Abstract: A system for processing voice audio includes a local device and a remote personal health data ecosystem. The local device includes (1) a local speech-to-text transcriber configured to generate voice text based on voice audio spoken by a user; (2) a local NLP configured to extract spoken phrases from the voice text; and (3) an ML classifier configured to classify the voice audio as either personal health or non-personal health voice audio. The remote personal health data ecosystem includes (1) a remote speech-to-text transcriber configured to generate personal health voice text based on the personal health voice audio; (2) a remote NLP configured to extract personal health spoken phrases from the personal health voice text; (3) a text response generator configured to generate a text response based on the personal health spoken phrases; (4) a text-to-speech translator configured to generate a voice response based on the text response.

Abstract: An oral cleaning system for communicating a status of a handheld oral cleaning device (10) to a docking station (100). The handheld oral cleaning device includes a controller (70) configured to generate a unique charging cycle for each of a plurality of different charging states. The docking station (100) is configured to receive the handheld oral cleaning device, and includes a secondary charging induction coil configured to detect the unique charging cycle for each of the plurality of different charging periods. The docking station further includes a visual indicator (120) configured to indicate, based on the detected charging cycle, one of the plurality of different charging states of the handheld oral cleaning device.
