Provide voice language options separately and independently from main app language:
So can select the same or different App vs Voice languages with all possible combinations.
Bonus: we will be able to add quickly extra voice languages without have to translate simultaneously the whole app (not trivial task).
If have need for more voice languages, please inform us.
Voice language options are coming in next version:
Where can I report wrong voice guidances in Czech voice? Here?
Can report any language improvements here.
Route missed is badly converted to Cz.
And how the “Route missed” is translated more nicely in Czech?
Or if know Czech well, we can send you some texts and can help us with the translation. 
Sure, send me it, I like to help you.
Thanks, I sent you a message with the texts.
If someone else wants to help us improve the other voice languages (Italian, Polish, Swedish), please report here.
Wouldn’t it be easier to add a link to one of those crowdsource translation pages so that we can see the status and vote in translations of others etc?
Currently there aren’t resources in public for translation (and they’re many).
We have thought of that, but need to organize it carefully first.
As changes to be validated / integrated in a developer friendly way is an important factor.
For the record the resources for translation are a large collection of text files.

All voice languages are clearly mentioned in app description.
More voice languages may come in future if there is interest.
