Method and worked example
Words are extracted with browser word segmentation when available and a Unicode-aware fallback otherwise. Hyphenated components are counted separately. A compact reviewed exception map handles common irregular words; remaining words use vowel groups, silent-e handling, and a small ending adjustment.
Example
“Hello beautiful people” is estimated as seven syllables: hello (2), beautiful (3), and people (2). Punctuation is ignored. “Mother-in-law” is treated as hyphenated components.
Limits and interpretation
English spelling does not uniquely determine pronunciation. Proper names, regional pronunciations, acronyms, foreign-language words, invented words, and words such as “fire” may reasonably be spoken with different syllable counts. The tool accepts up to 5,000,000 characters and labels its result as an estimate.
Safe local processing
All submitted content is treated as plain text. The tool uses text nodes and safe DOM APIs for results. It does not render pasted markup, call an AI service, request a remote text-processing API, or store drafts for later use.
