Spelling Alphabet

Convert text to phonetic spelling-alphabet code words.

A spelling alphabet replaces each letter with an unambiguous code word so it can be read aloud over a noisy channel. This tool converts text to code words and decodes them back. Pick an alphabet below: NATO/ICAO is the modern international standard, and the others cover historical and regional variants. When decoding, separate code words with spaces (for example, Golf Echo Oscar).

When decrypting, separate code words with spaces (example: GOLF ECHO OSCAR).
