How can I recognize someone's voice from a spectrogram? A puzzler!

You cannot identify the speaker just by looking at the wave or the spectrogram. Speaker recognition is a big topic with quite a bit of controversy and you need specialized stochastic tools for it.
See Mark Liberman's recent post on this: http://languagelog.ldc.upenn.edu/nll/?p=15175.
It seems that voice biometrics have come a long way but I don't see them showing up in open source speech analytic tools any time soon.
