Information system for converting audio Ukrainian-language text into written one based on NLP methods and machine learning
(онлайн, 2022) Tyshchuk Yuriy; Vysotska Victoria; Luchkevych Mykhailo
Speech recognition provides various ways to analyse and process a user's recorded voice. It allows people to control different systems that are using one of the types of speech recognition. Speech-totext conversion is also a type of speech recognition that uses unscripted conversational data for further processing. This system involves several steps to process an audio file using electro-acoustic tools, sound filtering algorithms to find only relevant sounds, electronic datasets for the chosen language, and mathematical models that find appropriate words for a list of phonemes. People whose professions are related to typing large amounts of text using the keyboard can significantly speed up, facilitate the work process and reduce stress using systems that convert Speech-To-Text. In addition, such systems help businesses because remote work is becoming increasingly popular, and companies need tools for translating recorded audio from meetings to text for further analysis and systematization. The work's study object is converting audio in the Ukrainian language into its textual representation using NLP methods and machine learning. The scope of the research is audio file processing algorithms for finding relevant sounds and recognizing phonemes, as well as mathematical models for identifying words using an array of found phonemes. The work aims to design and develop an information system for converting audio in the Ukrainian language into its textual representation. According to the developments and calculations presented in work, namely: analysis of algorithms, areas of application and review of analogue problems in the first stage, the system analysis of the information system in the second stage and analysis and selection of relevant technologies and software development tools in the third stage, the information system for converting audio in the Ukrainian language into its textual representation was implemented in the form of a web application called «Ukrainian Speech-to-text», which is a technology for accurate and easy analysis of Ukrainian-language audio files and their other transcription into text. The application supports uploading files from the file system, recording them using a microphone, and saving the analysed data. The system is ready for use.
Information system of virtual reality tour of the ISN Department at LPNU with elements of full immersion as a platform for an open day
(онлайн, 2022) Kuznyetsov Oleksiy; Vysotska Victoria; Luchkevych Mykhailo
Virtual reality (VR) is an important technology that allows significant progress to be made in under-covered areas. Immersive multimedia, or virtual reality, is a computer-simulated environment that can mimic a physical presence in the real or imagined world. Innovative applications, such as high-tech systems that integrate display technology, modelling technology, network technology, artificial touch technology, and computer graphics technology have made VR a breakthrough in technology. Virtual reality tours are one way to simulate a presence in a city where a person cannot be physically present at the moment. When viewing virtual tours with videos or photos, a person sees only a flat image and cannot interact with it. Thus, the effect of the fact that it is present in that place is lost. Virtual reality, with the result of complete immersion, eliminates these disadvantages almost completely and allows you to interact with objects located in the virtuality of the scene with the natural movements of your body. In addition, in a short period, with her help, she can visit many places without leaving home, which in real life cannot be done because you need to get to certain areas, which takes time. The research's objective is to conduct an interactive virtual reality tour of the ISN Department of LPNU. The research subject is the means and methods of designing and developing information systems for the virtual reality tour of the ISN Department of LPNU. The practical significance of the obtained results is the implemented information system of the interactive tour of the ISN Department of LPNU. The scientific novelty of the obtained results is the information system of virtual reality, which is designed for a tour of the ISN Department of LPNU with elements of complete immersion as a platform for an open day.

(онлайн, 2022) Hirnyak Oleg
Sentiment analysis is a computational branch of research into people's thoughts, moods,emotions, and attitudes. This fascinating problem is becoming increasingly important in society. The emergence and rapid development of sentiment analysis is associated with the popu arity of social media, discussions on forums, blogs, etc. Considering that this data is full of diverse judgments, moods, and ideas about the world, user content has become the subject of research by a wide range of scientists. There is a need for automatic sentiment analysis, whereas the amount of data is extremely large. Sentiment analysis offers many complex research tasks. It also includes useful information for anyone interested in sentiment analysis and social media analysis. The widespread use of social networks and their role in modern society is one of the most interesting innovations in recent years. The close links that often arise between users create a space for discussions that motivate, engage, and unite people with common goals and encourage various forms of collective actions. Data from the web allows us to understand and explain many complex social phenomena and anticipate them. Only in the case that data is correctly collected and analysed. In this context, sentiment analysis tries to make clear what people think. Furthermore, it provides ideas, models, and algorithms that can turn unstructured text into informative data.

Telegram bot development based on with text-to-speech functions and text recognition from an images
(онлайн, 2022) Aksonov Denys; Vysotska Victoria
The goal is to develop a telegram bot that will have the functionality to convert text to voice message and recognise text from images. Currently, photo text recognition is an urgent task. It will expand the functionality of the telegram even more, and people can receive the finished text without leaving the application and without using different services for this, which takes more time. The object of further research is the process of text converted into a voice message and the recognition of text from images. The research subject is methods and tools to receive a message with text that will be read from a picture sent by the user and accept a voice message in response to the text sent by the user. Not many telegram bots can recognise text from a photo or convert text to a voice message, but no bot can perform these two functions simultaneously.

Multilingual voice user’s messages recognising and translating based on telegram bot and speech-to-text technology
(онлайн, 2022) Aksonov Denys; Vysotska Victoria
Converting users’ voice messages into text is an urgent task because it is very convenient. Many people send voice messages because it saves users time. After all, writing text by hand is a longer process than recording a voice. But there are cases when the people to whom thevoice message was sent do not have the opportunity to listen to it. It becomes a severe problem when the user thinks there may be something fundamental in this message, and the thought of it will not give him peace of mind until he can listen to it. At this point, a telegram bot that I will develop during this course may come to the rescue. The user will send the received voice message to the Bot, which with its functionality, will convert the voice into text, which will be sent to the user after the conversion. It allows the user to learn about the contents of the voice message without listening to it. The object of further research is the conversion of users’ voice messages into text. The study subject is to send a message with the text that will be received as a voice message conversion result that will be received from the Bot user.

In the study, using today's advanced technologies, a smart robot vacuum cleaner design and simulation is presented that will make people's lives easier and help them with cleaning. Accordingly, in the smart vacuum cleaner design we will make, our robot will have the ability to move autonomously, independent of human beings. While it moves autonomously, it will detect the objects around it with the sensors we use and avoid possible collisions. And in the simulation program we will use, it will create a map of the environment it is in and mark the locations of the objects here. Our project consists of two main parts. The first of these is the creation of a mechanical and electronic prototype of the robot, and the other is the simulation of the robot for location determination and mapping processes in the simulation environment as future work. In addition, in our project, we will develop a mobile application that runs on the Android operating system and will enable the robot and the user to communicate via the Bluetooth module. Through this mobile application, which will have certain modes, the user will be able to take control of the robot manually whenever he wants, and he will be able to make the robot move autonomously again whenever he wants.
