Optimize Speech Recognition

The below code is for Recognizing Speech through wav file.

Currently it takes about 2 to 3 sec to recognize the file. Is there any way to reduce that time.

public void ReadFile(string InputAudioFilePath)
{
PXCMSession session = PXCMSession.CreateInstance();

// session is a PXCMSession instance.
PXCMAudioSource source = session.CreateAudioSource();

// Set the audio fie
PXCMAudioSource.DeviceInfo dinfo = new PXCMAudioSource.DeviceInfo();

dinfo.did = InputAudioFilePath;

// Set the active device
source.SetDevice(dinfo);
PXCMSpeechRecognition sr;
session.CreateImpl<PXCMSpeechRecognition>(out sr);
PXCMSpeechRecognition.ProfileInfo pinfo;

String[] cmds = new String[4] { "Switch On", "Switch Off", "Light On","Light Off" };

// Build the grammar.
sr.BuildGrammarFromStringList(1, cmds, null);

// Set the active grammar.
sr.SetGrammar(1);

sr.QueryProfile(0, out pinfo);
sr.SetProfile(pinfo);
// Set handler
PXCMSpeechRecognition.Handler handler = new PXCMSpeechRecognition.Handler();
handler.onRecognition = OnRecognition;
// Start recognition
var str = sr.StartRec(source, handler);

}
