Answer 1

The SSML specification does not provide a list of values for the "interpret-as" attribute; it is instead left up to the implementation. You may need to consult the documentation for your SSML processor.

On the other hand, the VoiceXML 2.0 specification does mandate a few builtin types for grammars and the "say-as" element. Note that since "say-as" is actually SSML, you normally must prefix the builtin types with the "vxml:" namespace. You'll need to consult the documentation for your VoiceXML browser to determine whether this is the case. The VoiceXML builtins are:

• vxml:boolean
• vxml:date
• vxml:digits
• vxml:currency
• vxml:number <-- This is the droid you are looking for.
• vxml:phone
• vxml:time
