higher pitch.

Unstressed syllables have a lower pitch.

The first syllable, pen, has a higher pitch. The second syllable, cil, has a lower pitch.

The first syllable, mu, has a lower pitch. The second syllable, si, has a higher pitch. The third syllable, cian, has a lower pitch.

How native speakers of Hindi use pitch differently than Americans

Native speakers of Hindi and other languages from the Indian subcontinent tend to use pitch very differently. and this difference contributes to why speakers from Indian are deemed by some as having "sing-songy" accents. Hindi speakers do use pitch for emphasis, but unlike Americans a falling pitch might occur on an stressed syllable instead of a rising one, which adds to the confusion.

Vowel Quality

Stressed syllables can contain any vowel except .

Only strong syllables can be stressed.

Unstressed syllables can only contain , , , and .

The first syllable, pen, is louder. The second syllable, cil, is quieter.

The first syllable, mu, is quieter. The second syllable, si, is louder. The third syllable, cian, is quieter.


Using stress patterns correctly is a major part of the battle in getting people to understand your accent. American English speakers listen to the stress patterns of your syllables in order to figure out which words you're saying, but if you are stressing syllables in ways they aren't used to, they will struggle to understand you. Hindi speakers not only tend to speak in a way that is less stress-timed than native speakers of American English, but they also use pitch very differently, which is part of the reason why Indian accents are considered very difficult to understand by many speakers of other dialects of English. If you put in the time to practice stressing and unstressing your syllables like American English speakers, it will really pay off and Americans will find you much easier to understand.
