Claim:
1. A method, comprising: receiving, by a computing device, an audio stream; continuously monitoring, by a low power integrated circuit of the computing device, the audio stream; digitizing, by the low power integrated circuit, the audio stream; storing, by the low power integrated circuit, the digitized audio stream in a memory, wherein storing the digitized audio stream comprises replacing a prior digitized audio stream stored in the memory with the digitized audio stream; analyzing, by the low power integrated circuit, the stored digitized audio stream for recognition of a keyword; upon recognition of the keyword within the stored digitized audio stream, inducing, by the low power integrated circuit, a processor of the computing device to enter an increased power usage state; retrieving, by the processor, the stored digitized audio stream from the memory; converting the stored digitized audio stream to a text stream using the processor; and prompting the computing device to perform one or more actions based on the text stream.
