Data Source & Methodology
We implement the NATO/ICAO phonetic alphabet as defined by the International Civil Aviation Organization (ICAO Doc 4444) and allied military communications guides. Digit pronunciations follow ITU-T Recommendation E.161. Punctuation call-outs mirror common aviation phraseology (Dash, Period, Question mark, etc.).
How It Works
- Normalize the input to uppercase letters while preserving accents and punctuation.
- Map each character to its call sign. Space characters become “/” to highlight word boundaries.
- Combine call signs into a single string for quick radio spelling, while also listing the per-character breakdown.
Worked Example
Input: QA-137
- Q →
Quebec - A →
Alfa - - →
Dash - 1 →
One - 3 →

Seven
Output: Quebec Alfa Dash One Three Seven
Frequently Asked Questions

Yes. It matches the NATO/ICAO alphabet used worldwide for aviation, maritime, and emergency communications.
Why is “Alfa” spelled without the ph?
The ICAO standard spells Alfa and Juliett to ensure consistent pronunciation by non-native English speakers.
