Abstract (in Japanese) (See Japanese page) 
(in English) We introduce a real-time and interactive tool for visualizing voice-source attributes. The tool provides a simplified calibration procedure based on the recommendation on acoustic analyses of pathological voices. The real-time analysis uses a periodicity analysis algorithm based on analytic signals with the envelope made from the six-term cosine series. The visualization uses pseudo color for representing attributes on the Voice Range Profile (VRP) as the third dimension. The attributes consist of the Cepstral Peak Prominence (CPP), H1-H2.The tool and related materials are on the GitHub repository as an open-source.
