Researchers have developed UR-BERT, a novel text encoder designed to significantly expand the capabilities of massively multilingual text-to-speech (TTS) systems. Unlike traditional methods limited by grapheme-to-phoneme resources, UR-BERT unifies diverse writing systems into a common Romanization format, enabling support for 495 languages. The system also incorporates a speech token prediction objective to improve phonetic accuracy and text-speech alignment, demonstrating superior performance over existing baselines and strong generalization to new languages.
