Does Voice Password Offer Unique Advantages for BIometrics?

Biometrics such as fingerprint recognition, retina recognition, voiceprint seem like appealing alternatives to the time-tested password. But one big drawback--if biometric data is compromised, as Slate says, "You Can't Change Your Fingerprints". 

But is voice different? Because a voiceprint is inherently sort of like a two-factor approach: a thing you know (your passphrase) and a thing you have (your voice). If your voiceprint is compromised, then you can just use your same voice, with a new passphrase, to create a new voiceprint. Like creating a new password.

This website seems to support my reasoning.

(Obviously no security technology is perfect. Speaking out loud has privacy implications that swiping a finger does not. Supposedly impersonation or pre-recording is not a problem, though.)
