  It becomes a bit worse once the background music sets in, but still is 
usable. Feel free to try any other video. I think, it works with any 
video in English.

I think that for "Hollywood"-style movies you will always have a crisp 
sound of the speech. They want the viewers to listen effortlessly - 
background music is typical, "true" noise is rare.

Maybe try with this video:

As soon as they are up in the air you have the engine sound overlaying 
the speech, and still the transcription is quite good. It sometimes 
mistakes the flapping of the engine as "applause" and misses a word or a 
sentence, but still very good.
