Lost Voice Data that works with Pico TTs

[Berry-well]

Fairly new to Android phone.
Recently received prompt to intsall latest update.
However, after doing so lost voice data app that works with pico TSS on phone. :'( The voice data synthesis allows all incoming calls to be announced audibly instead of ring tones. I have lost the feature and cannot seem to get it back. I did go out to market; cannot find what I had. There are a couple out there is anyone aware of any that are considered good and will once again announce my callers by name?...
