Sometimes I'll be watching a baseball game in my living room with the volume pretty dang loud. The sound of the crowd in the background is almost like a static noise, and then you have the yellers, as well as the commentators speaking clearly, distinctly, and loudly. Then I use Siri to set a timer for something I'm cooking, or to "Call X person on speaker." and it picks up my voice without any hesitation or anything, and gets the words exactly right.

Definitely accurate.
