1. An apparatus for providing a speech probability estimation, comprising: a first speech probability estimator for estimating speech probability information indicating a first probability on whether a sound field of a scene comprises speech or on whether the sound field of the scene does not comprise speech, wherein the first speech probability estimator is configured to estimate the speech probability information based on at least spatial information about the sound field or spatial information on the scene, and a second speech probability estimator for estimating the speech probability estimation indicating a second probability on whether the sound field comprises speech or on whether the sound field does not comprise speech, wherein the second speech probability estimator is configured to estimate the speech probability estimation based on the speech probability information estimated by the first speech probability estimator, and based on one or more acoustic sensor signals, which depend on the sound field, and an output interface for outputting the speech probability estimation, wherein at least one of the first speech probability estimator and the second speech probability estimator and the output interface is implemented using a hardware apparatus or a computer or a combination of a hardware apparatus and a computer.
