Abstract (in Japanese) (See Japanese page) 
(in English) We have developed real-time analysis tool for acoustic features of singing voice that is thought to be related to singing skill level. The sound input from microphone or mixer, and can analyze from start to end. The singing voice difference between professional and amateur is clearly distinguished by using SFR (Second Formant Ratio) and Q (sharpness of singer's formant) graph of these features we already reported. To do a more detailed analysis, sound file input version was also made. There is singing data of various bands on the Internet. To evaluate those data on the same SFR-Q scale, the analysis condition is proposed. This tool is not only for analysis, but can also for vocal training lesson and self-training assistance.
