The voice sounded like 'der Anzug ist tod' which is what I wrote since I beleive it!
Yes, you're right. I am a German native and I hear "Der Anzug is trot."
ist->is is usual in spoken language, but "trot" does not exist. (What exists is "der Trott", but that does not matter here.)
"Der Anzug ist rot." and "Der Anzug is rot." are both ok; the standard is a mixture of both. But is this Audio "ist" and "rot" are connected, what they should not be.
