SpeechLib.SpVoiceClass:GetVoices does crash my Unity executable

Questions & Answers

I created a project with Unity (version 4.5.3f3).
I only wrote a simple script as follow:

using UnityEngine;
    using System.Collections;
    using SpeechLib;
 
    public class SpeechTest : MonoBehaviour
    {
        private SpVoice voice;
 
        void Start()
        {
            voice = new SpVoice();
            ISpeechObjectTokens voices = voice.GetVoices();
        }
 
        // Update is called once per frame
        void Update()
        {
            if (Input.anyKeyDown)
            {
                voice.Speak("Hello, world!", SpeechVoiceSpeakFlags.SVSFlagsAsync);
            }
        }
    }

Here you can download the test project for Unity: https://dl.dropboxusercontent.com/u/12184013/TextToSpeech.zip

When I try to play (in Unity editor), the game runs without problems.
Instead, when I build and run the game, I receive a message error:

The game crashed. The crash report
folder named “2014-09-12_013622” next
to game executable. It would be great
if you’d send it to the developer of
the game!

When i comment this line

    ISpeechObjectTokens voices = voice.GetVoices();

the game doesn’t crash after I rebuilt it.

I need to call GetVoices method, because I want to set a new voice in the “SpVoice voice” object.

Thanks in advance to everybody!

Here is the solution: http://forum.unity3d.com/threads/speechlib-spvoiceclass-getvoices-does-crash-my-unity-executable.268011/#post-1772720

In a nutshell the library [Unity Install Directory]\Editor\Data\Mono\lib\mono\2.0\CustomMarshalers.dll should be included in the Unity project (adding it as a asset).
