This counter is built for the way Vietnamese is actually written. Because every syllable is separated by a space, an ordinary word counter reports syllables rather than words. This tool gives you both numbers: the exact count of space-delimited syllable tokens and an estimate of true lexical words.
How it works
Vietnamese orthography separates each syllable, called a tiếng, with a space.
A lexical word, or từ, may be one syllable or a compound of several. The tool
first counts every space-delimited token. It then walks through adjacent pairs
and, when a pair appears in a built-in list of common compounds such as xe đạp
or gia đình, merges them into a single lexical word. Characters and sentences
are counted directly from the text.
Tips and notes
Use the syllable count when you care about layout, typesetting, or character budgets. Use the lexical-word estimate when comparing against an English word count or pricing a translation, since one English word often maps to a Vietnamese compound. The estimate is deliberately conservative: only well-known compounds are merged, so unusual or technical phrases will still count as separate syllables.
