Abstract: An electronic musical instrument includes a performance operator and at least one processor. In accordance with pitch data associated with the performance operator operated by a user, the at least one processor digitally synthesizes and outputs inferential musical sound data including inferential performance technique of a player. The inferential performance technique of the player is based on acoustic feature data output by a trained acoustic model obtained by performing machine learning on: a training score data set including training pitch data; and a training performance data set obtained by the player playing a musical instrument and is not played in the user operation of the performance operator.

Abstract: An electronic musical instrument includes: a memory that stores a machine-learning trained acoustic model mimicking voice of a singer and at least one processor. When a vocoder mode is on, prescribed lyric data and pitch data corresponding to a user operation of an operation element of the musical instrument are inputted to the trained acoustic model, and inferred singing voice data that infers a singing voice of the singer is synthesized on the basis of acoustic feature data output by the trained acoustic model and on the basis of instrument sound waveform data that are synthesized in accordance with the pitch data corresponding to the user operation of the operation element. When the vocoder mode is off, the inferred singing voice data is synthesized based on the acoustic feature data without using the sound waveform data.

Abstract: An electronic musical instrument outputs synthesized lyrics of a song based on lyric data in accordance with operations by a user. One or more processors in electronic musical instrument generate voice synthesis data for a lyric of the song based on the lyric data for the song at a timing at which said lyric is supposed to be outputted regardless of whether or not a user operation of the operating unit is detected at said timing; when the user operation of the operating unit is detected at said timing, cause voice sound synthesized based on the generated voice synthesis data to be outputted; and when the user operation of the operating unit is not detected at said timing, cause the voice sound synthesized based on the generated voice synthesis data not to be outputted.
