<option>

Specifies an option within an input field. An option list is represented by a set of <option> elements within a <field> element. Note that the <option> element does not only contain PCDATA. 

With Voice Platform, you can also specify <grammar> elements and embedded text-to-speech elements within your option list. This means you can specify <grammar> elements to override any grammar automatically generated by the option list.

Attributes

This section describes the attributes you can set for this element.

Name	Data type	Default
accept	(exact | approximate)	exact
dtmf	CDATA	optional
value	CDATA	optional

accept

The accept attribute specifies the default grammar for each <option> element. If you set this attribute to exact (default), the text that appears within the <option> element specifies the exact phrase to be recognized. If you set this attribute to approximate, then the text that appears within the <option> element specifies an approximate recognition phrase. For example, in response to the prompt "American Heart Association," subphrases such as "Heart Association" or "American Heart" would be recognized.
