Functions have to be in a class. I’ve updated the zip to contain working code. Feel free to re-download. You can also just put those lines you added into a new class by doing this (That class can live right where you put the functions):
public static class Utility
{
public static Coroutine ExecuteLater(this MonoBehaviour behaviour, float delay, System.Action fn)
{
return behaviour.StartCoroutine(_realExecute(delay, fn));
}
static IEnumerator _realExecute(float delay, System.Action fn)
{
yield return new WaitForSeconds(delay);
fn();
}
}

I am facing similar problem as @Alex L,

However, after removing the lines below
//if (Timeline.theTimeline.QReprocessingEvents)
// return;

And adding the code below to a line before public class WindowsVoice : MonoBehaviour { class}, I still get errors.

public static Coroutine ExecuteLater(this MonoBehaviour behaviour, float delay, System.Action fn)
{
return behaviour.StartCoroutine(_realExecute(delay, fn));
}
static IEnumerator _realExecute(float delay, System.Action fn)
{
yield return new WaitForSeconds(delay);
fn();
}

Please advise how I can solve this problem,

Thank you.

Top level

When you say “outside the WindowsVoice class” does that mean on the top-level or in another class?

Well, the most common issue that people have is that they are not deploying 64 bit. Double check your build and make sure you picked x64.

but I’m getting
“Member ‘WindowsVoice.speak(string, float)’ cannot be accessed with an instance reference; qualify it with a type name instead [Assembly-CSharp]”

so then I tried
WindowsVoice.speak(“test”);
which compiles but I’m not getting any audio.

Any ideas why? I’m very new to Unity and C# so any help would be appreciated, thank you!

I’m sorry about the problems you are seeing. I uploaded a newer version and created dependencies that shouldn’t be there. I’ll try to get a new version uploaded soon, but for now, you can simply delete the line that references the ‘Timeline’ and the following line. For the second error, add this code outside the WindowsVoice class:
public static Coroutine ExecuteLater(this MonoBehaviour behaviour, float delay, System.Action fn)
{
return behaviour.StartCoroutine(_realExecute(delay, fn));
}
static IEnumerator _realExecute(float delay, System.Action fn)
{
yield return new WaitForSeconds(delay);
fn();
}

I downloaded the finished 64 bits dll and the plugin, and I’m on Unity 2019.4.1f. How would I be able to fix this?
Thanks.

Thanks. Stopping the speech is done in the voice API by calling pVoice->Pause(). I call this only when destroySpeech() is called. In the destroySpeech function, I set shouldTerminate to true which is checked in the thread’s while loop. When the loop exists I call Pause() then Release().

If you want the ability to pause, you could add another member variable that the thread’s while loop checks to pause and then resume later. If you want to cancel something that is being spoken and drop that line entirely you call Pause() then Speak(nullptr, SPF_ASYNC | SPF_PURGEBEFORESPEAK, nullptr)

but I noticed a problem with using it in my game. How would one go about stopping it in the middle of talking?

Thank you
