Vowel Count Tool
Count ASCII vowels a, e, i, o and u case-insensitively in text.
Description
Count ASCII a, e, i, o, and u occurrences case-insensitively.
This explicit letter count is useful for teaching, word games, and simple text statistics; it measures spelling rather than pronunciation.
When to use Vowel Counter
- Check a classroom or word-game exercise
- Compare vowel density
- Build a simple text statistic
How the calculation works
A case-insensitive expression counts every occurrence of a, e, i, o, or u. Repeated vowels each contribute once.
Interpreting the result
The result is not a syllable count. Y and accented vowels are excluded unless text is transformed first.
Important limitations
- Only unaccented ASCII vowels count.
- Silent letters and language-specific vowels are not modeled.
