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.
