A system for enabling end user devices to access third party cloud-based resources. For example, the system may include a first party cloud-based resource for converting sound into a format accessible to the third party cloud-based resource, storing and/or maintaining state information related to the an open communication session between the end user device and the third party cloud-based resources, and converting text-based audio announcements into audio that may be output by the end user device. In some cases, the first party cloud-based resource may transmit user responses together with stored state information to the third party cloud-based resources in a manner that the third part cloud-based resources may treat each interaction with the end user as a separate communication session.

Stateless third party interactions

A voice-controlled device may receive a voice command uttered by a user, where the voice command may request that the voice-controlled device perform an operation. The voice-controlled device and/or one or more remote computing resources may process an audio signal associated with the voice command to determine text corresponding to the voice command. The resulting user utterance may be associated with a unique identifier, which may be provided to a third party and/or third party application that is to provide information responsive to the user request. The information provided by the third party/third party application may be output to the user based at least partly on the unique identifier, without disclosing user data associated with the user.

Associating identifiers with audio signals

Techniques for creating a persistent connection between client devices and one or more remote computing resources, which may form a portion of a network-accessible computing platform. This connection may be considered 'permanent' or 'nearly permanent' to allow the client device to both send data to and receive data from the remote resources at nearly any time. In addition, both the client device and the remote resources may establish virtual channels over this single connection. If no data is exchanged between the client device and the remote computing resources for a threshold amount of time, then the connection may be severed and the client device may attempt to establish a new connection with the remote computing resources.

Load-balanced, persistent connection techniques

A speech-based system includes a local device in a user premises and a remote service that uses the local device to conduct speech dialogs with a user. The local device may also be directed to play audio such as music, audio books, etc. When designating audio for playing by the local device, the remote service may specify that the audio is either background audio or foreground audio. For background audio, the service indicates whether the background audio is mixable. For foreground audio, the service indicates an interrupt behavior. When the local device is playing background audio and receives foreground audio, the background audio is paused, attenuated, or not changed based on the indicated interrupt behavior of the foreground audio and whether the background audio has been designated as being mixable.

Attribute-based audio channel arbitration

A system enables end user devices to receive audio announcements from third party cloud-based resources. For example, the system may include a first party cloud-based resource providing tokens to the third party cloud-based resource in order to prevent the third party cloud-based resource from causing audio announcements to be output by user devices without authorization. In some cases, the tokens may be time based and prevent the third party cloud-based resource from causing audio announcements to be output by user devices after a predefined amount of time. In other examples, the tokens may be use based and prevent the third party cloud-based resource from causing the user device to output more than a predetermined number of audio announcements.

Third party audio announcements

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.

Disclosed are various embodiments for supervising execution of untrusted code. Untrusted code that is to be executed in a computing device is obtained. A virtual machine in the computing device is configured to execute the untrusted code, with one or more resource access restrictions being placed on the untrusted code. Periodic updates are obtained from the virtual machine relating to one or more resources of the computing device that are consumed by the virtual machine. Execution of the untrusted code in the virtual machine is interrupted in response to a value indicated by one or more of the periodic updates.

Supervising execution of untrusted code

In some embodiments, a user device receives a voice signal corresponding to a user utterance. The user device may set a time marker corresponding to a point in time in the voice signal. The voice signal and the time marker may be transmitted to a server device. The server device may perform speech recognition using the voice signal. The server device may determine a time offset corresponding to a difference in time between an end point of the user utterance and a time associated with the time marker. The server device may determine a response to the user utterance. The server device may transmit the time offset and the response to the user device. The user device may use the time offset to determine a user-perceived latency between the end of the user utterance and a beginning of the response.
