SpeechLib works fine in editor but not in runtime

Hi,

I am trying to use SpeechLib to implement Text-To-Speech in Unity, it works fine in the editor but I get an exception when running a build on windows.

Here is my script :

Code (CSharp):

1. using UnityEngine;
2. using SpeechLib;
3.  
4. public class TTS : MonoBehaviour
5. {
6.     private SpVoiceClass voice;
7.  
8.     private void Start()
9.     {
10.         voice = new SpVoiceClass();
11.     }
12.  
13.  
14.     // Use this for initialization
15.     void Update()
16.     {
17.         if (Input.anyKeyDown)
18.         {
19.             voice.Speak("TEST");
20.         }
21.     }
22. }

And the logs :


NotSupportedException: Specified method is not supported.
at System.__ComObject..ctor () [0x00006] in <c79628fadf574d3a8feae0871fad28ef>:0
at (wrapper cominterop) SpeechLib.SpVoiceClass..ctor()
at TTS.Start () [0x00001] in C:\Users\leosa\OneDrive\Documents\TTS\Assets\Scripts\TTS.cs:12

 

I am having exactly the same problem. Have you found a solution?

 

Is there any updates? I am facing same problem.

 

I found the solution.

Steps:

1. Build Settings
2. Player Settings
3. Make sure you selected "Standalone" tab
4. Open "Other Settings" tab
5. Api Compatibility Level: choose .Net 4.x
6. Save and build
