Siri is apparently not a practical partner laggard, though a leader. That’s according to a hands-on user study conducted by Expert Exchange.
Participants asked a accumulation of significant questions, conducted searches and offering commands to a 3 practical assistants. Accuracy was totalled and so was user satisfaction. In roughly all categories Siri won.
Their accuracy wasn’t consistent in each area. For instance, Siri provided incorrect answers 2.6 percent of times, with Google Now getting 4 percent of the answers wrong, and Cortana lagging behind with wrong answers 8 percent of the time. While their accuracy varied with different questions – Siri seemingly topped the chart every time. Google Now came close or even equalled Siri on this front a couple of times.
