The Spanish syllable splitter breaks Spanish text into syllables word by word and highlights each word's stressed syllable in red bold, making Spanish stress rules visible at a glance. Clicking any word plays that word through the browser's speech synthesis. This is especially useful for learners who can read Spanish but struggle to predict where the stress falls.
How Spanish stress rules work
Spanish has three predictable stress rules that the tool applies automatically:
- Words ending in a vowel, n, or s default to stress on the second-to-last syllable
- Words ending in any other consonant default to stress on the last syllable
- A written accent mark (
á é í ó ú) overrides both rules — whichever syllable carries it is always stressed
Syllable split examples
Buenos días splits as:
- Bue-nos — ends in s, default stress on second-to-last →
Bueis stressed - Dí-as — accent mark on
Díoverrides the default →Díis stressed
Blancanieves (6 syllables):
- Blan-ca-nie-ves — ends in s, stress on second-to-last →
nieis stressed
Ciudad (2 syllables):
- ciu-dad — ends in d (not a vowel/n/s), stress defaults to the last syllable →
dadis stressed
When the audio button produces no sound
The pronunciation feature uses the browser's Web Speech API with es-ES as the preferred voice. On Windows and Android, Spanish voice data is not installed by default. If clicking a word produces no audio and no error, the device has no Spanish TTS voice installed. Download the Spanish language pack from your OS language settings. iOS Safari typically has Spanish voices built in and works reliably.
Getting the most from this tool
Paste up to around 200 characters at a time for the smoothest experience — very long passages cause a brief layout delay while the page renders all the syllable annotations. Numbers and punctuation are preserved in the output but are not analyzed. Foreign words or proper nouns borrowed into Spanish may not follow the standard stress rules and should be verified separately.
