Hands-free/Driving Mode: How to change the reading voice's language (and voice: male/female etc...)? Is there a way to change the language and voice for reading out the information on hands-free mode. Even better, it would be nice if the language and voice for the alarm could be set on a per-alarm feature. Anyone knowing if and how this can be done, please don't hesitate to reply.

Thanks.
Go to settings > language and input > text to speech output.

There you can select one of your installed voices.
You can install voices from the Play Store.
My personal best and free is IVONA (https://play.google.com/store/apps/details?id=com.ivona.tts&amp;hl=de)
