TY - CHAP U1 - Konferenzveröffentlichung A1 - Freudenberger, Jürgen A1 - Grimm, Simon T1 - Frequency-dependent speaker detection using a microphone array T2 - Fortschritte der Akustik : DAGA 2016, Aachen : 14.-17. März 2016 : 42. Jahrestagung für Akustik, Tagungsband N2 - In this paper we propose a method to determine the active speaker for each time-frequency point in the noisy signals of a microphone array. This detection is based on a statistical model where the speech signals as well as noise signals are assumed to be multivariate Gaussian random variables in the Fourier domain. Based on this model we derive a maximum-likelihood detector for the active speaker. The decision is based on the a posteriori signal to noise ratio (SNR) of a speaker dependent max-SNR beamformer.
