Abstract: A system can receive an input indicating a user condition. The system can also receive an internal audio stream from an in-ear microphone and an external audio stream from an external microphone of a head worn system. The system can determine a respiration rate of a user based on the internal audio stream, the external audio stream, and the input indicating the user condition. In some implementations, the respiration rate may be determined from a respiration signal in the internal audio stream and/or the external audio stream. The respiration signal may measure breathing of the user. In some implementations, the system can invoke a machine learning model to determine the respiration signal from the internal audio stream and/or the external audio stream based on the user condition.

Abstract: A wearable electronic device includes a housing, and an electrode carrier attached to the housing and having a nonplanar surface. The wearable electronic device includes a set of electrodes, including electrodes positioned at different locations on the nonplanar surface. The wearable electronic device includes a sensor circuit and a switching circuit. The switching circuit is operable to electrically connect a number of different subsets of one or more electrodes in the set of electrodes to the sensor circuit.
