Sample results on LRS3+WHAM!

We generated synthetic mixtures containing 2 speakers plus noise by combining the LRS3 [1] and WHAM! [2] datasets. The Signal-to-Noise Ratio is uniformly sampled within the range [-5, 5] dB for clean speech and [-6, 3] dB for the noise, following the mixing procedure originally described in WHAM!.
The following table shows the results for 10 randomly selected examples from the test set.
