Why would it be less accurate? I've worked with voice quite a bit at my last job and the codecs and bitrates for voice don't need to be this heavy-duty CD-quality stuff. Your big limitation is going to be those cheesy mics and background noise, wind, etc. Voice compresses nicely. Turns out we humans aren't capable of making such varied sound that it can't compress. Our mouth holes are ancient technology. In practice, I'm in love with Google's voice capabilities. It seems to understand context. Its crazy how accurate it is. I often tease my iphone friends with it. I'm also highly skeptical that an application on a phone can outdo google's massive libraries and server infrastructure. If anything, I'd expect the Apple voice to be worse. Regardless, I can't wait to see this stuff in action. A war for the best voice recognition would be great right now as its been a patent blocked and ignored field for the most part.
