OK sorry but I am totally green as for that so sorry even if it sounds that the answer to my question has already been answered... so...

igo gift android - need this one because I think it is the fastest for my device, android and truck navigation.

1. Configure google TTS on the device - done it I hear the voice, can use it on chrome and pdf reader, but the intonation lacks a lot I must say...
2. Download the above files and insert them to the IGO folders???
3. get a TTS language file for my IGO version/google vocaliser (but I can't find one??) or is there a language there in the pack my Polish friends uploaded?

I have been reading the forum for 3 days I am nowhere....

I understand that there are different vocalisers but I can't understand, does each of the vocaliser need an individual tts voice file for igo? or can I use any tts file? I cant see any TTS voice for Polish language in the voice packs uploaded on the forum...

thank you
