MOBILE APPLICATION FOR IDENTIFYING BIRDS BY SOUND SIGNALS

GitHub Backend GitHub mobile GitHub ML

Technologies used: Java, Python, Swift, SpringBoot, Hibernate, PostgreSQL, FastAPI, SwiftUI

In this work, approaches to acoustic recognition of bird species are analysed and their applicability in mobile devices is investigated.
Based on the results obtained, a full-fledged mobile application for identifying birds by sound signals in real time has been developed.
Created to solve the task of identification by sound signal, the application proved its effectiveness as a result of testing.
The implemented mobile application fully complies with technical specifications, user interface requirements, as well as clean
architecture and modularity standards.
The software product was implemented using SwiftUI, Spring Boot 3 with PostgreSQL, as well as a separate ML service on FastAPI
with the ConvNeXt neural network. All components are containerised using Docker.
