  • Publication number: 20250131940
    Abstract: A data-driven audio codec system that involves producing multiple compressed streams comprising encoded information (e.g., codeword indices) at different time scales (time intervals or frequency). This may allow for separation of different properties of speech, such as content and aspects of style (prosody), into the different compressed streams without explicitly enforcing it, i.e., in an unsupervised manner. Speech audio is encoded to produce a plurality of encoded streams comprising encoded information for the speech audio at different time scales. The plurality of encoded streams are decoded to generate output audio.

  • Publication number: 20250087215
    Abstract: Presented herein are techniques in which a device detecting a phrase spoken in an online collaboration session between a plurality of users, the phrase being spoken by a first user to one or more second users. The device determines that the phrase indicates an issue with a quality of user experience of the online collaboration session, labels a log of metrics associated with the online collaboration session with a time stamp corresponding to a time when the phrase was spoken; and performs one or more actions to improve the user experience based on detecting the phrase.

  • Publication number: 20240161765
    Abstract: In one example embodiment, speech signals are received from a user during a communication session. The received speech signals contain noise including speech of other individuals. The received speech signals are transformed by a machine learning model to produce transformed speech signals corresponding to the received speech signals with a reduced amount of the noise. The machine learning model is trained with speech of the user satisfying a noise threshold and collected during one or more communication sessions.

  • Patent number: 9710581
    Abstract: Using verification IP (VIP), the related design IP (DIP) can be integrated into a system on a chip (SOC) without requiring the IP component. Using a normalized framework, a software module can be integrated into the VIP software stack enabling the customized management of the VIP beyond the standard specification defined behaviors. Then, the modified software stack can be used to manage both behaviors defined by the specification and the design specific behaviors. The VIP can then be used in place of the DIP for SOC development.

  • Patent number: 9280627
    Abstract: A system and method that implement an object-oriented model for requirements of a hardware design in order to verify the design. The object-oriented model abstractly captures the design topology, capability, control, and status of the design. An object-oriented model or definition of a hardware design is based on one or more specifications or standards implemented with the design. With the object-oriented model, a system and method for storing and displaying data captured during a test run is implemented. Graphical displays are defined to show run information for abstract objects of the design. Predefined graphical displays may be altered to accommodate the features of the object-oriented model and new graphical displays may be defined for objects in the model.

  • Patent number: 9208282
    Abstract: In a system and method that simulates a design including a third party IP component, a driver for the IP component is compiled and executed in a workstation implementing the simulation platform for the design. The source code for the driver is modified to allow the simulation to reroute certain functions that would cause the simulator to hang until an event occurs that would unlock the simulation. The rerouting includes storing instruction location, state information, and any other context information needed to restore a paused function. The saved information is stored in a stack that is traversed upon detection of the event.

  • Patent number: 9183331
    Abstract: A system and method that tests an IP component of a hardware design generates an abstract model of the IP component based on knowledge of the design and one or more protocols implemented with the IP component. A generic driver and associated interfaces are additionally generated or selected to test the IP component within the hardware design.

  • Publication number: 20140173541
    Abstract: Method and apparatus for verifying debugging aspects of integrated circuit (IC) designs. In one aspect, an IP provider(s) can use the same process that isolated IP defect(s) to demonstrate to the customer (whether an IC designer or an IP consumer such as a smartphone manufacturer) that the debugging was successful, and that errors in operation will not recur. In another aspect, the invention provides a facility that enables the IP provider to demonstrate to an IP consumer that a repaired IP component will work under a sufficiently broad set of circumstances, without that demonstration revealing the provider's proprietary IP to the consumer.

  • Publication number: 20140173539
    Abstract: Method and apparatus for debugging aspects of integrated circuit (IC) designs employ techniques by which defective intellectual property (IP) in those IC designs can be exercised, and defects identified, without disturbing the IP itself, but at the same time isolating the source of the defect(s) to the responsible IP provider(s). The IP provider then can debug the IP. In one aspect, the techniques give the IP provider(s) specific information about the nature of the defect, facilitating the provider's efforts to debug the IP.
