Text to speech won’t be coming to Camtasia 8. It’s out of production and won’t be updated. It won't receive any new features either.
However, if you want a good Text to Speech program. Consider this one.
I can understand why TechSmith doesn’t offer a 32-bit version of Camtasia 9.
32 bit operating systems are becoming antiquated. Most software companies are abandoning the platform.Regards,Joe
