  Hi to all,

  i'm pretty new in Microsoft Speech SDK, and i'm developing a simple application. I'm writing my SRGS grammar using XML language, and i need to catch the confidence score of the single recognized words. I've undestood how to use the semantic <tag> and objects, attributes and methods inside it, but the attribute meta.current().score is always set to 1. It seems like every score of every rule is set to 1. I post my simple test code to show what happens:

  <?xml version="1.0" encoding="utf-8" ?>
  
  <grammar version="1.0"
           xmlns="http://www.w3.org/2001/06/grammar"
           xml:lang="en-US"
           tag-format="semantics/1.0"
           root="main"
           mode="voice">
  
    	<rule id="main" scope="public">
  		<one-of>
  	        <item><ruleref uri="#what"/><tag>out = rules.what</tag></item>
  		</one-of>
  	</rule>
  	
  	<rule id="what" scope="public">
  		<item>what
  		<tag>out = meta.current().score
  		</tag></item>
  	</rule>
  
  </grammar>
