Abstract(in English) | This paper reviews several techniques of blind source separation (BSS) used for speech and acoustic signals. These techniques can be classified into two main groups in terms of the type of processing, i.e., frequency-domain independent component analysis (FDICA) and time-domain independent component analysis (TDICA). First, conventional BSS methods based on FDICA and TDICA are briefly reviewed and their drawbacks are discussed. In particular, the trade-off problem between the number of subbands and independence among narrow-band signals in FDICA is explained in detail with the extensive results of speech-separation experiments. Next, we introduce a multistage ICA method proposed in our recent works by emphasizing the effectiveness regarding the signal-separation performances under a reverberant condition. |
