Merging the ability of speech to relay text allows the user to control the machine or the information with the use

of advanced tracking tools digital device just by speaking, replacing the use acts as a fundamental pillar of modern day Speech of traditional input methods like using keystrokes, Recognition. Essentially, Speech Recognition (SR) button clicks, or screen taps. words and phrases spoken and converts them into a machine readable format, paving the way for a is a combination of Linguistics, Computer Science, Electrical Engineering, and Statistics, allowing for recognition and translation of spoken language into text using smart technologies and devices. Speech Recognition technology can be better understood correlating it with how our human body recognizes speech. Science has proven than humans detect speech using our ears. People identify the meaning of the words using the left side of their brain, which is more analytical, and decode the associated emotions and expressions using the right side of their brain, which is more holistic and creative. Speech Recognition uses a similar

task break up to reproduce a similar set of functions to analyze sounds and speech. Prevalent speech recognition solutions make use of machine-based recognition, allowing them to recognize speech based on pre registered words and sentences. 2 susheel ext@uniphore.com Source: http://www.doksinet THE RELEVANCE OF ARTIFICIAL INTELLIGENCE AND MACHINE LEARNING IN SPEECH RECOGNITION Overview of various application of Speech Recognition technology is also playing a dominant role in restoring short Speech Recognition solutions allow consumers of Introduction in brief - AI (Artificial Intelligence) and ML (Machine Learning) various brands to interact with the brand, replacing in part the need for the traditional customer service agent.

In a world besieged by the relentless advance of digital technology, terms like Artificial intelligence (AI), Machine Learning (ML), and Deep Learning (DL) have

become quite common. Often, these terms are used interchangeably, though there is a clear demarcation between them. The one common denominator that binds all such terms like Ml and AI is that they help evolve a machine-intelligence environment, simplifying human-machine communication. While AI and ML have their own dedicated spheres of use, AI is best understood as a branch of computer science that allows for building smart machines capable of behaving “intelligently” in the right environment. ML, on the other hand, is the science of getting these machines or computers to act smartly without being programmed excessively.

Artificial Intelligence (AI): ArtificiaI Intelligence is all about making machines intelligent using advanced computer intelligence. The core driver of AI based technology is to be able to create a machine or a computer that can act just as intelligently as a human mind does. At its core, AI is based on various disciplines like Computer Science, On the other hand, if a program is developed using AI, it will not only answer the specific question but also answer related general questions but understanding the questions intelligently. AI-based Speech Recognition tools understand not only languages spoken by their users, but also can track emotions, accents, and behavior patterns using Biology, Psychology, Linguistics, Mathematics, and speech modulation driven by AI. Engineering. Machine Learning (ML): Machine Learning can be best understood as a subset

of AI whereby the smart AI capable machine uses large data sets to “learn” on its own. ML-based systems make use of these large data sets, apply training algorithms, and develop “knowledge” from those data sets. ML eventually allows programs to recognize patterns and make appropriate predictions based on the same. Many ML-based Speech Recognition systems, for example, offer sales analysis by gauging and correlating a customer’s mood with his or her likelihood of being receptive to a sales offer. 4 susheel ext@uniphore.com Source: http://www.doksinet THE RELEVANCE OF ARTIFICIAL INTELLIGENCE AND MACHINE LEARNING IN SPEECH RECOGNITION Configuration of business rules: AI and ML allow Speech Recognition applications to customize as per their core business rules.
