A voice browser dialog enabler for multimodal dialog uses a multimodal markup document with fields have markup-based forms associated with each field and defining fragments. A voice browser driver resides on a communication device and provides the fragments and identifiers that identify the fragments. A voice browser implementation resides on a remote voice server and receives the fragments from the driver and downloads a plurality of speech grammars. Input speech is matched against those speech grammars associated with the corresponding identifiers received in a recognition request from the voice browser driver.

A multimodal browser for rendering a multimodal document on an end system defining a host can include a visual browser component for rendering visual content, if any, of the multimodal document, and a voice browser component for rendering voice-based content, if any, of the multimodal document. The voice browser component can determine which of a plurality of speech processing configuration is used by the host in rendering the voice-based content. The determination can be based upon the resources of the host running the application. The determination also can be based upon a processing instruction contained in the application.

A computer system in the form of a voice command platform includes a voice browser and voice-based applications. The voice browser has global-level grammar elements and the voice applications have application-level grammar and grammar elements. A programming feature is provided by which developers of the voice applications can programmably weigh or weight global-level grammar elements relative to the application-level grammar or grammar elements. As a consequence of the weighting, a speech recognition engine for the voice browser is more likely to accurately recognize voice input from a user. The weighting can be applied on the application as a whole, or at any given state in the application. Also, the weighting can be made to the global level grammar elements as a group, or on an individual basis.

A network comprises a number of speech-enabled sites maintaining a number of voice pages. A central server on the network executes a voice browser which provides users with access to the sites using voice-activated hyperlinks. The server also maintains and brokers information associated with the users based on spoken dialogs between the users and the sites. In response to a user accessing a given ASR site, information about that user is provided by the server for use by that ASR site. The information is used by the ASR site to optimize a spoken dialog between the user and the ASR site by reducing the amount of information the user is required to provide during the dialog. Information about the user can thereby be shared between separate speech enabled sites, in a manner which is transparent to the user, in order to expedite the user's interaction with those sites.

The present invention relates to a system for acquiring information from sources on a network, such as the Internet. A voice browsing system maintains a database containing a list of information sources, such as web sites, connected to a network. Each of the information sources is assigned a rank number which is listed in the database along with the record for the information source. In response to a speech command received from a user, a network interface system accesses the information source with the highest rank number in order to retrieve information requested by the user.

A technique for synchronizing a visual browser and a voice browser. A visual browser is used to navigate through visual content, such as WML pages. During the navigation, the visual browser creates a historical record of events that have occurred during the navigation. The voice browser uses this historical record to navigate the content in the same manner as occurred on the visual browser, thereby synchronizing to a state equivalent to that of the visual browser. The creation of the historical record may be performed by using a script to trap events, where the script contains code that records the trapped events. The synchronization technique may be used with a multi-modal application that permits the mode of input/output (I/O) to be changed between visual and voice browsers. When the mode is changed from visual to voice, the record of events captured by the visual browser is provided to the voice browser, thereby allowing the I/O mode to change seamlessly from visual to voice. Likewise, the voice browser captures events which may be provided to the visual browser when the I/O mode is changed from voice to visual.

A system authenticates an electronic transaction between a first user-operated device and a computer. The computer is configured to conduct electronic transactions. The system includes a voice browser and a session correlator. The voice browser is configured to receive and process user-spoken information from a second user-operated device, where the voice browser is programmed to compare a user-spoken transaction identifier to a computer generated transaction identifier, and to compare a user-spoken verification identifier to a voice print of the user. The session correlator is coupled to the voice browser and is configured to transmit an authentication message to the computer if the user-spoken transaction identifier matches the computer transaction identifier, and if the user-spoken verification identifier matches the voice print.

The grammar of the speech input to a voice service system is normally specified by the voice service system. However, this can produce problems in respect of idioms, such as dates, which are expressed different ways by different users. To facilitate the handling of idioms, a user is permitted to specify their own idiom grammar which is then used by the voice service system to interpret idioms in speech input from that user. Typically, the normal grammar of speech input is specified by grammar tags used to mark up a voice page script interpreted by a voice page browser; in this case, it will generally be the voice browser that is responsible for employing the user-specified idiom grammar to interpret the corresponding idiom in the speech input by the user. The user-specified grammar can be pre-specified directly to the voice browser by the user or fetched by the browser from a remote location on the fly.

An interactive media system for an IP Multimedia Subsystem (IMS) architecture includes a media resource function processor (MRFP) and a media resource function controller (MRFC). The MRFP includes media resources, such as automatic speech recognition (ASR) engines and text-to-speech (TTS) engines, and a voice browser. A caller places a call to a telephone number to reach an interactive media service, and the MRFC establishes a real-time packet media session between the media gateway and the MRFP. The voice browser queries a location server to determine the location of an interactive application associated with the called telephone number and then queries an application server corresponding to the location to obtain the interactive application as a voice extensible markup language (VXML) document. The browser interprets the VXML document and responsively invokes the media resources, via the MRFC, to provide the interactive media service to the caller.

A response is provided to the user request on the basis of the file of converted information.

A method for providing a voice application includes executing control flow logic modeling a dialog flow with a user via a voice browser. The control flow logic produces a disambiguation requirement. A disambiguation module is initiated and a set of at least two candidates and partitioning criteria is sent from the control flow logic to the module. Attributes of the candidates are analyzed to determine a partitioning score for each attribute indicative of ability to distinguish between candidates based on the partitioning criteria. The attributes are sorted based on the partitioning scores. The user is queried based on a top-sorted attribute and results of the query are used to reduce the set of candidates. The steps of analyzing, sorting, and querying are repeated until the set of candidates is reduced to a single candidate. The single candidate is returned to the control flow logic for continued execution.

A content interpolating web proxy server is configured in a computer network for processing retrieved web content so as to place it in a format suitable for presentation on a particular client device such as, e.g., a computer, personal digital assistant (PDA), wireless telephone or voice browser-equipped device. The server processes a client request generated by a client device to determine a particular client type associated with the client device, retrieves web content identified in the client request, retrieves one or more augmentation files associated with the web content and the particular client type, and alters the retrieved web content in accordance with the one or more augmentation files. The altered web content is then delivered to the client device. The one or more augmentation files may be co-located with the web content at a site remote from the proxy server, such that the content owner need not own, maintain or otherwise control the proxy server.
