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.

Speech recognition services

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. In some instances, the speech recognition platform engages in a back-and-forth dialog with the user in order to properly fulfill the user's request.

Managing dialogs on a speech recognition platform

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

A language-based system may be configured to interact with a user by understanding natural language of the user and may provide functions and services in response to such natural language. Certain functions and services may be provided by third-party applications that register serviceable intents with the language-based system. A serviceable intent indicates an intent that the third-party application is able to fulfill or service. Upon determining an intent of the user based on natural language interaction with the user, the system identifies one of the third-party applications that has specified a matching serviceable intent and selects that application for use by the user.

Application discovery and selection in language-based systems

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 voice-based system may comprise a local speech interface device and a remote control service. A user may interact with the system using speech to obtain services and perform functions. The system may allow a user to install applications to provide enhanced or customized functionality. Such applications may be installed on either the speech interface device or the control service. The control service receives user speech and determines user intent based on the speech. If an application installed on the control service can respond to the intent, that application is called. Otherwise, the intent is provided to the speech interface device which responds by invoking one of its applications to respond to the intent.
