Analysis for Vibrato with Arbitrary Shape and its Applications to Music
Vibrato in singing voice and instrument performance is essential for perceived quality. It also creates individual performer styles. Over the years, vocal teachers and musicians often examine this musical characteristic by hand. This results in limited scope of music pieces being analyzed. This paper presents a vibrato analysis method, which is suitable for vibrato tones with arbitrary shape and quantitative analysis, enabling various music applications. To evaluate the performance of the proposed analysis method, we have conducted an experiment on estimation accuracy. It is shown that the error of estimating rate and extent are less than or equal to 6％ and 9％, respectively. Some applications of the analysis results, namely, vibrato analysis and singing synthesis, are presented at the end.
