Abstract: A voice synthesis method includes: supplying a first trained model with control data including phonetic identifier data to generate a series of frequency spectra of harmonic components; supplying a second trained model with the control data to generate a waveform signal representative of non-harmonic components; and generating a voice signal including the harmonic components and the non-harmonic components based on the series of frequency spectra of the harmonic components generated by the first trained model and the waveform signal representative of the non-harmonic components generated by the second trained model.

Abstract: First time-series data is edited according to a first user instruction, and second time-series data representing a series of features and generated based on the edited first time-series data is edited according to a second user instruction. In response to editing of the first time-series data, the edited first time-series data is saved as a new version in first history data. In response to editing of the second time-series data, the edited second time-series data is saved as a new version in second history data. A first version number and a second version number are designated according to a third user instruction. Third time-series data representing content corresponding to the first time-series data is then generated by using the first version of first time-series data in the first history data, and the second version of second time-series data in the second history data.
