I would first like to mention that I have been using an iPhone for a while now, since my iOS 4s and iOS 6) I vaguely remember having something similar to this happening or being a choice a long time ago. I recently upgraded my 5c to 9.1 and now every capital letter, instead of just having a slight inflection to denote that it is upper case, says "cap" before saying the letter.
I combed through voice over, speech and puntuation settings. I also turned the pitch on and off, , which also didn't work. I couldn't find out where to turn this off.... Does anyone know the answer to this issue?
