@M-Schrijver said in How to change the horrible robotic voice when navigating with Android phone?:
Those are variants (speed corrections) of the standard Google Engine which are also selectable in the Android settings.
I cannot argue about your phone, but on mine that is definitely not true. In the Android settings I have no choice in voices whatsoever. In the app I get to choose between 11 Dutch voices. Some of them really sound alike. but not all. Voice 1 is the standard android voice which Google Maps also uses. I guess that this is the one you call "robotic". I prefere Voice 11, a naturally speaking female voice. Voice 10 is a naturally speaking male voice.
This recording shows 3 completely different voices:
