AUDIO RECORDING DEVICE FOR PRESENTING AUDIO SPEECH MISSED DUE TO USER NOT PAYING ATTENTION AND METHOD THEREOF

摘要

An audio recording device (100, 150) is provided. The audio recording device is operative to detect that a user (110) is paying attention to speech (121) captured by a microphone (101), record the captured speech to which the user is paying attention, detect that the user has stopped paying attention, and render a representation of the recorded speech starting at a point in time when the user has stopped paying attention. The representation of the recorded speech may either be rendered audibly, or by transcribing the recorded speech into text and displaying the transcribed text (123), or a summary thereof, to the user. The audio recording device is operative to detect that the user is paying attention to the captured speech by acquiring Electroencephalography (EEG) data captured by electrodes (102) which are attached to a body part of the user, calculating a correlation between the acquired EEG data and the captured speech, and determining that the user is paying attention to the captured speech if the calculated correlation is larger than an upper threshold value.
