Abstract: Traditional studies on bel canto resonance rely mainly on subjective auditory evaluation, lacking standardised quantitative methods. It is difficult to accurately capture the internal correlations and variation patterns of multi-scale resonance characteristics, it also makes the optimisation of bel canto teaching and singing skills lack of scientific quantitative basis. To address this issue, this paper proposes a dedicated multi-scale feature extraction algorithm and an attention-based feature fusion algorithm. Combined with acoustic experiments on soprano singing signals, we conduct a systematic quantitative study. Results show that this method can effectively extract multi-scale features of bel canto resonance. The recognition rate of the fused features for bel canto vocal types is significantly higher than that of the single feature, and the average recognition rate of all vowels is more than 90%, which can accurately reveal the characteristic distribution of bel canto resonance.
Keywords: bel canto; resonance characteristics; multiscale feature; acoustic quantitative analysis.
