Description

Technical Field

[0001] The utility model relates to the field of popular science exhibition preparation, in particular to a popular science experimental device for simulating dubbing. Background Art

[0002] Dubbing is the process of adding sound to a film and is a crucial step in animation production. The quality of dubbing directly impacts the overall quality of the animation. Dubbing for animation involves re-recording voices after the animation is complete, adding appropriate dialogue and background sound effects to the characters. Early animation productions were done manually. This method was extremely time-consuming and labor-intensive, requiring the voice artist to perfectly blend their voice with the characters to achieve the best possible effect. During this period, voice artists underwent multiple studio auditions and adjustments to ensure a perfect integration with the animation's visuals. Currently, digital dubbing is increasingly being used. While this technology improves the efficiency of animation dubbing, it lacks the opportunity for public exploration and reflection. Existing digital dubbing methods prevent those interested in dubbing from manually exploring and experimenting. They also lack understanding of the specific principles of dubbing, the specific dubbing tools used for different sound effects, and the differences in timbre, rhythm, and rhythm of each tool.
