The elusive recognition of voices

  

Voice recognition is one of those technologies that are wrought with peaks of anticipation followed by valleys of disappointments. The quest for finding a practical human voice recognizer has been an ongoing challenge ever since the first attempts at human-machine interface.

The latest consumer oriented human-machine interface is Siri, an intelligent personal assistant and knowledge navigator application for Apple's iOS. Dag Kittlaus, the co-founder and former CEO of Siri sold the technology to Apple. Apple claims that the software adapts to the user's individual preferences over time and personalizes results, and performs rudimentary tasks such as recommending nearby restaurants, or getting directions.
