<option>

An option list is represented by a set of <option> elements contained in a <field> element. Each <option> element contains PCDATA that is used to generate a speech grammar.

Attributes

dtmf The DTMF sequence for this option. It is equivalent to a simple DTMF <grammar>, and DTMF properties apply to recognition of the sequence.
value The string to assign to the field's form item variable when a user selects this option, whether by speech or DTMF. The default assignment is the CDATA content of the <option> element, with leading and trailing white space removed. If this does not exist, then the DTMF sequence is used instead.
accept (defaults to "exact") When set to "exact", the text of the option element defines the exact phrase to be recognized. When set to "approximate", the text of the option element defines an approximate recognition phrase.
