摘要： 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.

摘要： An electronic musical instrument includes: a plurality of keys that include at least first keys corresponding to a first pitch range and second keys corresponding to a second pitch range; and at least one processor, configured to perform the following: causing a syllable position in a phrase that is digitally synthesized for output to be not advanced no matter how the second keys in the second pitch range are operated while a key operation in the first pitch range is being continuously maintained; and causing the syllable position to advance every time a key operation in the second pitch rang is performed while none of the first keys in the first pitch range are being operated.

摘要： 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.
