Abstract
In this paper, we propose a closed loop system to improve the performance
of single-channel speech separation in a speaker independent
scenario. The system is composed of two interconnected blocks: a
separation block and a speaker identiſcation block. The improvement
is accomplished by incorporating the speaker identities found
by the speaker identiſcation block as additional information for the
separation block, which converts the speaker-independent separation
problem to a speaker-dependent one where the speaker codebooks
are known. Simulation results show that the closed loop system enhances
the quality of the separated output signals. To assess the improvements,
the results are reported in terms of PESQ for both target
and masked signals.
