A request to identify a person is received from a user. For example the user may say 'Find me the name of a person who sent me an email regarding Project X last week.' The request is to identify the person in order to establish an electronic communication session with the identified person. The request is parsed to identify one or more filtering criteria. One or more electronic record stores are determined based on the one or more filtering criteria. For example, specific devices on a network are identified. The one or more electronic record stores are searched using the one or more filtering criteria to create a filtered list of persons. The filtered list of persons is displayed on a first communication device in a simplified user interface. The simplified user interface dramatically reduces the time and steps necessary to identify the person and establish the communication session.

A method of engineering media path selection is described. Addresses and media paths are selected using a media path selection policy. Additionally, a candidate address list may be considered. Using the media path selection policy, devices may select the first hop egress router and a remote default router for transferring data.

Recognizing a user's speech is a computationally demanding task. If a user calls a destination server, little may be known about the user or the user's speech profile. The user's source system (device and/or server) may have an extensive profile of the user. As provided herein, a source device may provide translated text and/or speech attributes to a destination server. As a benefit, the recognition algorithm may be well tuned to the user and provide the recognized content to the destination. Additionally, the destination may provide domain attributes to allow the source recognition engine to better recognize the spoken content.

A method, system and voice browser execute voice applications to perform a voice-based function. A document is retrieved and parsed to create a parse tree. Script code is created from the parse tree, thereby consuming part of the parse tree to create a reduced parse tree. The reduced parse tree is stored in a cache for subsequent execution to perform the voice-based function.

A speech recognizer performs speech recognition on a spoken name supplied by a user, producing a list of possible matches and corresponding confidence scores, by comparing a packetized voice stream of a spoken name to a plurality of stored phonemes that represent users' text names. If the top scoring match for a spoken name does not correctly identify the spoken name or if the spoken name's confidence score is below a first threshold, the user name is flagged to the system administrator as having a potential speech recognition problem. The results of the speech recognition are used to suggest names whose spelling may need to be adjusted to resolve the speech recognition problem. During production, a low threshold for rejecting speech recognition results can be adjusted downwards for names that produced low scores during testing. Heuristics are presented for re-testing only a subset of names when the set of names is changed.

An indication of a change in a right to use a service or feature is received. For example, this can be based on an administrator granting access to a previously installed service or feature. In response, a notification is sent to a user of the change of the right to use the service or feature. The notification requests the user to provide a credential to approve the change of the right to use the service or feature. For example, a link may be provided in an email or text message that the user can click on to provide a password/user name. The credential is received and verified. In response to validating the credential, access is allowed according to the change of the right to use the service or feature. The user then has access to the service/feature without the administrator having to know the user's credential.

An application compositor enables the creation a sequence of SIP and HTTP servlets that comprises a converged multi-protocol application. Applications are constructed based on rules that declaratively specify a multi-protocol sequence of servlets and the transitions between the servlets, minimizing programmer effort. The application compositor works with a servlet container within an application server to determine the sequence of servlets to be executed by the servlet container when running the application, and is called by the servlet container to perform transitions between servlets.

A method and apparatus for incorporating a third user into an instant message (IM) session. In one embodiment, an IM server receives a first IM from a first user directed toward a second user. The IM server makes a determination that the second user is not available to respond to the first IM. In response to the determination, the IM server identifies a third user to whom the first IM is to be forwarded, and automatically forwards the first IM to the third user. In another embodiment, the IM server receives a transfer request from the second user to transfer the IM session from the second user to the third user. The IM server automatically determines a subset portion of a plurality of IMs communicated between the first user and the second user, and provides the transfer request and the subset portion to the third user.

A method and apparatus for accessing messages from a message server. Messages are stored on the message server in their current format without transcoding. When a client opens a session with the message server, a data transfer rate is determined for the client. In response to a message retrieve request, the bit rate of the message is compared to the data transfer rate, and if less than the data transfer rate, the message is downloaded to the user terminal without transcoding. If the bit rate is greater than the data transfer rate, then the message is transcoded to a lower bit rate according to a codec supported by the user. The codec may be selected from a set of codecs supported by the user terminal. The user is provided with the capability to override the system selected codec, for example, to pick a codec for secure encoding or encryption.

A method and apparatus for increasing channel capacity in an Internet-based voice messaging system. Voice messages are stored in client mailboxes in the voice compression format they are received in a call answering session. During a message pickup session, the voice compression format of the retrieved message is compared to the voice compression formats or codecs supported by the user's terminal. If the voice compression format is not the same, re-negotiation is attempted, and if unsuccessful the voice message is transcoded prior to playback. If the voice compression format is the same, then the voice message is played back without transcoding. The voice message server also includes a voice prompt module which stores voice prompts in all the voice compression formats or codecs supported by the voice message server. The voice prompts are selected according to the supported voice compression format or codec and played back without the need for any transcoding.

A method, apparatus and data structure for managing data in a memory device. The memory device is divided into two volumes. The first volume is intended for storing relatively static data, i.e. data which does not change or is not rewritten frequently. The second volume is intended for storing dynamic data, i.e. data which is changed or rewritten frequently. Each of the volumes is divided into a number of blocks, for example erase blocks, with each block being divided into sectors. In the dynamic volume, each of the erase blocks has one sector allocated for storing metadata, and the remaining sectors in the erase block are available for storing data, other than metadata. In the static volume, each of erase blocks can store more than one sector of metadata, in addition to data other than metadata. The metadata may be stored in consecutive sectors in the erase blocks. According to another aspect, the data structure is suitable for flash disk memory devices and flash disk memory devices used for multimedia applications.

A system and method for speech recognition includes a speaker-independent set of stored word representations derived from speech of many users deemed to be typical speakers and for use by all users, and may further include speaker-dependent sets of stored word representations specific to each user. The speaker-dependent sets may be used to store custom commands, so that a user may replace default commands to customize and simplify use of the system. Utterances from a user which match stored words in either set according to the ordering rules are reported as words.
