Abstract

      This paper presents a software system designed for real-time translation of spoken Ukrainian into sign language animations. The system employs the Whisper model for automatic speech recognition (ASR), ensuring reliable transcription of oral Ukrainian. Given that the Ukrainian language is highly inflected while sign language does not utilize grammatical cases, a JSON-based correction module has been implemented. This module consists of two components: a dictionary for frequent recognition errors and a lemmatization mechanism that converts words into their base forms. The normalized text is subsequently mapped to GIF animations, each representing a corresponding sign in Ukrainian Sign Language (USL). The translation process operates in real time, providing a sequential display of animations synchronized with the recognized speech. The solution demonstrates both technical efficiency—characterized by low latency and a modular architecture—and social impact by enhancing communication accessibility for individuals who are d/Deaf or hard of hearing, as well as those who use sign language as their primary means of communication. Potential applications include inclusive education, everyday interactions, and the development of assistive technologies tailored to the needs of the signing community.
