grammarmaxage

grammarmaxage

Default Value: NULL

Tells the platform the maximum acceptable age, in seconds, of cached grammars. Setting “grammarmaxage” to NULL allows the platform to honor expiration time set by the web server.

Example

<?xml version="1.0"?>
<vxml version="2.0">

  <property name="grammarmaxage" value="150s"/>
  <property name="grammarmaxstale" value="25s"/>

  <form id="name">
    <field name="last_name" type="lastname">
      <prompt>
        Say your last name and spell it.
      </prompt>
    </field>

    <block>
      <prompt>
        Your last name is <value expr="lastname"/>.
      </prompt>
    </block>

  </form>
</vxml>

Explanation

From this example, the “grammarmaxage” value is set to 150 seconds and the “grammarmaxstale” value is set to 25 seconds. This sets a global property that all grammar tags have a maxage value of 150 seconds and a maxstale value of 25 seconds. So, since the file “lastname.php” (remote grammar for the lastname built-in grammar type) is inside of a <grammar> tag, it would have a maxage value of 150 seconds and a maxstale value of 25 seconds because of the “grammarmaxage” and “grammarmaxstale” properties.
