Abstract (en)
Device (400) and method for determining if sound is artificial. A hardware input interface (440) obtains (S510) a signal corresponding to sound in an environment, and at least one hardware processor (410) calculates (S520, S530), by from the signal at least one of a descriptor related to loudness and a descriptor related to silence and determines (S540) that the sound is artificial in case a variance of the descriptor related to loudness is below a first threshold value or in case the descriptor related to silence is below a second threshold value.
