This paper presents an online grapheme to phoneme converter for European Portuguese named grafone. This converter implements a hybrid approach that includes linguistics information (phonological context, stress vowel, etc.) in a statistical algorithm that learns from examples and creates a model. It can convert any grapheme sequence but uses an exception dictionary with about forty thousand with the most frequent words in CETEMPúblico corpus. The results can be displayed in the phonetic alphabets IPA or SAMPA and the grapheme can be synthesized, for now using Google Translate engine. The converter is available online, can be used without limitation and all related resources can be downloaded without any restriction.
