    Everyone's voice is a unique mixture of sound frequencies. Yelling, stress, and so forth modify the mixtures. But the basic structure is still in there. It's like taking a fingerprint on Silly Putty then stretching and twisting it.

    So bottom line, vocal analysts will be able to take vocal samples from the various 911 calls. They'll be able to give testimony along the lines of DNA analysis ... XX% chance of a match to GZ or TM.

    I saw one clip from a local news team who hired such an analyst. Of course he was not testifying. I don't trust my memory to report exactly what was said. IIRC it was not beneficial to GZ.
