Convert text into the NATO/ICAO phonetic alphabet for clear spelling over radio and phone. Handles digits, punctuation and case, with a full reference table.
Spell anything out using the NATO phonetic alphabet. Useful when you have to read a serial number, licence plate or password aloud over a bad phone line. Letters map to Alfa, Bravo, Charlie; digits and common punctuation are spelled out too.
Over a noisy radio channel, B, C, D, E, G, P, T, V and Z all sound nearly identical. A spelling alphabet replaces each letter with a word chosen to be unmistakable even when half the frequencies are lost. Confusing a B for a D in a call sign or a grid reference has caused real accidents, which is why aviation and maritime services mandate its use.
The current set was adopted by the International Civil Aviation Organization in 1956 after several years of testing across speakers of different native languages. NATO adopted the same list, which is why it carries both names. Each word was selected for intelligibility across English, French and Spanish speakers, and the list survived precisely because it tested well under degraded audio.
ph digraph is not pronounced as f in many languages.nein and from five over a poor line.Say the letter, then the word: "B as in Bravo". When reading a mixed string, group it: a licence plate AB-12-CD is read "Alfa Bravo, One Two, Charlie Delta". For case-sensitive material such as passwords or API keys, say "capital" before the letter. Enable the Mark capitals option here to render upper-case source letters in upper case so you can see where those markers belong.
