Aarg! I'm at my wits end trying to get voices on my phatbox on Vista. Hopefully someone is still reading here.. I've read and read, installed and uninstalled and uninstalled ad infinitum and always end up with 'speak failed'. The installs have all been basically what is said to do in this thread.
There are perhaps a few clarifications that may help me give a go at another rounds of install. The hacked AT&T installer, I got it from
www.brianjonesphotography.com/phat/ATTvoicehack.msi , is it possible this is specific to the version of PMM you are using. I have in general been starting with my original Music Manager 1.87, I copied the contents to the hard disk co I could mary the compatibilit w/XP settings? If so, I suppose the path to follow would be to hack my specific msi when it pops up in the install directory.
There are some later versions of music and media manager at phatnoise.us. If I use the 'full install' versions, will they include the natural voices? Tried the same process with them ending in 'speak failed'.
My last effort was to include the Speech SDK, same result. Is it possible there is some problem with my sound hardware, there are no problems found in device manager and everything seems to be working fine. Even the MS voices yield the speak failed in PMM.
