In Mandarin, there is a special acoustic feature°™tonal pitch range, which is relative to stress. In this paper, we present a novel concept-tonal range ratio (TRR), which is based on tonal pitch range, and make a study on the correlation between TRR and stress in Mandarin. And we developed a system to automatically detect stresses in words and sentences based on TRR in Mandarin. We obtained high success rate (92.67% in words and 82.0% in sentences). The results show that TRR has strong correlation with stress and is powerful in detecting stresses in Mandarin.
