Это мой код для китайского TTS, который не работает в режиме говорения, хотя китайский движок TTS установлен успешно

using Microsoft.Speech.Synthesis;
using System.Globalization;

namespace TTS3
{
    class Program
    {
        static void Main(string[] args)
        {
                //CultureInfo=new CultureInfo("zh-CN");
            SpeechSynthesizer synth = new SpeechSynthesizer();

// Output information about all of the installed voices. 
            foreach (InstalledVoice voice in synth.GetInstalledVoices(new CultureInfo("zh-CN")))
                {
                    synth.SelectVoice(voice.VoiceInfo.Name);
                    //Console.WriteLine(synth.Voice.Description);
                    synth.SetOutputToWaveFile("C:\\Users\\surabhi\\Desktop\\yes.wav");
                    synth.Speak("你好世界");
                    break;
}
            Console.WriteLine();
            Console.WriteLine("Press any key to exit...");
            Console.ReadKey();
        }
    }
}

Исключение составляет код
