Count vowels, consonants, digits, spaces, and see full character frequency analysis.
A vowel counter analyzes text at the character level, giving you a complete breakdown of vowels, consonants, digits, spaces, and special characters. This might seem like a simple tool, but it has surprising practical applications in linguistics, cryptography, education, and content analysis.
In the English alphabet, there are 26 letters. Five of them are vowels: A, E, I, O, U. The remaining 21 letters are consonants. Vowels are speech sounds produced without any significant constriction of the vocal tract — they are the "open" sounds that form the core of syllables.
Consonants, in contrast, involve some form of constriction or closure in the vocal tract. Every syllable must contain at least one vowel, which is why vowels are so essential to language.
According to letter frequency analysis of large English text corpora, the most common letters are:
This distribution is so reliable that it forms the basis of classic cryptographic attacks — frequency analysis. If you see a letter appearing ~12% of the time in an encrypted text, it is very likely the letter "E".
