[Retracted] A Deep Learning-Based Piano Music Notation Recognition Method

Table 1

Deviation of main parameters of music notation recognition and the original speech (unit: %).

Audio	Parameters	Pitch	Rate	Tempo
Piano music	Center frequency	6.29	4.50	0.59
	Bandwidth	26.01	66.69	63.95
	Intensity	−9.99	0.65	−10.12
Overall absolute deviation = 20.97 overall reduction fitting rate = 79.03
English pronunciation	Center frequency	0.50	−2.11	−0.36
	Bandwidth	49.33	72.01	29.55
	Intensity	−11.22	−10.98	12.88
Overall absolute deviation = 20.97 overall reduction fitting rate = 79.03

Note: overall restoration fit rate = 100% − overall absolute deviation.
