Cisco VVB VoiceXML Elements: Reference Table

This appendix contains the VoiceXML elements used by Cisco VVB, and summarizes the elements and their attributes, and their corresponding parent and children elements in the VoiceXML 2.0/2.1.

Note

If an unsupported element is used in a VoiceXML document, an error event is generated.

<assign> element

Attributes

name, expr

Parents

block, catch, error, filled, help, if, noinput, nomatch

Children

-

<audio> element

Attributes

src, fetchtimeout, fetchhint, maxage, maxstale, expr

Parents

block, catch, choice, emphasis, error, field, filled, help, if, initial, menu, noinput, nomatch, object, p, paragraph, prosody, record, s, sentence, subdialog, transfer, voice

Children

audio, break, emphasis, enumerate, mark, p, paragraph, phoneme, prosody, s, say-as, sentence, value, voice, #pcdata

Notes

Audio file formats supported are audio/basic and audio/wav.

A uniform resource identifier (URI) in the <audio src> element can point to a block of speech markup data, but such support is dependent on, and conditional to the vendor's decision of where the <audio src> element can point.

The following codecs are supported for each file format:

  • G711A

  • G711U

  • G729

The default codec is G711U.

Notes

The attribute weight is ignored.

Cisco supports XML and regular expression (regex) grammars:

  • Cisco supports Nuance extensions for XML grammar.

  • Cisco supports regex grammar for DTMF input.

The attribute xml: base declares the base URI from which relative URIs in the <grammar> element are resolved. This base declaration has precedence over the <vxml> base URI declaration. If a local declaration is omitted, the value is inherited down the document hierarchy.
