Spectral Continuity Measures at Mandarin Syllable Boundaries

Jun Xu, Lianhong Cai

In Text-to-Speech (TTS) systems based on concatenative synthesis, the naturalness of synthetic speech is highly affected by the spectral continuities at the concatenation point. In this paper, we focused on 4 kinds of syllable boundaries in mandarin and used several spectral distance measures combined with time derivatives distance measures to predict their audible discontinuities. A perceptual test is also proposed to evaluate the efficiencies of these measures.
