Abstract

<p>This paper introduces a new fine-grained voice source analysis method and its application to filled pause analysis in the CSJ (Corpus of Spontaneous Japanese). The new source analysis procedure is designed to provide annotation with reliable and precise descriptions of objective characteristics to items in large speech corpora. This design target made the new analysis method provide far more accurate descriptions than existing methods. The new method provides the fundamental frequency estimate and the band-wise aperiodicity information simultaneously. It also provides an information-rich representation of a probability map of the fundamental component. This paper presents several analysis examples and discussions.</p>
