Caller name talker

AC Question

When my note 4 was on lollipop 5.1.1 I was able to use an app to have callers names announced. Since moving to marshmallow 6.1 I find this impossible. Caller Name Talker says it works with 6 provided you give permissions when first open the app, but it does not work for me on 6.1 Does anyone have an answer to my problem? I have ringtones allocated to some contacts but that is not possible for all.
