LOW POWER INTEGRATED CIRCUIT TO ANALYZE A DIGITIZED AUDIO STREAM
First Claim
1. A method for processing audio information, comprising:
- receiving, by a computing device, an audio stream;
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 the digitized audio stream in a memory in the computing device, 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;
transmitting, by the computing device, the stored digitized audio stream to a server for processing; and
rendering, by the computing device, a response received from the server based on the processed audio stream.

Abstract
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.
