Abstract
A wearable device includes various sensors including a microphone, heart rate monitor, pressure sensor, and so forth. The user can set the device to acquire audio data of their speech. For example, if the pressure sensor indicates the device is being worn and the user's heart rate exceeds a threshold value, audio data may be acquired. Onboard the device the audio data is processed in various ways such as detecting whether the audio data includes speech, applying a beamforming algorithm, compressing and encrypting the audio, and so forth. The audio data may be processed onboard the device, sent to another device, or a combination thereof for processing to determine sentiment data indicative of perceived emotional content of the speech. A user interface provides the user with information based on the sensor data, sentiment data, and so forth.
