Abstract
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.
