description	Systems and techniques for low power key phrase detection are disclosed herein. An audio sample may be captured in a power management integrated circuit (PMIC). Here, the PMIC is physically differentthan a sensor circuit of an integrated system and the PMIC has a lower power leakage than the sensor circuit. The integrated system may be awoken upon a trigger. The audio sample may then be transferred to the integrated system to perform key phrase detection (KPD). The integrated system may be put to sleep in response to completion of the KPD. 本文公开了用于低功率关键短语检测的系统和技术。音频样本可在功率管理集成电路(PMIC)中被捕捉。此处，PMIC在物理上不同于集成系统的传感器电路，并且PMIC具有比传感器电路更低的功率泄漏。集成系统可基于触发器来唤醒。音频样本可随后被传送到集成系统以执行关键短语检测(KPD)。集成系统可响应于KPD的完成而被置为睡眠。
