Document Type and Number:
WIPO Patent Application WO/2022/054496
Kind Code:
A1
Abstract:
This invention relates to: an electronic musical instrument that reproduces a singing voice in accordance with the operation of an operation device such as a keyboard; an electronic musical instrument control method; and a program. The invention enables deduction of an appropriate sound waveform matched to a change in the time between notes changing in real time. An electronic musical instrument (100) comprises: a pitch designation unit (602) that outputs performance time pitch data (610) designated at the time of performance; a performance style output unit (603) that outputs performance time performance style data (611) indicating the performance style at the time of performance; and a pronunciation model unit (308) that, on the basis of an acoustic model parameter deduced by inputting the performance time pitch data (610) and the performance time performance style data (611) to a trained acoustic model, synthesizes and outputs musical tone data corresponding to the performance time pitch data (610) and the performance time performance style data (611).
