Weather Talker keeping the same voice

Ok I have a few voices loaded by each time I select a voice it works until it reboots or WD goes down. Then it defaults back to the first one in the list. Now I noticed in the WDISPLAY.ini that the selected speech voice is 1 but I was not sure if it was picking the first one in the stack. Second part if you change the voice update freq=30 to 60 it would do it every hour? Or am I wrong there? I know it does not show on the screen since the max is 30min frequency, but if you change in INI file would it work? Thanks

selected speech voice=1
file name=talking.wav
file name new=talkingnew.wav
start hour=8
stop hour=22
voice update freq=60
file update freq=30
