how can add more voices system? have tried installing sapi5 , sapi4 voices link: http://biblprog.com/en/speech_api/voices_sapi/

but not appear in list.

i have gone "text speech" tab in "speech properties" control panel , anna appears on list. not sure why hard.

i using windows 7 64 bit os. ideas?

i want understand how add new voices. want purchase 1 here http://www.textaloud.com/englishaustralian.shtml want make sure work ok.

sapi voices have code, along voice data. matters whether voices 32 or 64 bit. suspect voices downloaded 32 bit voices, , don't show in 64 bit control panel.

you can double-check making sure program compiled "any cpu 32 bit preferred" (or x86 if version of visual studio doesn't support that).
