System and methods for processing audio signals are disclosed. In one implementation, a system may include a wearable apparatus including an image sensor to capture images from an environment of a user; an audio sensor to capture an audio signal from the environment of the user; and at least one processor. The processor may be programmed to receive the audio signal captured by the audio sensor; identify at least one segment including speech in the audio signal; receive an image including a representation of a code; analyze the code to determine whether the code is associated with the user and/or the wearable apparatus; and after determining that the code is associated with the user and/or the wearable apparatus, transmit at least one segment of the audio signal, at least one image of the plurality of images, and/or other information to a computing platform.
