Ok -- I might be stupid.

That being made clear, does it seem to you that Seryoga's {O} sounds are being nasalized?

For instance, the word "champion," coming at around 1:06, as well as the word immediately following.

Here's the clip:

There are few other instances throughout.

Do you agree with my assessment -- do you think he's saying the vowels rather nasally/atypically?

If so -- is this stylistic? Or just a reflection of his Belorusian roots...?
