How to restart thread or any other alternate solution

I am working calling app which automatically calls a number. I am using main thread to query call status(busy,dialing,active, calling, deactivated etc). Whenever call is picked recorded audio will be played using other thread 2. When call status is deactivated main thread will stop audio by stopping thread 2. On next call again when call is picked recorded audio will played using thread 2. 

     Thread autoReminder = new Thread(new ThreadStart(threadAutoCalling));


////   Main thread on call attend calls
 autoReminder.Start();
// On call end, i tried
 autoReminder.Abort();

  private void threadAutoCalling()
        {
            try
            {
               // PlayAudio(@"C:\Users\CheatnPc\Desktop\TextToSpeechAudio\psf1.wav");

                PlayAudio(@"C:\Users\CheatnPc\Desktop\TextToSpeechAudio\psf3.wav");
                PlayAudio(@"C:\Users\CheatnPc\Desktop\TextToSpeechAudio\sales.wav");
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
 public void PlayAudio(string path)
    {

        (new Microsoft.VisualBasic.Devices.Audio()).Play(path, Microsoft.VisualBasic.AudioPlayMode.WaitToComplete);

    }

after thread abort it can not be started again. How can i do this or is there any alternate solution for this.

As I understood correctly you want to abort your play of music. For this reason it is more applicable Task class. You can cancel your Task by calling Cancel() method of class CancellationTokenSource.

Example of console application:

CancellationTokenSource cancellationTokenSource =
        new CancellationTokenSource();
CancellationToken token = cancellationTokenSource.Token;
Task task = Task.Run(() =>
{
   while (!token.IsCancellationRequested)
   {
      ThreadAutoCalling();
   }
   token.ThrowIfCancellationRequested();
}, token);
try
   {
      Console.WriteLine("Press any key to abort the task");
      Console.ReadLine();
      cancellationTokenSource.Cancel();
      task.Wait();
   }
catch (AggregateException e)
{
     Console.WriteLine(e.InnerExceptions[0].Message);
}

Thread's cannot be restarted - when they're done, they're done.

The usual solution would be to simply start a new thread, but when you're doing as little as you are, using a threadpool thread might be a better idea:

Task.Run(threadAutoCalling);

Or even better, if there's an asynchronous way of invoking those PlaySound and Speak, use that - usually, you wouldn't need real CPU work to handle operations like that.
