Syllable Stress Checker
Find the stressed syllable in any English word — instant IPA and audio pronunciation.
Same root word, completely different rhythm. This syllable stress checker tells you exactly which syllable carries the stress in any English word, breaks it down phonetically, and — for words like record or present that change meaning depending on stress — shows you both pronunciations side by side.
How to Use the Stress Checker
- Type a word into the box above. One word at a time works best — this isn’t built for full sentences.
- Select “Check Stress.” The stressed syllable appears in uppercase and in color.
- Read the IPA transcription underneath, which shows the exact sound and stress marks a dictionary would use.
- Tap the speaker icon to hear the word, using your browser’s built-in voice.
- If the word has two valid pronunciations depending on meaning, you’ll see both, with a short example sentence for each.
How Word Stress Works in English
Here’s the part that surprises a lot of learners: English stress isn’t spelled out anywhere in the word itself. French tends to land stress on the last syllable. Polish almost always stresses the second-to-last. English has no such rule. Record the noun and record the verb are spelled identically and stressed completely differently, with no visual clue on the page to tell you which one you’re looking at.
That’s why this tool doesn’t try to guess stress from spelling patterns — it looks the word up. Every syllable is built around a vowel sound (the nucleus), and one of those vowels gets more emphasis, more length, and a clearer sound than the rest. Consonants around it barely matter for stress; the vowel does the work. Once you can identify where that vowel sits and which one is loudest, you’ve identified the stress pattern.
Primary vs. Secondary Stress
Longer words often carry two levels of emphasis. Take a four-syllable word like “photographic.” The strongest beat — primary stress — falls on the third syllable: pho-to-GRAPH-ic. The first syllable isn’t fully flat either; it gets a secondary stress, weaker than the primary beat but still stronger than the two weak syllables in between.
Dictionaries mark this with two symbols: ˈ before the syllable with the main stress, and a lower ˌ for the secondary one. This tool follows the same convention, so a word like “information” shows up as /ˌɪnfərˈmeɪʃən/ — weak, weak, strong, weak, with that lighter secondary mark up front.
Worked Examples
Photograph → Photographic
Watch what happens to stress as you add suffixes to the same root:
- PHO-to-graph — stress on the first syllable
- pho-TOG-ra-phy — stress moves to the second syllable
- pho-to-GRAPH-ic — stress moves again, to the third
Nothing about the spelling warns you this is coming. The suffix “-ic” pulls stress toward itself in most cases (compare economy → economic). It’s a pattern worth knowing, but not one most textbooks spell out clearly.
Banana and Umbrella
Not every multi-syllable word puts its strongest beat at the start. Both of these stress the middle syllable — ba-NA-na, um-BREL-la — which is one reason speakers new to English sometimes flatten them out or guess wrong on the first try. There’s no shortcut beyond hearing it, which is exactly what the audio button is for.
When Stress Changes Meaning
A small set of English words change their part of speech depending on where the stress lands. Say “record” as REC-ord and you’re talking about a noun — a written record, a vinyl record. Say it as re-CORD and you’ve switched to a verb: to record something. The spelling never changes. Only the rhythm does.
- PRES-ent (a gift) vs. pre-SENT (to present a report)
- OB-ject (a physical object) vs. ob-JECT (to object to something)
- CON-tract (a signed agreement) vs. con-TRACT (metal will contract as it cools)
This tool checks every word you type against a curated list of roughly 40 of these noun/verb pairs and shows both forms automatically, each with a short sentence so the difference is obvious in context rather than just in theory.
Why Some Words Aren’t in the Dictionary
The stress data comes from a real pronunciation dictionary covering the common core of English vocabulary. It doesn’t cover every brand name, surname, or word someone invented last week. If you type something and get no result, that’s usually why. For genuinely new vocabulary or names, your best options are a live speaker, an audio dictionary entry if one exists, or trusting your ear on a recording.
Frequently Asked Questions
How is the stress pattern decided for each word?
The tool checks the word against a pronunciation dictionary of more than 117,000 English words and reads the stress marks already assigned to each syllable, rather than applying spelling rules that don’t reliably predict English stress.
What’s the difference between primary and secondary stress?
Primary stress is the strongest, most prominent syllable in a word — the one you’d naturally say loudest. Secondary stress is a smaller emphasis elsewhere in the same word, still stronger than the unstressed syllables around it but weaker than the primary beat.
Why does a word like “present” show two different pronunciations?
Some English words shift stress depending on whether they’re being used as a noun or a verb. The spelling stays identical; only the emphasis moves. This tool flags those words and shows both readings side by side.
Can I hear the word instead of just reading the stress marks?
Yes. Tap the speaker icon next to any result and your browser’s built-in voice will pronounce the word aloud.
Is this useful for poetry, not just single words?
It helps. Knowing where stress naturally falls in individual words is the foundation for scansion — reading a line of poetry for its meter, whether that’s a strict iambic pattern or something looser. This tool checks one word at a time rather than full lines, but the syllable and stress data behind it is the same data a meter-checking tool would need.
