Vocalocity Property Defaults

Properties are used to set values that affect platform behavior, such as the recognition process, timeouts, and caching policy. You should specify properties in the top-level VoiceXML document in your application. This section contains the default browser properties the VoiceXML interpreter will use, if you do not provide them in the application.

The VoiceXML specifications group these properties into the following categories:

u Generic speech recognition

u Generic DTMF recognition

u Prompting and collection

u Fetching

u Miscellaneous
