Abstract: Responsive to an incoming telephone call, a session server consults pre-stored caller preferences to generate a source file of caller-specific audio content, then conducts an interactive playback session audibly presenting the content to the caller. Each call's source file may include an internally stored history record documenting events that occur during playback, such as caller utterances, identity of audio content presented, voice prompts presented to the caller, errors, and time stamps of various playback events. In response to certain caller utterances or completion of the source file's presentation, the session server may reference the history record for guidance in creating an appropriate follow-up source file containing appropriate supplementary audio content. Use may also be made of history records for purposes such as increasing the functionality of interactive user playback, providing billing records, aiding debugging, and preserving data that is useful for marketing purposes.

Abstract: One embodiment of the present invention provides a system for generating speech output from a text string. During operation, the system first receives the text string and then examines the text string to locate one or more substrings within the text string that are found in a speech library. Next, the system looks up speech files associated with the one or more substrings in the speech library. The system then concatenates these speech files to produce a speech output for a user.

Abstract: A system and method for enabling the use of temporary data in an XForms application without requiring the data to be included in the application's instance data. An XForms author includes an extension element in an XForms markup document. The extension element describes element and attributes of desired temporary instance data. The temporary data can be read and written as normal XForms instance data. The temporary data may or may not be serialized, depending on whether exposure to an external data consumer is or is not desired.
