1) You do not have a proper TTS Engine installed in Android. I recommend Google TTS from the Google Play Store.
2) You are missing one or more files from the UX folder, or have a conflict of files.
3) There is something else wrong with your NextGen install or Android device.
Everything I post has been tested by me and working. When it does not work for others I cannot remotely diagnose a problem.
The TTS voice should already work in NextGen as it is..did you try it? Did you just want speedcam announcements added?
I tried every version of every voice file in that thread and could not get any of them to work or even be recognized by NextGen. I suspect they have been heavily modified (more than 3 times the size of other TTS Voice files) and may only work in a particular way with a particular TTS Voice Engine.
You may have to follow the exact steps outlined in the thread to get one to work and/or post in that thread and see if somebody can help.
I admit defeat on this one.
