if (e.Result == null) return;
RecognitionResult result = e.Result;
Console.WriteLine("Grammar({0}): {1}",
result.Grammar.Name, result.Text);
if (e.Result.Audio != null)
{
RecognizedAudio audio = e.Result.Audio;
Console.WriteLine(" start time: {0}", audio.StartTime);
Console.WriteLine(" encoding format: {0}", audio.Format.EncodingFormat);
Console.WriteLine(" position: {0}, duration: {1}",
audio.AudioPosition, audio.Duration);
}
