Im using the Voice_TTS-nua-eng-Joe-2.zip file but same results with others that Ive tried. Im also getting the phrase "Slow Down" when approaching speedcam even though Im not speeding. Using Svox /Victoria speech engine. As previously mentioned TTS seems to be fine apart from this.
Are these 2 lines required in sys.txt
say_camera_distance=1
say_camera_speed_limit=1

Also the volume is too quiet over headphones. Volume is fine over Primo through my crash helmet headphone speakers but Nextgen only outputs about half that volume in comparison
