From the developer:
PhonetiKey allows you to type easily IPA (International Phonetic Alphabet) symbols for the English, German, French, Spanish, Italian, Portuguese, Japanese, Korean, Chinese, Arabic, and Russian languages. It doesn't convert regular text into its phonetic representation automatically. What PhonetiKey does is allow you to enter IPA symbols for the supported languages more quickly and easily.
