tts_voice object
This method will speak a given string and will pause execution until the string is spoken.
bool speak_wait(string text)
Parameters:
text
The text to speak.
Return value:
true on success, false on failure.
Remarks:
Because script execution is paused while the text inside the speak_wait method is being spoken, it cannot be stopped or interrupted.
Example:

    // Speak some text.

    tts_voice speech;

    void main()
    {
    speech.speak_wait("This is some text.");
    }
