Failed to recognize Audio

I'm using kali-linux (v)5.18.0-kali5-amd64 and i followed all of the instruction you gave. I tried to test it using the mozilla.wav provided but i didn't get the required output. Instead i got the following message:

When i try using the microphone, I'm receiving tones of samples with zero value error
