Information processing method, information processing device, and program

An information processing device comprising:

• an electronic controller including at least one processor,
• the electronic controller being configured to
• generate a first characteristic transition which is a transition of an acoustic characteristic, in accordance with an instruction from a user,
• generate a second characteristic transition which is a transition of an acoustic characteristic of voice that is pronounced in a specific pronunciation style selected from a plurality of pronunciation styles,
• set, in accordance with an instruction from the user, a first weighted value for the first characteristic transition and a second weighted value for the second characteristic transition, and calculate a weighted sum of the first characteristic transition and the second characteristic transition by using the first weighted value and the second weighted value, and
• generate a combined characteristic transition which is a transition of an acoustic characteristic of synthesized voice, by combining the first characteristic transition and the second characteristic transition using the weighted sum,
• the acoustic characteristic for the first characteristic transition, the acoustic characteristic of the voice for the second characteristic transition, and the acoustic characteristic of the synthesized voice for the combined characteristic transition being the same acoustic characteristic.

A non-transitory computer-readable medium storing a program that causes a computer to execute a process, the process comprising:

• generating a first characteristic transition which is a transition of an acoustic characteristic, in accordance with an instruction from a user;
• generating a second characteristic transition which is a transition of an acoustic characteristic of voice that is pronounced in a specific pronunciation style;
• setting, in accordance with an instruction from the user, a first weighted value for the first characteristic transition and a second weighted value for the second characteristic transition, and calculating a weighted sum of the first characteristic transition and the second characteristic transition by using the first weighted value and the second weighted value;
• and
• generating a combined characteristic transition which is a transition of an acoustic characteristic of synthesized voice, by combining the first characteristic transition and the second characteristic transition using the weighted sum,
• the acoustic characteristic for the first characteristic transition, the acoustic characteristic of the voice for the second characteristic transition, and the acoustic characteristic of the synthesized voice for the combined characteristic transition being the same acoustic characteristic.
