Description |
This element is used to associate meaning with a rule-expansion inside a grammar. It does not affect what utterances are matched by a given rule-expansion, but associates names or ECMAScript actions so the VoiceXML application can access the results of a recognition. The element will probably change as the Semantic Interpretation for Speech Recognition Specification matures. Note that this element replaces the tag attribute defined in the earlier version of VoiceXML 2.0. |
