AI 虛擬主播怎麼做？HeyGen、Synthesia 教學與應用
不用出鏡、不用攝影棚，就能做出有真人主播的影片。這篇帶你了解 AI 虛擬主播的做法與用途。
What is an AI Virtual Host
An AI virtual host (AI avatar) can generate a video of a "real person" speaking in front of a camera using a typed script, and also provide multi-language dubbing. It's especially convenient for creating tutorials, product introductions, and corporate training materials.
Mainstream Tools
- HeyGen: Excels at natural virtual hosting and multi-language dubbing, and can also create digital clones.
- Synthesia: A representative enterprise-level tool, stable and reliable, with many templates, suitable for educational training.

Production Process
- Write a script (can be assisted by ChatGPT).
- Choose a virtual host and language.
- Paste the script and generate the video.
- Add brand intros, subtitles, and backgrounds.
Suitable Applications
- Online courses and tutorial videos
- Product feature introductions and operational guides
- Corporate internal training and announcements
- Multi-language marketing videos (for international content)
Things to Note
- Authenticity and Disclosure: When used for formal communication, it's best to moderately inform the audience that it's AI-generated.
- Digital Clone Licensing: When using a human likeness (including your own clone), be sure to obtain consent.
- Avoiding the Uncanny Valley: Using colloquial language in scripts and natural speech speeds can greatly improve the effect.
Conclusion
AI virtual hosts have reduced the cost of producing "talking head" videos to a very low level, making them especially suitable for teams that need to produce a large number of standardized, multi-language videos. First, test the audience's acceptance, and then decide whether to scale up. For further reading: Using AI-Generated Videos for Marketing.
