Speech Recognition is one of the main elements of natural language processing, or computer speech technology. Speech is derived from sounds created by the human articulatory organs, such as the vocal cords and the tongue. Through variable exposure to speech during infancy, a child is able to understand similar-sounding utterances from different people, perhaps due to the phonetic regularities in the syllables they hear. The mental capabilities of the brain helps humans achieve this remarkable capability. So far, we have only been able to reproduce this in computers on a limited basis.

The Challenge of Speech Recognition: Writing systems are ancient, going back as far as the Sumerians of 6,000 years ago. The phonograph, which allowed the analog recording and playback of speech, dates to 1877. Speech recognition had to await the development of computer, however, due to multifarious problems with the recognition of speech.

Several versions of the film exist, with the biggest differences between the original U.S. theatrical release and Ridley Scott's preferred 'Final Cut' of his work, which appeared in 2007. The plot concerns the pursuit of several bioengineered 'replicants' by Deckard, a police officer assigned to eliminate them in the dystopian streets of Los Angeles, 2019; it deals with themes of slavery and what it means to be human.
