Abstract
Audio information is recorded in an overwriteable circular buffer of a computing device. Construction of a search query is initiated by receiving a user input. The user input includes one or more keywords forming a user-defined portion of the search query. At least a portion of the audio information recorded in the overwriteable circular buffer is processed to obtain one or more additional keywords forming an expanded portion of the search query. The portion of the audio information containing the additional keywords is received and recorded in the overwriteable circular buffer prior to receiving the user input. The search query including the user-defined portion and the expanded portion is supplied to a search engine. A response to the search query is received from the search engine. The response is generated by the search engine based on the user-defined portion and the expanded portion of the search query.
