AviaVox continuously adds new languages to their systems. Basically, there are no limitations to the number that AviaVox can build in their systems, although it needs to be said that the driver for making new languages are the requirements at an airport or airline. Amongst the many languages that AviaVox can support, one will find for instance:
British-English, French, German, Dutch, Flemish, Spanish, Portuguese, Italian, Greek, Polish, Russian, Danish, Norwegian, Swedish, Egyptian Arabic, Modern Standard Arabic, Hindi, Mahrati, Mandarin, Japanese, Korean.
Any other language can be added.
