TeleSpell

A word for every letter.

Spelling alphabets, custom codewords, and spoken playback for iPhone and Mac.

Try spelling a name

01 Letter by letter

A name, spelled clearly.

On a call, B can sound like D. Bravo and Delta give each letter a word of its own. Try a name or a booking code.

NATO alphabet

Your text

This example uses NATO letters, Niner for 9 and names for other numbers and punctuation. An accent is named after its letter. Other characters stay as typed.

Try up to 24 characters. Nothing you type is saved or sent.

What does Clarity Score tell you?

It helps you review phrase ambiguity and the distinctiveness of an alphabet. The diagnostics flag issues such as short codewords, missing symbols, and similar-sounding mappings. It is a practical guide to review, not a guarantee that a phrase will be understood.

What can I export?

Pro includes CSV batch export for scripts and documents, and audio bundles for offline distribution.
