Abstract: Configurable core domains of a speech processing system are described. A core domain output data format for a given command is originally configured with default content portions. When a user indicates additional content should be output for the command, the speech processing system creates a new output data format for the core domain. The new output data format is user specific and includes both default content portions as well as user preferred content portions.

Abstract: This disclosure proposes systems and methods for entity resolution using speech recognition data. The system can receive audio data representing an utterance and perform automatic speech recognition (ASR) processing on the audio data to generate at least a first ASR data and a second ASR data. The system can perform natural language understanding (NLU) processing on the first ASR data to determine intent data and an indication of an entity. The system can determine a first portion of the first ASR data that corresponds to the indication of the entity. The system can determine a second portion of the second ASR data that corresponds to the indication of the entity without performing NLU on the second ASR data. The system can perform entity resolution (ER) on the second portion to identify a first entity.

Abstract: Techniques for implementing multiple wakeword detectors on a single device are described. A digital signal processor (DSP) of the device may initially include an untrained wakeword detection component. The wakeword detection component of the DSP may be trained by engaging a user to speak particular utterances. Once a companion application is configured to implement a wakeword detection component, the companion application's wakeword detection component may be trained specific to the user of the device. Once the companion application's wakeword detection component is trained, the DSP wakeword detection component may be deactivated or its accuracy adjusted.

Abstract: Cohorts may be created on storage nodes in an object-redundant storage system that uses replication and/or a redundant encoding technique. In a cohort with N nodes, M data elements (replicas or shards) of an object are stored to M of the nodes that are randomly (or otherwise) selected from the N nodes. Metadata for locating other data elements for an object in the cohort may be stored with one or more of the data elements in the cohort. To retrieve an object from a cohort, a subset of the nodes may be queried; the subset may be randomly or otherwise selected. If enough data elements are retrieved for the object from the queried nodes, the object is provided to the requester. Otherwise, additional data elements may be retrieved according to the metadata returned with a data element or by querying additional nodes.

Abstract: Speech-controlled searching and browsing for content using speech-controlled devices, or other input-limited devices, is described. A user may audibly indicate to a speech-controlled device whether the user wants to search or browse for content, along with a topic of the content/results to be retrieved. A server, located remotely from the speech-controlled device determines an appropriate endpoint device for displaying results of the requested search or browse. The server also determines an appropriate content source for the requested content, and sends a request for the content to the content source. The server receives search or browse results from the content source and forwards them to the determined endpoint device.

Abstract: Disclosed are various embodiments for transmitting an application download from a donor to a recipient or recipients. The donor defines parameters for transferring the application download, including payment distribution between the donor and recipient, delivery method of a notification of the application download to the recipient, identification of the recipient or recipients, a deadline for downloading the application, a maximum number of recipients, and other data relevant to transmitting an application download. Parameters are encoded in an identifier that may be decoded by the recipient's client device or that may be imaged and sent to a server providing the application download service. Various embodiments display the encoded identifier to the recipient via electronic displays or printed mediums. The recipient scans or captures an image of the displayed encoded identifier using a client device.

Abstract: A system that implements a scalable data storage service may maintain tables in a non-relational data store on behalf of clients. The system may provide a Web services interface through which service requests are received, and an API usable to request that a table be created, deleted, or described; that an item be stored, retrieved, deleted, or its attributes modified; or that a table be queried (or scanned) with filtered items and/or their attributes returned. An asynchronous workflow may be invoked to create or delete a table. Items stored in tables may be partitioned and indexed using a simple or composite primary key. The system may not impose pre-defined limits on table size, and may employ a flexible schema. The service may provide a best-effort or committed throughput model. The system may automatically scale and/or re-partition tables in response to detecting workload changes, node failures, or other conditions or anomalies.

Abstract: Embodiments may include a consistency measurement component that utilizes memory-efficient sets (e.g., Bloom filters) assigned to different time periods for tracking when different write operations are performed on replicated data objects within a distributed data store. The consistency measurement component may evaluate whether read operations directed to the distributed data store are inconsistent. To do so, the consistency measurement component may determine, for a given read operation, the age of the value read from a given replicated data object (e.g., by evaluating a “last-modified” timestamp). The consistency measurement component may identify a memory-efficient set that includes the key of that replicated data object in order to determine when the replicated data object was last written to. If the age of the value read is older than the time at which the replicated data object was last written to, the consistency measurement component may determine that the read operation was inconsistent.
