Unable to create dynamic list of phrases for XML grammar

The information in this article applies to:

• Chant SpeechKit 4

Symptoms

Creating a dynamic list of phrases for an XML Grammar with DefineResource results in an E_INVALIDARG (0x80070057) return code.

Cause

Parameter validation for CSRVocabList was in error. Required parameters include CSRVocabList as the resource type, descriptor that matches the rule name in the XML grammar, and vocabulary resource identifier.

VocabID = ChantSR.DefineResource(CSRGrammarVocab, "c:\\myvocab.xml")
ListID = ChantSR.DefineResource(CSRVocabList, "rulelistname", CRFNone, NULL, NULL, 0, VocabID)
ChantSR.AddResource(CSRVocabPhrase, ListID, "Log Call")
ChantSR.AddResource(CSRVocabPhrase, ListID, "Enter Time")
ChantSR.AddResource(CSRVocabPhrase, ListID, "Schedule Meeting")
ChantSR.EnableResource(CSRGrammarVocab, VocabID)
ChantSR.EnableResource(CSRVocabList, ListID)

XML grammar contains a placeholder for the dynamic rule list:

<GRAMMAR LANGID="409">
<RULE NAME="rulelistname" DYNAMIC="TRUE" TOPLEVEL="ACTIVE">
   <P>placeholder</P>
</RULE>
</GRAMMAR>

Status

Fixed in SpeechKit 4 build 4.0.76.0.
