Definition
AI is the study of the abilities for computers to perform tasks, which currently
are better done by humans. AI has an interdisciplinary field where computer science
intersects with philosophy, psychology, engineering and other fields. Humans make
decisions based upon experience and intention. The essence of AI in the integration
of computer to mimic this learning process is known as Artificial Intelligence
Integration
When you dial the telephone number of a big company, you are likely
to hear the sonorous voice of a cultured lady who responds to your call with great
courtesy saying "welcome to company X. Please give me the extension number
you want" .You pronounces the extension number, your name, and the name of
the person you want to contact. If the called person accepts the call, the connection
is given quickly. This is artificial intelligence where an automatic call-handling
system is used without employing any telephone operator. The
Technology
Artificial intelligence
(AI) involves two basic ideas. First, it involves studying the thought processes
of human beings. Second, it deals with representing those processes via machines
(like computers, robots, etc).AI is behaviour of a machine, which, if performed
by a human being, would be called intelligence. It makes machines smarter and
more useful, and is less expensive than natural intelligence.
Natural language processing (NLP) refers to artificial intelligence methods of
communicating with a computer in a natural language like English. The main objective
of a NLP program is to understand input and initiate action.The
input words are scanned and matched against internally stored known words. Identification
of a keyword causes some action to be taken. In this way, one can communicate
with the computer in one's language. No special commands or computer language
are required. There is no need to enter programs in a special language for creating
software. Voice XML takes speech recognition
even further. Instead of talking to your computer, you're essentially talking
to a web site, and you're doing this over the phone.OK, you say, well, what exactly
is speech recognition? Simply put, it is the process of converting spoken input
to text. Speech recognition is thus sometimes referred to as speech-to-text.Speech
recognition allows you to provide input to an application with your voice. Just
like clicking with your mouse, typing on your keyboard, or pressing a key on the
phone keypad provides input to an application; speech recognition allows you to
provide input by talking. In the desktop world, you need a microphone to be able
to do this. In the Voice XML world, all you need is a telephone. The
speech recognition process is performed by a software component known as the speech
recognition engine. The primary function of the speech recognition engine is to
process spoken input and translate it into text that an application understands.
The application can then do one of two things:The
application can interpret the result of the recognition as a command. In this
case , the application is a command and control application. If an application
handles the recognized text simply as text, then it is considered a dictation
application.
The user speaks to the computer through a microphone, which
in turn, identifies the meaning of the words and sends it to NLP device for further
processing. Once recognized, the words can be used in a variety of applications
like display, robotics, commands to computers, and dictation.
