The intonation of Bangla sentences: Declarative, Wh-questions and yes/no by using Empirical Mode of Decomposition

This paper investigates the intonational properties of different types of sentence by using EMD analysis of Bangla language. The study is about yes/no questions, wh-questions and declarative sentences. The speech material used for the present study is 45 read utterances recorded in laboratory conditions. The result shows that the intonation pattern for declarative sentences is falling, wh-questions also follow the same intonation pattern as declarative, but for yes/no it´s rising. The other parameters of intonation pattern such as stressed word and intermediate phrase also studied. The results of EMD analysis is then compared with the Bangla grammar and Fujisaki model, which are satisfactory.
