A voice reads all my messages!

Sep 11, 2014

I recently upgraded to MIUI v6, and now, every time I receive a message (SMS), a voice reads it through the speaker.
I heard about the Car/Drive mode that has this functionality, but I can't find it...

How could I disable it? The only way I have found is to turn down the volume, but if I forget to do it, my messages are read in public, which bothers me a little!

Thanks in advance!
