The NATO phonetic alphabet, formally the ICAO/NATO spelling alphabet, replaces each letter with an unambiguous code word — Alpha, Bravo, Charlie, and so on. It is used in aviation, the military, emergency services and call centres so that letters survive noisy radio or phone channels without being misheard. This free tool spells any text phonetically and decodes phonetic spellings back to plain letters.
How it works
Each of the 26 letters maps to a fixed code word chosen to be distinct from every other word, even under heavy distortion: B is Bravo (not confusable with D), and M is Mike (not confusable with N). When encoding, the tool looks up each letter and joins the code words with spaces; digits are spelled out as words and spaces become a slash so word boundaries survive.
Decoding reverses the table: each space-separated code word is matched case-insensitively to its letter. Words that are not in the alphabet are passed through in brackets so nothing is lost.
Example
Spelling the name GERA phonetically gives Golf Echo Romeo Alpha. To confirm a postcode like SW1A you would read Sierra Whiskey One Alpha. Decoding Tango Echo Sierra Tango returns TEST.
