I have downloaded a video from the internet.

The video part plays correctly.

The music (instrumental) part plays correctly.

The file is not bad. It does play.

Only problem is the human voice is corrupted.

I myself tried to correct the file and to some extent I am successful.

What did I do?

I extracted the sound track from the file (using winff in ubuntu). Then opened the sound file in audacity and increased the pitch of the frequency (40 hz to 70 hz) and the sound is somewhat corrected. Then remixed the sound with the video and got the video some what corrected.
