Artificial Intelligence and Wernicke's and Broca's Area

Speech production in Artificial Intelligence is an issue that scientists and engineers have come across for a great period of time. Like any form of technology, we must observe nature to imitate it for the future of Artificial Intelligence. Our brain contains two areas that contribute to our fluent speech in a respective language. These areas are called Wernicke's area and Broca's areawhich are both located on the left hemisphere. Wernicke's area stores information required for speech content, arranging the words of a learned vocabulary into meaningful speech according to rules of grammar, and Broca's area is instructed by Wernicke's area to move the tongue, lips, and other speech muscles in harmony.

Manipulating a machine posed as a person to speak a language and behave in a social way must contain a system that emulates Broca's area and Wernicke's area. This system would be the one which would output the articulate sets of words for a fluent speech. Our frontal left hemisphere(holder of Wernicke's and Broca's area) contains about five billion cells which explains our capacity for a diverse set of words for speech. A compartmentalization of sets of words in forms of digital storage in an intelligent machine could act as Wernicke's area. Different categories of words such as adjectives, nouns, and verbs are to be organized in storage and located through an algorithm which would facilitate response. our brain works exactly like this but it is hard to grasp its multitude of responses that are the result of billions of intricately organized neurons. It would take years to produce a storage system and sets of responses to millions of different sensory inputs just as it takes years for a child to develop speech recognition and response.

Broca's area would be emulated b a high quality speaker system and a sensitive coordination of lips. After sensory input has been processed by the machine to produce a response, an output of words through a speaker to emulate the harmony of a tongue, throat and lips would occur. Lips along with a set of fake teeth would be installed on the machine.

A system like the human body contains many different underlying systems which work in coherence to produce what we are. Imitating Wernicke's and Broca's area plays no role on solving the problem of how an intelligent machine could learn through experience because survival is not on its mind. Humans learn to keep reproduction, survival, and pleasure afloat which is something a robot cannot do.
