Abstract: The invention provides users of either a unified messaging mailbox or simple plain text storage mailbox, with media and device sensitive methods and apparatus to convert messages from one medium to another (when necessary) taking into account the type of target device (for example, cell phone, PDA, pager, etc.), being used to access a stored message Additionally, the invention provides methods and apparatus for determining target device type and for summarizing message content based on target device type.

Abstract: The invention provides the user of a unified messaging mailbox with efficient, intelligent, media and device sensitive methods and apparatus to access and process (e.g., read, listen, forward, and search) messages. The invention introduces media conversion capabilities to selectively treat multimedia messages and message attachments so that they can be efficiently handled by mobile devices like PDAs (Personal Digital Assistants), pagers, or phone devices (with or without a text display feature). Furthermore, the invention introduces message content analysis capabilities that will recognize linguistic relationships between messages regardless of the media type. The invention also describes the ability to present these linguistic relationships along with the standard messaging relationships (Message arrival time, subject, sender, etc.). Still further, the invention introduces a message referencing option that allows simpler message selection from certain devices.

Abstract: A system and a method for quantitatively measuring voice transmission quality within a voice-over-data-network such as a telephony-enabled LAN utilize speech recognition to measure the quality of voice transmission. A first aspect of the invention involves determining the suitability of the LAN for voice communications. A voice sample is selected by a first terminal and is transmitted to a second terminal on the LAN a number of times. The first terminal introduces an incrementally larger quantity of noise into each transmission of the voice packet. The second terminal performs speech recognition for each successively received voice sample and determines the accuracy for each speech recognition session. The amount of noise which drops the speech recognition accuracy below a threshold level provides a measure of the suitability of the LAN for voice communications. During normal operation of the LAN, speech recognition accuracy tests are performed between various endpoints to monitor voice transmission quality.

Abstract: A method and system for supporting a real-time communication on an integrated packet-based network involve accumulating information about the communication, referred to as signature data, while the communication is being setup and/or is in progress and storing the signature data in a database that is openly accessible to any applications that are connected to the network. Once signature data regarding an active real-time communication is accumulated, portions of the signature data may be utilized to further process the active real-time communication. Providing an openly accessible communication profile that is accumulated while the communication is in progress allows applications to provide a higher level of service by tailoring actions to the profile of the specific communication.

Abstract: A system and method for organizing and accessing multi-media messages from a displayless interface. According to one embodiment, voice recognition techniques are used to allow the user to identify and create a hierarchical organization for stored messages.

Abstract: The invention provides the user of a unified messaging mailbox with efficient, intelligent, media and device sensitive methods and apparatus for automatically summarizing messages stored in a unified multimedia mailbox. Additionally, the invention provides methods and apparatus that convert non-text messages to text to facilitate summarization utilizing predefined keywords and/or lists of keywords, where each list of keywords is linked to one of a message subject and a message sender. Further, the invention provides for the prioritization of messages via the application of filtering techniques.

Abstract: A method and system for personalized multimedia messaging include multiple communication mode interfaces which enable the system to communicate with multiple types of communication devices. Caller profiles are configured for preselected callers such that each caller profile includes at least one caller identifier representative of data patterns in incoming. calls received over the communication modes. The caller profiles are selectively configured to include personalized messages intended for a subset of the preselected callers and can also include caller identity verification data. A caller identification subsystem monitors the communication modes for incoming calls which include the data patterns. Upon detecting one of the data patterns, a processor accesses a corresponding caller profile and determines if the caller profile includes a personalized message.

Abstract: A method and system for enabling call notification for a user of a telephonic device, such as a telephone, computer or video conference system, include forming a notification message having content-specific information relating to the subject matter of interest to the calling party. Preferably, the notification message also includes caller identification. In one embodiment, the application of the method is restricted to call-waiting circumstances, but this is not critical. The content-specific information is acquired using automated processes, such as interactive voice recognition. Voice responses are converted to a proper text format for presentation on a display of the target telephonic device. The display of the notification message presents the content-specific information in a nonintrusive manner. The called party is thereby able to form an informed decision as to whether to answer the incoming call, interrupt an ongoing call, or forward the call and/or the notification message to a mailbox.

Abstract: The present invention relates to a call forwarding system for forwarding telephone calls to a target telephone not having a direct dial number. The call forwarding system includes an intelligent forwarding unit for storing a forwarding direct dial number and the extension number for accessing the target telephone and for connecting the received forwarded call to the target telephone, a voice response unit including a DTMF decoder for receiving the forwarded telephone call and for decoding the extension number of the target telephone. A call connecting unit directly connects the in-coming telephone call to the target telephone.

Abstract: A method and an apparatus for providing visual aid to a presenter involve converting the spoken words of a presenter into an electronic text format, electronically comparing the converted spoken words to electronically stored reference text to find text string matches, utilizing the text string matches between the converted spoken words and the reference text to determine a current location of the presentation with respect to the reference text, and delivering upcoming portions of the reference text to the presenter as needed to enable a continuous presentation by the presenter. A preferred presentation support system is incorporated into a portable personal computer that includes a speech recognition subsystem. The speech recognition subsystems allows a presentation to be tracked in real-time so that presentation support material can be automatically displayed to the presenter in synchronization with the in-progress presentation.
