The < menu > element presents a menu of choices to the user and transitions to another dialog based on user input.
<menu id="String" scope="dialog" | "document" dtmf="true" | "false" accept="exact" | "approximate"> child elements </menu>
id | The id attribute defines the name of the form. If specified, it can be referenced within the same document or from another document. For example, <form id=“hello”> can be referenced as <goto next=“#hello”/>. This attribute is optional. |
scope | The scope attribute defines the scope of the form’s grammar. This attribute is optional and defaults to dialog. * dialog – the form’s grammars are only active within the form. * document – the form’s grammars are active throughout the document. If this is an application root document, then the form’s grammars are active throughout the application. |
dtmf | The dtmf attribute enables DTMF input for all menu choices. This attribute is optional and defaults to false. * true – the interpreter assigns a DTMF sequence “1”, “2”, “3”… to the choices in order for all menu choices that do not explicitly define a DTMF sequence. * false – the interpreter does not implicitly assign DTMF sequences. |
accept | The accept attribute specifies the default grammar for each <choice> element. This attribute is optional and defaults to exact. * exact – the text of the <choice> element that defines the exact phrase to be recognized. * approximate – the text of the <choice> element that defines an approximate recognition. |
phrase | The phrase attribute is a subset of the words in the phrase expression that can be matched. For example, “Hello world” can be matched with “Hello world”, “Hello”, or “World”. |
