Okuno, "Blind separation and dereverberation of speech mixtures by joint optimization," accepted for publication in IEEE Transactions on Audio, Speech, and Language Processing, Jan. 2010. This paper is now available on IEEE Xplore located at http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=5428853&tag=1. [Computation time] The algorithm was implemented in MATLAB and run on a Linux workstation equipped with a 2.4GHz processor. The computation times are listed below. I used three different configurations, and so the computation times for those three are described in the file. ---------------------------------------------------------------------- x_array10cm_test12 5.53 sec x_array10cm_test13 5.67 sec x_array10cm_test14 5.34 sec x_array10cm_test15 5.86 sec x_array10cm_test16 5.65 sec x_array10cm_test17 5.61 sec x_array10cm_test18 5.19 sec x_array10cm_test23 5.32 sec x_array10cm_test24 5.74 sec x_array10cm_test25 5.79 sec x_array10cm_test26 5.84 sec x_array10cm_test27 6.09 sec x_array10cm_test28 6.19 sec x_array10cm_test34 5.55 sec x_array10cm_test35 5.72 sec x_array10cm_test36 5.40 sec x_array10cm_test37 5.19 sec x_array10cm_test38 5.67 sec x_array10cm_test45 6.52 sec x_array10cm_test46 5.97 sec x_array10cm_test47 5.74 sec x_array10cm_test48 7.82 sec x_array10cm_test56 5.65 sec x_array10cm_test57 5.67 sec x_array10cm_test58 6.14 sec x_array10cm_test67 5.73 sec x_array10cm_test68 5.80 sec x_array10cm_test78 5.65 sec x_array2cm_test12 5.34 sec x_array2cm_test13 5.47 sec x_array2cm_test14 5.23 sec x_array2cm_test15 5.26 sec x_array2cm_test16 5.14 sec x_array2cm_test17 5.11 sec x_array2cm_test18 5.11 sec x_array2cm_test23 5.28 sec x_array2cm_test24 5.67 sec x_array2cm_test25 5.25 sec x_array2cm_test26 5.36 sec x_array2cm_test27 5.44 sec x_array2cm_test28 5.56 sec x_array2cm_test34 5.04 sec x_array2cm_test35 5.36 sec x_array2cm_test36 5.16 sec x_array2cm_test37 5.12 sec x_array2cm_test38 5.31 sec x_array2cm_test45 6.12 sec x_array2cm_test46 5.73 sec x_array2cm_test47 5.67 sec x_array2cm_test48 7.67 sec x_array2cm_test56 5.51 sec x_array2cm_test57 5.59 sec x_array2cm_test58 5.84 sec x_array2cm_test67 5.34 sec x_array2cm_test68 5.75 sec x_array2cm_test78 5.44 sec x_array6cm_test12 5.41 sec x_array6cm_test13 5.46 sec x_array6cm_test14 5.53 sec x_array6cm_test15 5.44 sec x_array6cm_test16 5.32 sec x_array6cm_test17 5.36 sec x_array6cm_test18 5.48 sec x_array6cm_test23 5.30 sec x_array6cm_test24 5.56 sec x_array6cm_test25 5.41 sec x_array6cm_test26 5.54 sec x_array6cm_test27 5.45 sec x_array6cm_test28 6.01 sec x_array6cm_test34 5.32 sec x_array6cm_test35 5.71 sec x_array6cm_test36 5.22 sec x_array6cm_test37 5.08 sec x_array6cm_test38 5.58 sec x_array6cm_test45 6.09 sec x_array6cm_test46 6.31 sec x_array6cm_test47 5.95 sec x_array6cm_test48 8.06 sec x_array6cm_test56 5.59 sec x_array6cm_test57 5.64 sec x_array6cm_test58 5.97 sec x_array6cm_test67 5.61 sec x_array6cm_test68 6.04 sec x_array6cm_test78 5.81 sec Avg 5.66 sec
