  • Patent number: 11600291
    Abstract: This disclosure describes techniques for identifying a voice-enabled device from a group of voice-enabled devices to respond to a speech utterance of a user. A speech-processing system may receive an audio signal representing the speech utterance captured in an environment of a voice-enabled device, and identify another voice-enabled device located in the environment. The system may analyze the audio signal using a different natural-language-understanding model for each of the voice-enabled devices to identify an intent for each of the voice-enabled devices to respond to the speech utterance. The system may determine confidence scores that the intents are responsive to the speech utterance, and select the intent with the highest confidence score. The system may use the selected intent to generate a command for the corresponding voice-enabled device to respond to the user.

  • Patent number: 9882975
    Abstract: A method and an apparatus for buffering and obtaining resources as well as a resource buffering system are disclosed. The method includes: obtaining an access popularity value of a resource from a database at intervals of a first preset time, and obtaining load values of cache servers from the database if determining that the access popularity value reaches a preset first threshold; and determining a duplication cache server for duplicating the resource according to the access popularity value and the load values, and notifying the duplication cache server to duplicate the resource from a cache server that stores the resource and buffer the resource. The method overcome the problems in the prior art, namely, the same resource is buffered in only one cache server and the relatively idle cache servers are unable to share loads with busy cache servers. The method improves extensibility and working efficiency of the buffering system.
