Low power integrated circuit to analyze a digitized audio stream

A computing device for processing audio information, comprising:

• a low power integrated circuit;
• a memory coupled to the low power integrated circuit;
• a processor coupled to the low power integrated circuit and the memory;
• wherein the low power integrated circuit is configured to:
• monitor and digitize an audio stream received by the computing device, the digitized audio stream including a keyword and additional audio;
• store the digitized audio stream in the memory, wherein storing the digitized audio stream comprises replacing a prior digitized audio stream stored in the memory with the digitized audio stream;
• analyze the stored digitized audio stream to recognize the keyword;
• upon recognition of the keyword in the stored digitized audio stream, induce the processor of the computing device to enter an increased power usage state and to obtain at least the additional audio of the stored digitized audio stream from the memory;
• and
• wherein the processor is configured to:
• obtain at least the additional audio of the stored digitized audio stream from the memory;
• transmit at least the additional audio of the stored digitized audio stream to a server for determining one or more actions based on at least the additional audio of the stored digitized audio stream;
• and
• render a response received by the computing device from a server, wherein the response is based on analysis of at least the additional audio of the digitized audio stream.
