Fitting a 数字人 to your brand: face, voice, look and the rules that hold it together
The fastest way to waste a 数字人 is to make it generic: a polished stranger in a blazer reading a script that could belong to any company. Viewers scroll past because nothing about it says you. This last part of our series covers the four decisions that make an avatar feel like your brand rather than a template.
In this article
Decision 1: whose face
There are three choices, and they’re not equal.
- The owner. The strongest trust, because customers already know the face. The cost is that the brand becomes tied to one person, and the owner has to be comfortable seeing their avatar every week.
- A team member as brand host. One consistent person who fronts the social accounts, both live and as the avatar. The brand isn’t tied to the owner, and the host can also turn up for real at events and in videos. This is what we do ourselves.
- A stock or fully synthetic face. Cheapest and fastest, and the weakest. Nobody can meet this person, so the trust the avatar builds has nowhere to land. Avoid it for a service business.
Whichever you pick, get a short written agreement covering where the likeness is used and what happens if the person leaves. Decide that before the first clip, not after.
Decision 2: how it sounds
The voice is more of the brand than the face is. Three things to decide:
- Language. If your customers are mixed, decide which posts go out in English, which in 中文, and whether any go out in both. Don’t let the avatar switch languages at random.
- Register. Formal and careful, or warm and direct? Match how your best salesperson talks to customers, not how a corporate brochure reads.
- Words you always and never use. Write down five of each. “We’ll remind you” versus “the client is responsible” is a brand decision, and the avatar will repeat whatever the script says.
Scripts should be written the way your team actually speaks, then read aloud once by a real person before the avatar says them. If it sounds wrong in a human mouth, it sounds worse in an avatar’s.
Decision 3: how it looks on screen
- Wardrobe and setting that fit what you sell: a renovation firm’s host in a site jacket, an accounting firm’s host in an office, not the reverse.
- One frame, used every time: the same colours, logo position and subtitle style, so people recognise the post before they hear a word.
- Subtitles always on, in the post’s language. Most people watch on mute.
- Plain backgrounds over flashy ones. Busy effects make an avatar’s small imperfections more noticeable, not less.
Decision 4: the rules it follows
Write these down so whoever makes the clips follows the same rules every time:
- What the avatar is for: announcements, reminders, routine FAQs. What it’s never for: testimonials, apologies, anything live. (Part four of the series, on disclosure, covers why.)
- Every avatar clip is labelled, on the platform and in the caption.
- The real person appears at least once a week, so the avatar stays a convenience, not a replacement.
- One person approves every script before it’s made.
Test it before you commit
Before the avatar goes on your main account, make three clips and show them to five real customers. Ask two questions: “Does this sound like us?” and “Would you watch to the end?” If the answers are lukewarm, fix the script and voice first. That’s nearly always where the problem is, not the avatar itself.
Where we come in
Our branding and social media service sets up all four decisions with you: choosing and agreeing the host, writing the voice guide and scripts, building the on-screen frame, and running the monthly mix of avatar and real-person posts. If you’re new to the series, start with what a 数字人 is, or take our one-minute branding check.
Common questions
Should my 数字人 be me or a staff member?
The owner gives the strongest trust but ties the brand to one person. A consistent team member as brand host keeps the brand independent and can also appear live. Avoid stock or synthetic faces for a service business.
Should my 数字人 speak English or Chinese?
Decide by audience and post type, and keep it consistent. Many Singapore SMEs run some posts in English and some in Chinese. The avatar shouldn't switch languages at random.
How do I make an AI avatar look on-brand?
Use the same frame every time: colours, logo position and subtitle style. Match wardrobe and setting to what you sell, and keep backgrounds plain.
What should be in a 数字人 brand guide?
Whose face it is and the likeness agreement, language and tone, words you always and never use, the visual frame, what the avatar is and isn't used for, labelling, and who approves scripts.
How do I know if my 数字人 is working?
Before launch, show three clips to five real customers and ask if it sounds like you and whether they'd watch to the end. After launch, watch saves and replies, not just views.
