Testing for DTMF in HMIHY grammars

  Does anyone have any experience with HMIHY conversational grammars?

   

  The following code is from a Microsoft example but I don't see how to set a name for the DTMF part of a HMIHY grammar. The test for "KC_ReportPayment" is supposedly testing for the DTMF value (1 in this case) but I don't seem to find a place to assign the "KC_ReportPayment" to the DTMF value of 1.

   

  The test shown below for DTMF fails.

   

  Though when I use DTMF the else if part will return true so things will work.

   

  I'm wondering if this is just a deprecated way of doing this.

   

   

  private void reportPayment(object sender,

                             ConditionalEventArgs e)

  {

      // Test for a DTMF match.

      if (routeCall.RecognitionResult.

          Semantics.ContainsKey("KC_ReportPayment"))

      {

          e.Result = true;

      }

   

      // Test for a speech match.

      else if (routeCall.RecognitionResult.

               Semantics.ContainsKey("HMIHY")  

                   &&

               routeCall.RecognitionResult.

               Semantics["HMIHY"].Value.ToString().

               Equals("ReportPayment"))

      {

          e.Result = true;

      }

   

      // No match.

      else

      {

          e.Result = false;

      }

  }
