LuxEmo: 21-hour expressive speech corpus for Luxembourgish TTS with emotion categories

Researchers introduce LuxEmo, a 21-hour conversational speech corpus for Luxembourgish derived from RTL youth broadcasts, annotated with four emotion categories via a semi-automatic curation pipeline combining VAD, denoising, language ID, and human validation. The paper benchmarks five expressive TTS systems across cross-lingual transfer, multilingual support, and prosody transfer approaches. The work addresses the underrepresentation of low-resource languages in speech technology research.
