I'm following the instructions in
https://msdn.microsoft.com/en-us/library/office/hh361572(v=office.14).aspx but after installing the runtime, the voice, and the SDK, I couldn't figure out how to reference the Microsoft.Speech.Synthesis namespace on my Windows 7-64 bit machine with Visual Studio 2013 community edition update 4.
What's the real purpose of the SDK and how do I configure.
The installers are 64bit versions, and the voice synthesis works
PS: If you really think that my question is unappropriate here, please just put it in the comments or answers and suggest me where should I put it. I'll b glad move it far from your judgement in less than 10 hours
I believe you need to use C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Speech.dll (for whichever .NET version is appropriate). It is a wrapper around Microsoft.Speech.dll. I was having problems selecting the voice, but it turned out to be just build configuration.
