  • Patent number: 9552816
    Abstract: A speech-based system includes an audio device in a user premises and a network-based service that supports use of the audio device by multiple applications. The audio device may be directed to play audio content such as music, audio books, etc. The audio device may also be directed to interact with a user through speech. The network-based service monitors event messages received from the audio device to determine which of the multiple applications currently has speech focus. When receiving speech from a user, the service first offers the corresponding meaning to the application, if any, that currently has primary speech focus. If there is no application that currently has primary speech focus, or if the application having primary speech focus is not able to respond to the meaning, the service then offers the user meaning to the application that currently has secondary speech focus.

  • Patent number: 9424840
    Abstract: A speech recognition platform configured to receive an audio signal that includes speech from a user and perform automatic speech recognition (ASR) on the audio signal to identify ASR results. The platform may identify: (i) a domain of a voice command within the speech based on the ASR results and based on context information associated with the speech or the user, and (ii) an intent of the voice command. In response to identifying the intent, the platform may perform a corresponding action, such as streaming audio to the device, setting a reminder for the user, purchasing an item on behalf of the user, making a reservation for the user or launching an application for the user. The speech recognition platform, in combination with the device, may therefore facilitate efficient interactions between the user and a voice-controlled device.

  • Patent number: 9334972
    Abstract: A check valve includes a valve body, a pair of stoppers, a hinge pin, and one or more flappers. The valve body includes an inlet end, an outlet end, and an inner surface that defines a flow passage between the inlet end and the outlet end. The inner surface further defines a valve seat adjacent the inlet end. The stoppers are integrally formed on the valve body inner surface, and each has a first end and a second end. The hinge pin is disposed within each hinge pin opening and extends across the flow passage. The flappers are disposed within the flow passage and are rotationally mounted on the hinge pin. Each of the one or more flappers is rotatable between a closed position, in which the flapper engages the valve seat, and a full-open position, in which the flapper engages the pair of stoppers.

  • Patent number: 9293138
    Abstract: Network-based services may be provided to a user through the user of a speech-based user device located within a user environment. The speech-based user device may accept speech commands from a user and may also interact with the user by means of generated speech. Operating state of the speech-based user device may be provided to the network-based service and stored by the service. Applications that provide services through the speech-based interface may request and obtain the stored state information.

  • Patent number: 9240187
    Abstract: Features are disclosed for generating markers for elements or other portions of an audio presentation so that a speech processing system may determine which portion of the audio presentation a user utterance refers to. For example, an utterance may include a pronoun with no explicit antecedent. The marker may be used to associate the utterance with the corresponding content portion for processing. The markers can be provided to a client device with a text-to-speech (“TTS”) presentation. The markers may then be provided to a speech processing system along with a user utterance captured by the client device. The speech processing system, which may include automatic speech recognition (“ASR”) modules and/or natural language understanding (“NLU”) modules, can generate hints based on the marker. The hints can be provided to the ASR and/or NLU modules in order to aid in processing the meaning or intent of a user utterance.
