Contrast between live dubbing and AI dubbing: which one is more realistic and closer to human nature

Introduction In the digital age, images and sounds are the basic elements of human composition. So, in a society that values ​​speed and efficiency, the dubbing industry is undergoing tremendous changes. In ancient times, dubbing was done by real people, but now, artificial intelligence (AI) technology allows people to have more variety and variety when choosing audio. And these two ways are different, today we will discuss their relationship and see which way is more suitable for us! What is live dubbing? Dubbing done by a real person, as the name suggests, is a re-recording of the audio track of a film or video by a real person. Live voice dubbing is usually done by professional voice actors who put their voices into a library and then record them for various films or videos. The process of live dubbing usually includes steps such as script, character analysis, sound effect import, and audio production. Advantages of live dubbing The advantages of live dubbing are obvious. First of all, the tone, volume and speed of live dubbing can be controlled, so it has a greater range of variation. Secondly, the sound quality of live dubbing has a high degree of reproduction, especially the voice actors have a very keen sense of sound, and can further improve the degree of sound quality reproduction by adjusting parameters such as intonation and volume, making it more realistic and personalized. Disadvantages of live dubbing The production process of live dubbing requires a lot of time and manpower, which not only increases the cost, but also affects the entire production process. In addition, there are limitations in live dubbing, that is, it can only be done by specific voice actors. Therefore, this limits the choice and variety of audio. Also, due to human limitations, such as fatigue, voice instability, etc., can affect the performance of voice actors, reducing the possibility of achieving consistency and stability. What is AI dubbing? AI dubbing is an audio generation technology based on artificial intelligence, which generates sound for movies and videos through machine learning, neural network and other technologies. The basic principle of AI dubbing is to extract the sound features of existing audio, then train the neural network model, and finally generate more personalized audio. Advantages of AI dubbing Compared with real dubbing, the biggest advantage of AI dubbing is its high degree of automation and fast production speed. The whole process can be automated by computer, which not only saves time and labor costs, but also enables faster generation of large volumes of audio. In addition, the diversity and personalized options of AI dubbing are also very rich, and audio can be customized to better meet our needs. Disadvantages of AI dubbing The disadvantage of AI dubbing is mainly that the sound quality of the finished audio is relatively low, because it is only a sound generated by an algorithm, and has no real vitality and personality. There is also a certain regularity in AI dubbing, because it is based on the audio generated by the trained data set, while other factors are not taken into consideration, such as the specific scene background, the emotional color of the text/lines, etc., so sometimes its audio may It will look a bit single or even dull. The comparison between human dubbing and AI dubbing In the field of audio generation, there are some differences between human dubbing and AI dubbing. Acoustic reproduction This is the biggest difference between the two methods of audio generation. The sound quality of live dubbing is significantly higher, because the performance of the dubbing actor can organically integrate various sound variable elements such as intonation, volume, speed, etc., presenting a more realistic and dynamic audio effect. AI-generated audio is often imprecise in detail, and issues such as audio backgrounds and sound textures are not well represented. Operational speed Live dubbing requires more manpower and time, because they need to carefully analyze the lines and character images, and then perform operations such as recording for them. AI dubbing requires less operation time, and can be automated through computer programs, saving time and cost, and can also generate a large amount of audio, making the entire work process faster and more efficient. Personality selection and diversity In the process of dubbing, live dubbing can only be done by specific dubbing actors, and issues such as their expressive ability and voice characteristics must be considered. Therefore, there are relatively few individual choices and diversity in the works. AI dubbing does not need to consider these constraints, and can generate richer and personalized audio selections as needed. Applicable scenes Live dubbing is mainly suitable for audio scenes that focus on sound quality reproduction, rhythm and language perception, such as advertisements, films, videos, etc. AI dubbing is more suitable for generating personalized, real-time or different audio every day, such as intelligent customer service, voice assistant, online teaching and other fields.
