Officials who apparently thwarted an alleged terror plot against Europe used voiceprinting technology to catch several suspects.
The British Government Communications Headquarters, which snoops on criminal suspects and works with MI6 spies, used voice identification technology to help uncover the plot, AP says. Several of the voices were recorded along the Pakistan-Afghanistan border.
Technological advances have brought audio recording a long way over the past several decades, but, as with so many things, microphone recording is limited by the very technology that has pushed it forward. In this particular case, that limit is the diaphragm that converts sound into electrical signals by measuring vibrations made by incoming sound waves. Because each diaphragm has its own characteristics, all microphones are not created equal; and because the sound waves are converted by these diaphragms, there is always some degree of mechanical interference with the sound.
Google Voice is one of those technical advancements that could change your way of communication. With it, you can sign up for a single phone number that rings every phone you own. Then you can hand out the number to everyone you know.
