Iphone 6S not reading notifications?

Good morning, since up grading to Ios 10 my 6S only reads the name of the first incoming caller or labelled alarm from the locked screen? When say an alarm goes off voice over says sort of half of the first word of the label and then shuts up. If I use the phone and locks the screen again the same thing repeats itself, only the first notification are read. My brother-in-law and Sister uses the Iphone SE. and do not have the same problem.
Have a good Wednesday!
