It’s not included in the search log and there isn’t any official announcement, but the careful observations of one user made us realize that there has been a slight modification in the Search voice that responds to our “Ok Google” queries. We’re not really sure if it makes any difference, although psychologically speaking, it may have an impact on people who don’t really like talking to someone who sounds like a robot (even if technically, they may very well be one).
If you compare the voice from the Samsung Galaxy S6, which is running on Android 5.1.1 Lollipop and the new Galaxy S7, which of course has Android 6.0.1 Marshmallow, you’ll hear the slight difference that Google has made to the search assistant. The latter sounds a bit more natural than the more robotic tones of the former. It is a subtle change, but as we said, it may impact users subconsciously since talking to what sounds like a “real person” is always better than listening to an automated voice.
Based on the same comparison video as well, it seems that there is a very slight lag time in the search results for Marshmallow since it looks like the Galaxy S6 responded faster, even if they were both on WiFi. Hopefully, this is just a bug and that it will be fixed by the next minor update.
And if you didn’t know it yet, you can actually change the accent and dialect of your search assistant, if you don’t feel like using the default woman. Just go to Settings > Language and input > Google Voice Typing > Languages and then long press an option just to hear what it sounds like before choosing one.
