Abstract: System and techniques for visually impaired augmented reality are described herein. An utterance may be received from a user. The utterance may be classified to produce a filter. The user's environment may be classified based on the filter to produce an environmental event. An audible interpretation of the environmental event may be rendered.

Abstract: Systems and techniques for lower 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 different than 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.
