Methods, devices, and systems for processing audio information are disclosed. An exemplary method includes receiving an audio stream. The audio stream may be monitored by a low power integrated circuit. The audio stream may be digitized by the low power integrated circuit. The digitized audio stream may be stored 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. The low power integrated circuit may analyze the stored digitized audio stream for recognition of a keyword. The low power integrated circuit may induce a processor to enter an increased power usage state upon recognition of the keyword within the stored digitized audio stream. The stored digitized audio stream may be transmitted to a server for processing. A response received from the server based on the processed audio stream may be rendered.

Low power integrated circuit to analyze a digitized audio stream

Examples disclose a low power integrated circuit to receive and digitize an audio stream. Further, the examples provide the low power integrated circuit to compare the digitized audio stream to a keyword and store the digitized audio stream in a memory. Additionally, the examples also disclose upon recognition of the keyword in the digitized audio stream, the low power integrated circuit transmits a signal to a processor to increase power and analyze the digitized audio stream.
