Abstract: Features are disclosed for detecting words in audio using environmental information and/or contextual information in addition to acoustic features associated with the words to be detected. A detection model can be generated and used to determine whether a particular word, such as a keyword or “wake word,” has been uttered. The detection model can operate on features derived from an audio signal, contextual information associated with generation of the audio signal, and the like. In some embodiments, the detection model can be customized for particular users or groups of users based usage patterns associated with the users.

Abstract: Methods and apparatus for a client account versioning metadata manager for cloud computing environments are disclosed. A system includes a plurality of resources, a plurality of service managers coordinating respective multitenant network-accessible services, and a metadata manager. The metadata manager receives a multi-service account state view request. The metadata manager generates a representation of an administrative state of a client account indicated by the request with respect a plurality of services accessible by the client account, as of a time indicated in the request. The administrative state with respect to a particular service comprises an indication of an assignment to the client account of resources participating in implementation of the particular service.

Abstract: An interactive system may be implemented in part by an audio device located within a user environment, which may accept speech commands from a user and may also interact with the user by means of generated speech. In order to improve performance of the interactive system, a user may use a separate device, such as a personal computer or mobile device, to access a graphical user interface that lists details of historical speech interactions. The graphical user interface may be configured to allow the user to provide feedback and/or corrections regarding the details of specific interactions.

Abstract: A system for controlling multiple devices using automatic speech recognition (ASR) even when the devices may not be capable of performing ASR themselves. A device such as a media player, appliance, or the like may be recognized by a network. The configured controls for the device (such as a remote control or other mechanism) are incorporated into a device control registry which catalogs device command controls. Individual ASR grammars are constructed for the devices so speech commands for those devices may be processed by an ASR device. The ASR device may then process those speech commands and convert them into the appropriate inputs for the controlled device. The inputs may then be sent to the controlled device, resulting in ASR control for non-ASR devices.

Abstract translation: 即使设备可能无法执行ASR本身，也可以使用自动语音识别（ASR）来控制多个设备的系统。 诸如媒体播放器，设备等的设备可被网络识别。 设备的配置控件（如远程控制或其他机制）被合并到设备控制注册表中，该设备控制注册表编制设备命令控件。 为设备构建单独的ASR语法，因此这些设备的语音命令可能由ASR设备进行处理。 然后，ASR设备可以处理那些语音命令，并将它们转换为受控设备的适当输入。 然后可以将输入发送到受控设备，导致非ASR设备的ASR控制。
