nomatch tag not working

[davisco]

I am having problems with the <nomatch> tag. What I am trying to do is fairly basic - in pseudocode:

Code: Select all

prompt: You are about to clock in.  To confirm, press 1. To cancel and return to the main menu, press 2.
if( 1) 
   prompt: please wait while I clock you in.
else if( 2)
   goto #mainMenu
nomatch
   prompt: Invalid response.
   reprompt
noinput
   reprompt
// fall through for processing login here

menu: mainMenu
   stuff.
end pseudocode -----

The 1 and 2 work fine. The problem is that seemingly no matter what I do, pressing anything other than 1 or 2 seems to fall through just like 1. As I understand it the nomatch should pick it up and do a reprompt.

Here is one version of my actual code from a scratchpad.

Code: Select all

<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://www.w3.org/2001/vxml 
   http://www.w3.org/TR/voicexml20/vxml.xsd"> 

   <form id="clockIn">
      <field name="clockInChoice" type="digits">
         <grammar type="application/x-jsgf" mode="dtmf">
            1|2
         </grammar>		
         <prompt>
            <voice name="mike" xml:lang="us_en" gender="male">
	       You are about to Clock In. 
	       To confirm, press 1.
	       To cancel and return to the menu, press 2.
	    </voice>
         </prompt>
	 <filled>
	    <if cond="clockInChoice=='1'">
	       Please wait while I clock you in.
	    <elseif cond="clockInChoice=='2'"/>
	       <goto next="#mainMenu"/>
            <else />
               <clear namelist="clockInChoice"/>
	    </if>
	  </filled>
          <nomatch>
             Your response was not valid.  Please try again.
             <reprompt/>
          </nomatch>
          <noinput>
             <reprompt/>
          </noinput>
      </field>
      <block>
	 <log label="Test">In form clockIn</log>
      </block>
   </form>

<menu id="mainMenu">
   <prompt>
      Main Menu - Goodbye
   </prompt>
</menu>

</vxml>

I have also tried the code above with a different grammar:

Code: Select all

         
		<grammar type="application/srgs+xml" root="ROOT" mode="dtmf">
			<rule id="ROOT">
				<one-of>
					<item>1</item>
					<item>2</item>
				</one-of>
			</rule>
		</grammar>

This has the same failure.

I have also tried another implementation taken from the vxml documentation for the <option> tag with the nomatch added in and the prompts changed for my needs.

Code: Select all

<?xml version="1.0"?>
<vxml version="2.0">
  <form>
    <field name="clockInChoice" type="digits">
      <prompt>
        You are about to Clock In.
        <enumerate>
          To <value expr="_prompt"/>, press <value expr="_dtmf"/>.
        </enumerate>
      </prompt>
      <option value="confirm" dtmf="1"> confirm </option>
      <option value="cancel" dtmf="2"> cancel and return to the main menu </option>
      <filled>
        You chose <value expr="clockInChoice"/>.
        <if cond="clockInChoice=='cancel'">
           <goto next="#mainMenu"/>
        </if>
      </filled>
      <nomatch>
          oops... Wrong selection. 
          <reprompt/>
      </nomatch>
    </field>
    <block>
        <prompt>
           Now processing clock in.
        </prompt>
    </block>
  </form>

This also seems to be ignoring the nomatch tag.

I'm sure its something I'm not handling correctly but any advice would be appreciated.

Thanks

Hi,

The error was with the line (in your first script):

Code: Select all

<field name="clockInChoice" type="digits">

Should be changed to:

Code: Select all

<field name="clockInChoice">

Reason being that setting type="digits" defines the build-in digits grammar, which will accept any number of digits as valid input. Therefore, if you entered any numbers at all, your <else/> block would be hit in the <filled> block, and a nomatch would never occur. If you remove this, then the only grammar that will be applied to the field will be the grammar you have defined as 1 or 2.

Please let us know if you have any questions.

Thanks! That was it! I thought that was specifying dtmf -vs- voice. Didn't realize it was overriding the rule I was adding in.
Thanks again.
