 note = {The use of an audio sensor is a direct and useful approach for detecting various contexts related to apnea and sleeping state. In previous studies by the authors, the use of multiple microphones improved the performance of recognizing sleep-related contexts. However, this method had the challenge to use during sleep due to the large size of the device. Therefore, this study developed a small-sized wearable device by combining the use of contact and open-air microphones and evaluated it in sleep setting. A preliminary experiment was conducted to adjust the fixation parameters of the device to the user's body. Then, an in-sleep experiment in a minimum noise environment was held to obtain the long-time sleep data of four participants. Finally, a wearable system consisting of a wearable sensor and a desktop application was proposed to monitor contexts related to apnea and sleeping state., The use of an audio sensor is a direct and useful approach for detecting various contexts related to apnea and sleeping state.
