Emotion recognition from speech signals is an important but challenging component of Human-Computer Interaction (HCI). In the literature of speech emotion recognition (SER), many techniques have been utilized to extract emotions from signals, including many well-established speech analysis and classification techniques. Deep Learning techniques have been recently proposed as an alternative to traditional techniques in SER. This paper presents an overview of Deep Learning techniques and discusses some recent literature where these methods are utilized for speech-based emotion recognition. The review covers databases used, emotions extracted, contributions made toward speech emotion recognition and limitations related to it. A Multilayer Perceptron (MLP) deep learning model has been described to recognize voice gender. The data set have 3,168 recorded samples of male and female voices. The samples are produced by using acoustic analysis. An MLP deep learning algorithm has been applied to detect gender specific traits.

With advancement in artificial intelligence (AI), Deep learning models are used to imitate the actions of human beings. These activities of personage are controlled by their brain and similar to that, machines are capable of data processing, decision making, speech recognition and language translations just like human beings. One of the applications of deep learning includes Autonomous Vehicles design i.e., driver less cars. To implement this, we need an automatic traffic sign recognition (TSR) model. These models are designed with the use of convolutional neural networks (CNN). The main task of this model is to extract the various features of the different traffic sign images and classify according to unique categories. This paper includes a comprehensive review of various models that can be used for classifying traffic signs. Researchers have applied various CNN models to predict the class of traffic sign and these are proven to be better than machine learning algorithms. CNN works as a feed forward neural network which has been stimulated from animal visual cortex.

A chatbot is emerged as an effective tool to address the user queries in automated, most appropriate and accurate way. Depending upon the complexity of the subject domain, researchers are employing variety of soft-computing techniques to make the chatbot user friendly. It is observed that chatbots have flooded the globe with wide range of services including ordering foods, suggesting products, advising for insurance policies, providing customer support, giving financial assistance, schedule meetings etc. However, public administration-based services wherein chatbot intervention influence the most, is not explored yet. This project discuses about artificial intelligence based chatbots including their applications, challenges, architecture and models. It also talks about evolution of chatbots starting from Turing Test and Rule-based chatbots to advanced Artificial Intelligence based Chatbots. AI-Chatbots are providing much kind of services, which this project outlines into two main aspects including customer based services and public administration based services. The purpose of this survey is to understand and explore the possibility of customer & public administration services based chatbot. The survey demonstrates that there exists an immense potential in the AI assisted chatbot system for providing customer services and providing better governance in public administration services. And even among the AI assisted chatbots conversational interfaces have been a trending topic in recent years. As of the last decade, CIs have emerged with the aim of simplifying human-machine interactions and found a wide use case in the market. For example, Siri and Google Assistant are some of the most well-known CIs developed by the tech giants Apple and Google. The digital landscape has evolved from web, to mobile apps, to recently CIs. Nowadays, CIs, in particular chatbots and voicebots, are becoming increasingly common. Whether navigating the web or messaging on a phone, it is likely that CIs have been confronted offering the user help. However, CIs have not managed to reach a large-scale use. Furthermore, the reasons regarding the challenges faced by CIs as well as their usability are not greatly explored. Here in our project we combine the features of an AI chatbot with the conversational interface to provide services to people in public and customer based services.

Today's undergraduates are expected to have 21st-century skills as part of learning and developing critical thinking abilities. Indeed, the “National Education Policy 2020” seeks to establish an educational system founded on the rich diversity of India's linguistic, cultural, and creative traditions. Refusing to recognize English as an Indian language in the National Education Policy is a sly attempt to impose Hindi. Local languages, particularly tribal ones, are being lost, and this paper expresses worry about their dwindling space. The English and English-aware elites blame the marginalization of other Indian languages as naive. This research paper explains that the value of language cannot be overstated when discussing education. Because of the diversity of Indian languages, the NEP encourages multilingualism and bilingual education while emphasizing the need to improve proficiency in Indian languages. Regarding acquiring a job, "English" is still up for debate regarding its cultural values and ethos. However, the policy's instructions for language usage must be examined in the language classroom. The students of undergraduate Engineering degrees need to be taught about Indian culture and the arts to create a strong sense of cultural identity and an appreciation for art, as they are more prone to migration for higher studies or for better career opportunities (software) but not as a compulsion. Ancient India's language and education were caste-based. The English educational system helped people escape constrained knowledge systems. This attribute improved the country's appeal when the British left. Many middle-class Indian parents believe that sending their children to an English-medium school will help them in the employment market. English is crucial to our global commercial and social competitiveness.
