Glottal Activity is defined by the process of exciting the vocal tract system by the vibration of the vocal folds during speech processing. Detection of glottal activity refers to identifying the glottal instants present within a glottal cycle. GCI and GOI are the two important glottal instants of a…
This paper proposes a new approach of modeling the excitation signal as deterministic and noise components. Initially, a study on characteristics of excitation or residual signal around glottal closure instant (GCI) is performed using principal component analysis (PCA). Based on the study, the segme…
A combined spectro-temporal based method is proposed to derive the predominant melody from vocal polyphonic music signals. In the proposed method, vocal (voiced) and non-vocal (unvoiced) segments are determined by strength of excitation. The vocal segments are further divided into voiced notes by de…
