Updated 24-Mar-23 16:23pm

C#
SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
Grammar gr = new DictationGrammar();
sre.LoadGrammar(gr);
sre.SetInputToWaveFile("C:\\Users\\Soham Dasgupta\\Downloads\\Podcasts\\Engadget_Podcast_353.wav");
sre.BabbleTimeout = new TimeSpan(Int32.MaxValue);
sre.InitialSilenceTimeout = new TimeSpan(Int32.MaxValue);
sre.EndSilenceTimeout = new TimeSpan(100000000);
sre.EndSilenceTimeoutAmbiguous = new TimeSpan(100000000); 

StringBuilder sb = new StringBuilder();
while (true)
{
    try
    {
        var recText = sre.Recognize();
        if (recText == null)
        {               
            break;
        }

        sb.Append(recText.Text);
    }
    catch (Exception ex)
    {   
        //handle exception      
        //...

        break;
    }
}
return sb.ToString();
