So I have a basic question regarding Siri. I'm stuck on an Iphone 4 for now so can't experiment myself. All the commercials show people speaking to Siri in a normal tone of voice and at a normal speed. But the few people I've seen using Siri have been talking in a slower, methodical way. Obviously trying to be very clear. I know this question is way outdated, just thought I'd ask. Hoping to upgrade to a 5S when it shows up in Sept.
