    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.
