Abstract: Systems and methods for generating command indications, via a computing device, based on audio data including a keyword are described. The computing device receives and processes audio data to determine whether the audio data includes a keyword. The keyword may be a device user identifier, such as an individual's name. Once a keyword is detecting, audio data surrounding the keyword is processed to determine a command contained within the surrounding data, and the command is conveyed to the computing device's user either audibly or visually. Alternatively, a location of the device is determined, a command is determined based on the device's location, and the command is conveyed to a user of the device either audibly or visually.

Abstract: Disclosed are various embodiments of a search engine for software applications. An application and first application metadata are received, and the application is scanned to identify second application metadata. The first and second application metadata are added to a search index corresponding to a plurality of applications offered via an application marketplace system. A search query is received, and a search of the search index is performed for the search query. One or more search results are generated from the search.
