Application of synchronous isolation for evaluating the similarity of vocal performances

Authors: Kataeva E. S., Yakimuk A. Yu.

Annotation: This paper presents the results of applying the method of extracting synchronism, developed specifically to assess the degree of synchronism of time series. The results for the series of frequencies of the fundamental tone obtained by processing vocal recordings of the same melody by different performers. The study examined six different kernel functions for the approximation problem. Empirically identified kernel, the use of which the accuracy of the assessment above, that allows us to apply this method in the field of singing training with specialized programs and for automating the assessment of speech quality of patients after treatment of oncological diseases of the speech-forming tract.

Keywords: vocal performance, synchronicity, approximation of temporary types, speech technology
