Mm - hmm.
Actually I started with  using the VAD to estimate the noise and then I found that it works  it doesn't work for Finnish and Spanish because the VAD endpoints are not good to estimate the noise because it cuts into the speech sometimes , so I end up overestimating the noise and getting a worse result. So it works only for Italian by u for  using a VAD to estimate noise.
Mm - hmm.
It works for Italian because the VAD was trained on Italian.
