Speech signals are inherently nonstationary; however, for short-enough time segments, speech signal can be considered to be stationary. 2. Nonstationarity in speech arises mainly due to amplitude modulation. The ﬁrst property allows the use of the DFT for transforming the mixture data in the spectral domain, whereas the second property allows for the 1 Convolutive Blind Source Separation B(w) 31 P(w) output input Separation System Permutation Resolver Frequency Domain Separation System Fig. 4.

Audio Speech Language Processing, vol. 15, no. 5, pp. 1511–1520, July 2007. jp Abstract. This chapter explains the frequency-domain approach to the blind source separation of acoustic signals mixed in a real room environment. With the application of short-time Fourier transforms, convolutive mixtures in the time domain can be approximated as multiple instantaneous mixtures in the frequency domain. So, separation is performed in each frequency bin with a simple instantaneous separation matrix. We employ complex-valued independent component analysis (ICA) to calculate the separation matrix.
