This is an online utility that will phoneticise any text that you enter in the above box
It means that you get a list of letters in the NATO phonetic alphabet (also known as the international radiotelephony spelling alphabet), and names of any other symbols/characters that aren't in that.
It is useful for spelling out words and phrases to people to prevent mis-spelling, especially over the phone.
I originally wrote this for a limited company formation agent who take a lot of orders over the phone. People ask them to form new companies and this makes it easier for them to confirm the spelling of the company names and other details over the phone
There should be a programming library (in .NET) and possibly a web service (SOAP) available for you to use soon so you can integrate this into your own programs/websites
