This involves complex processes such as phoneme recognition, timing adjustment, and synchronization to ensure that the audio fits perfectly with the visual cues.
- Application in Production
This technology is widely used in dubbing films, creating multilingual marketing videos, and producing educational content that requires accurate translation. It allows for seamless integration of translated audio, ensuring that the final product is professional and polished.
