Description

Hi,Thanks to the good job!
When I running in the speech mode with two same audio sampled at 16KHz, the MOS values of many results are around 4.4-4.6, and it did not reach the maximum value of 5.0. However, the NSIM score and similarity of all audio segments are 1.0. Is this a normal phenomenon?
I got these results using the SVR model you provided:"lattice_tcditugenmeetpackhref_ls2_nl60_lr12_bs2048_learn.005_ep2400_train1_7_raw.tflite"
