From English pitch accent detection to Mandarin stress detection, where is the difference?

Although English pitch accent detection has been studied extensively, there relatively a few works explore Mandarin stress etection. Moreover, the comparison and analysis between Mandarin stress detection and English pitch accent detection have not een touched for such counterpart tasks. In this paper, we discuss Mandarin stress detection and compare it with English pitch accent etection. The contributions of the paper are two aspects: one is that we use classifier combination method to detect Mandarin stress nd English pitch accent by using acoustic, lexical and syntactic evidence. Our proposed method achieves better performance on oth the Mandarin prosodic annotation corpus—ASCCD and the English prosodic annotation corpus—Boston University Radio ews Corpus (BURNC) when compared with the baseline system. We also verify our proposed method on other prosodic annotation orpus and continuous speech corpus. The other is the feature analysis. Duration, pitch, energy and intensity features are compared or Mandarin stress detection and English pitch accent detection. Based on the analysis of prosodic annotation corpora, we also erify some linguistic conclusions. 2011 Elsevier Ltd. All rights reserved.
