Passively monitoring a user's breathing with a device can include identifying breathing modes of the user's breathing and responsive to detecting a trigger mode based on the identifying, generating an instruction adapted to the trigger mode. The instruction can be conveyed to the user via the device. The monitoring can include determining phases of the user's breathing with the device. Determining the phases can include receiving acoustic signals generated by an acoustic sensor in response to a user's breathing and generating acoustic data comprising features extracted from the acoustic signals. Phases of the user's breathing can be determined by classifying the acoustic data using a machine learning model trained based on signal processing of motion signals generated by a motion sensor in response to human breathing motions. Though trained using signal processing of motion signals, the machine learning model is trained to classify acoustic data.

Aspects of the present disclosure provide methods, apparatuses, and systems for dynamically adjusting a breathing entrainment based on whether a user is stressing or relaxing. According to an aspect, a first target breathing period is selected, and a guiding stimulus configured to alter a current breathing period of the user towards the first target breathing period over an interval of time is output. One or more relaxation biometrics are measured and analyzed to determine whether the user is stressing or relaxing. Based on whether the user is relaxing or stressing, at least one of the guided stimulus and the first target breathing period are adjusted, where the first target breathing period is adjusted to a second target breathing period different from the first target breathing period. By making adjustments based on whether a user is relaxing or stressing, the breathing entrainment is more effective and comfortable for users.
