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.

Abstract translation: 低功率语音指令检测方法使用音频监视装置来捕获声音。 捕获的声音被分阶段地分析以确定它是否满足关于声级，语音内容和可识别的语音命令的一些标准。 对于每个步骤，处理更加复杂和功率要求很高。 第一步和后续步骤之间的阈值用于进一步处理。 根据分析结果动态调整此阈值，避免不必要的处理并提高系统性能。
