PROBLEM TO BE SOLVED: To realize a flexible as well as versatile note division for a character string of a lyric.SOLUTION: A note string setting section 24 sets a specific note string M which is suitable for a specified character string X having a plurality of sound units x[n] arranged in time series. An analysis processing section 30 generates a connection information string Y having connection information y[n] arranged in time series for specifying the presence or absence of connection in the respective sound units x[n] which occur one after another in the specified character string X for every sound unit x[n] by applying a probability model generated by prior machine learning to the specified character string X. The probability model is set by the machine learning using a plurality of learning data including a character string XL for learning having a plurality of sound units x[n] arranged in time series and a connection information string YL having a plurality of connection information y[n] arranged in time series. A note string acquiring section 40 acquires the specific note string M which has a plurality of notes corresponding to respective note division units z[m] acquired by applying the presence or absence of connection specified by the connection information string Y to the respective sound units x[n] of a specified character string X arranged in time series. |
