摘要

PROBLEM TO BE SOLVED: To provide a performance information prediction device, a performance model training device, a performance information generation system, a performance information prediction method and a performance model training method for converting the performance of an electronic stringed instrument into performance information with high accuracy. SOLUTION: In a performance information prediction device, a preprocessing unit 310 for generating a spectrum data frame from string vibration waveform data representing a string instrument performance and acquiring a spectrum featured data frame based on the spectrum data frame, and a trained performance. Using the model, the performance information prediction unit 320 that predicts the performance information of the string instrument performance from the spectral featured data frame of the reference time and the spectral featured data frames before and after the spectral featured data frame of the reference time, and Has.
