Supported GRXML Syntax

Voicegain ASR supports the following tag formats in GRXML:

• tag-format="semantics/1.0"
• tag-format="semantics/1.0-literals"

We currently do not support tag-format="swi-semantics/1.0".  We do have workarounds that allow use of swi-semantics/1.0 grammars with no or minimal modifications.

Attached is a complete large grammar with tag-format="semantics/1.0" that works with Voicegain ASR.

Here is a header:

<?xml version="1.0" encoding="UTF-8"?>
<grammar xmlns="http://www.w3.org/2001/06/grammar" version="1.0" xml:lang="en-US" tag-format="semantics/1.0" root="ROOT">

Here is an example of a simple tag:

 <item>
   <item>eighteen</item>
   <tag>out.dd1="1"; out.dd2="8";</tag>
 </item>

Here is an example with references to tags from other rules:

 <item>
   <ruleref uri="#singleDigit" />
   <tag>out.d5=rules.singleDigit.d;</tag>
 </item>

And here an example of the use of ECMAScript concatenation:

 <tag>out.zip=out.d1+out.d2+out.d3+out.d4+out.d5;</tag>
