X-Translator: Open-Source Real-Time Multilingual Speaker-Aware Speech-to-Speech Translation
Researchers present X-Translator, a modular, low-cost, open-source speech-to-speech translation system that integrates streaming automatic speech recognition (ASR), machine translation, and prompt-conditioned text-to-speech (TTS). The system is designed for real-time translation in long-form and multi-speaker conversations, addressing challenges such as unstable ASR hypotheses, ambiguous turn boundaries, and speaker consistency. X-Translator is evaluated on translation quality, speech quality, latency, and speaker preservation, with code and a demo publicly available.
Why it matters: X-Translator offers an open, reproducible platform for real-time multilingual speech translation with speaker awareness, helping advance practical deployment in complex conversational scenarios.
