You've just confirmed that TTS is working and not necessary "TTS Pro" is working. For TTS to announce alerts, that alert text entry must exists in your TTS voice config file. That is there has to be a "translation" made for that alert that matches the default values or the values set in sys.txt The value is correct for Cat 0 that's why you're hearing it. But it might be wrong for Cat 3 "average speedcam" PM me the link to zippyshare.com that you've upload the TTS voice file you're using. BTW, Cat 5 is "Strelka Camera" and Cat 6 is "Railroad Crossing"
