The following example demonstrates the RejectThreshold property that is used in a PhoneApplication Speech Control. This example is based on the Speech ServerPhone Number sample.

<script language="jscript">
  //formatting the area code part to look like: (NNN)
  function FormatAC(theValue){ 
    if(theValue == null) 
      return; 
    else { 
      var sAC = "(" + theValue.value + ")"; 
      document.all.tbPhone.value = sAC + document.all.tbPhone.value;
    } 
  } 
  //formatting the area code part to look like: NNN NNNN 
  function FormatLN(theValue){ 
    var sLN = theValue.value; 
    if(sLN == null || sLN.length != 7) 
      return;                 
    else {            
      var re = /(\d{3})(\d{4})/;                   
      var aMatchCollection = sLN.match(re);                     
      sLN = aMatchCollection[1] + " " + aMatchCollection[2]; 
      document.all.tbPhone.value = document.all.tbPhone.value + " " + sLN;                   
    } 
  } 
  //formatting the extension part to look like: xNNNN
  function FormatEXT(theValue){ 
    if(theValue.value == "") 
      return; 
    else { 
      var sEXT = "x" + theValue.value; 
      document.all.tbPhone.value = document.all.tbPhone.value + " " + sEXT;
