Abstract

An apparatus for providing a speech probability estimation is provided. The apparatus includes a first speech probability estimator for estimating speech probability information indicating a first probability on whether a sound field of a scene includes speech or on whether the sound field of the scene does not include speech. Moreover, the apparatus includes an output interface for outputting the speech probability estimation depending on the speech probability information. The first speech probability estimator is configured to estimate the first speech probability information based on at least spatial information about the sound field or spatial information on the scene.
