Abstract
A low-power voice command detection method uses an audio monitoring device to capture sound. The captured sound is analyzed in steps to determine if it fulfills a number of criteria regarding sound level, voice content and identifiable voice commands. For each step the processing is more complex and power demanding. A threshold between the first and subsequent steps is used to gate further processing. This threshold is dynamically adjusted, based on the outcome of the analysis, to avoid unnecessary processing and increase system performance.
