If you want to bring emotion, the first point is to read through the dubbing copy, study every detail of the copy, and understand the psychological activities of the dubbing role in order to substitute it better. Secondly, we can refer to people with similar attributes (such as identity and work) and observe their usual behavior and tone of voice, which will also be helpful for dubbing. Third, we should exercise for a long time. It is by no means a day's work to achieve something in dubbing. After accumulating certain experience, it will be much easier to replace emotions with certain control of role types.
