Audio announcements / descriptions

Hi,

Running KODI 16.1 on MacOS 10.11.

An add-on (NASA app) crashed and in trying to quit out I’ve somehow managed to turn on audio descriptions when I navigate around KODI. In the OS settings the audio accessibility setting is turned off but if I turn it on, it’s a different voice to that when I navigate around KODI so I assume it’s a setting in KODI.
I’ve searched the forum and glen through the settings again and again but can’t see how to turn it off. Could someone point me in the right direction please?

Many thanks
