A new study published on arXiv introduces a comprehensive benchmarking framework for evaluating text-to-speech (TTS) systems, particularly focusing on low-resource languages and diverse speech domains. The research evaluated four state-of-the-art TTS systems—Indic Parler-TTS, MMS TTS, Microsoft Edge TTS, and Google Gemini TTS—using a combination of subjective listening tests, speaker similarity scoring, and acoustic analyses. The findings indicate significant performance variations across domains, with emotional speech posing the greatest challenge and conversational speech showing the highest acoustic fidelity. The study also emphasizes reproducibility by releasing evaluation scripts and data to facilitate standardized TTS benchmarking. AI
IMPACT Provides a standardized method for evaluating TTS systems, potentially accelerating improvements in speech synthesis for low-resource languages.
