Speech Synthesis freezes execution in Unity

[Joel_C_]

I recently starting toying with the RealSense's Speech Recognition and Speech Synthesis. 

I've got the Speech Synthesis to work, but when I output the audio, the game freezes execution while the audio is dictated, and then continues running when the audio is complete. I'm using Unity, and I'm calling the VoiceSynthesis.Speak function given with the Unity framework of the SDK. 

Is this a known issue? Has anyone come across this and found a way to get around it?

Fixed it.

I just put all of the speech synthesis in its own separate thread. Works great now!

They provide two scripts in the Unity C# framework that will output the audio. I believe the scripts are called VoiceOut.cs and VoiceSynthesis.cs. Once they're in your project, you can call 
voice_synthesis.cs.VoiceSynthesis.Speak("Voice Synthesis (Nuance* Vocalizer Expressive*)",0,<TEXT TO OUTPUT>,100,100,80);
to output it to audio.
I had to change my API compatibility level from ' .NET 2.0 subset' to '.Net 2.0' in the player settings to remove an error.
