FIELD: physics.
SUBSTANCE: device for providing a speech probability estimation comprises the first speech probability estimation means for estimating speech probability information indicating the first probability as to whether the scene sound field contains speech or whether the scene sound field does not contain speech. Additionally, the device comprises an output interface for deriving the speech probability estimation depending on speech probability information. The first speech probability estimation means is configured to estimate information of the first speech probability based on, at least, spatial information about the sound field or spatial information about the scene.
EFFECT: increasing the accuracy of detecting useful and parasitic sounds.
