Bridge To Siri: You're Taking Shotgun This Flight
When giving the Enterprise a command, Starfleet members neither repeat themselves nor push a button to do it. Today's voice-activated technology requires users first engage the voice controls, letting it know a command is about to be given as opposed to an always-on voice recognition system. As smart as Apple's Siri might be, she can't do that. And, Star Trek seems to have a much more nuanced voice recognition system, capable of interpreting any number of linguistic cues and taking the appropriate actions. Google did announce its attempt to make a more "natural," voice-activated means of search, called "Conversational Search," which uses the phrase "Okay Google" to engage the capabilities, like Siri (pictured). And, speaking of sassy Siri, voice-activated future tech never seems to really talk back; Starfleet crewmembers aren't sitting around having full-on conversations with a computer. Perhaps future folks have no need for computer-validated responses beyond notifications.
