Application: Information processing device and control method thereof (Patent ID: US20230419932A1)
The patent filed by Yamaha Corp describes an information processing device that includes modules for inputting natural language containing adjectives and estimating timbre data based on this input. The device uses a trained model to output timbre data from the adjective provided by the user. The system can present multiple timbre data options to the user for selection, including waveform data, effect parameters, or a combination of both, with the ability to generate sounds based on these selections.
Additionally, the patent outlines a control method, realized by a computer, that involves acquiring natural language input with adjectives from a user and outputting timbre data using a trained model. The method includes presenting multiple timbre data options to the user, sounding these options, and allowing the user to select one. The system can further train the model based on user selections and input from the natural language. The method also involves obtaining latent variables from a latent space tagged with adjectives in the input natural language to generate the timbre data. Overall, the patent describes a comprehensive system for processing natural language input to estimate and present timbre data options for user selection.
