SpeechSynthesizer doesn't get all installed vo

问题:

I have installed a new voice in my Windows 7 32 bits OS in order to be able to use from in one .NET application i'm developing. But when i use GetInstalledVoices() method to view list of all voices, only one (default "Microsoft Anna") appers. Why it may happens?

Voice is appears in Control Panel -> Speech section. Other TTS applications also can use this voice.

Thanks.

I found the answer for my question here

This is a bug in System.Speech.Synthesis and .NET v4.5 solves this problem.
