Isn't that exactly why iPhone / iOS will ask you to say 'Hey Siri' several times when you activate the feature? I assumed it was tuning the recognition to key on just [approx] that voice.
It's not "secure" in any sense, but it cuts down on false positives and perhaps some very juvenile hacking attempts. Any professional hacker will generate a close-enough voiceprint that you can't use voice recognition inherently (purely passively) as authentication any time soon.
