With the development of artificial intelligence (AI) technology, the perspectives and user experiences of movie commentary short videos have undergone significant changes. The application of voice cloning technology (such as Alibaba’s CosyVoice and ByteDance’s MegaTTS3) and sentiment analysis technology has enabled commentary videos to enhance viewers’ emotional involvement through a first-person perspective. AI voice synthesis technology precisely replicates actors’ voices and emotions, allowing audiences to feel the characters’ inner world more realistically. Furthermore, AI can generate personalized monologues based on characters’ personalities and the storyline, improving the emotional expression’s subtlety. Research shows that videos with high-quality background music and emotional fluctuations can quickly capture viewers’ attention, especially in a fast-paced cultural context, where the audiovisual impact of the video is crucial. By combining large language models and speech synthesis technologies, AI not only enhances the emotional depth of the movie plot but also improves the audience’s sense of immersion. The application of the first-person perspective breaks away from the traditional third-person narrative, allowing viewers to resonate emotionally with the movie characters directly and enhancing the viewing experience. At the same time, how to balance technological innovation and content depth, avoiding content monotony and excessive emotional expression, has become an important issue for future development.
