階層的データ構造による音脈表現 : 音脈分凝の計算モデル The Representation of Sound Streams Using Hierarchical Data Structure : A Computational Model of Sound Stream Segregation
We propose a new model of sound stream segregation by using amplitude co-modulation and frequency co-modulation as auditory cues. This model adopts a hierarchical data structure which has not been used explicitly in the previous models of sound stream segregation. As a result, the hierarchies of streams were naturally represented in this model. In addition, this model is considered to have a potential of real-time processing and to give easy handling of adding constraints on sounds to be segregeted owing to modularity than previous modds did.
