Step-size parameter adaptation of multi-channel semi-blind ICA with piecewise linear model for barge-in-able robot audition

Abstract: Abstract-This paper describes a step-size parameter adaptation technique of multi-channel semi-blind independent component analysis (MCSB-ICA) for a "barge-in-able" robot audition system. By "barge-in", we mean that the user can speak simultaneously when the robot is speaking. We focused on MCSB-ICA to achieve such an audition system because it can separate a user's and a robot's speech under reverberant environments. The problem with MCSB-ICA for robot audition is the slow speed of convergence in estimating a… Show more

“…The frame interval parameter, d, was 2, and the default filter taps for echo cancellation and dereverberation were the same, M bd = M ec = 20. The parameters for adaptive step-size control were set to Takeda et al's settings [9]. There were 15 iterations when the filter was estimated, which is not a huge number of iterations.…”
