In recent years, AI tool platforms have sprung up everywhere, providing various solutions for small and medium-sized enterprises. They are relatively economical and affordable. It is really recommended to take some time to study these tools carefully. Having trained many Taiwanese small and medium-sized enterprises internally and operating them painstakingly for many years, they have strong core product manufacturing capabilities, which is not easy for them to face the ever-changing international market. However, companies are often small in scale and find it relatively difficult to recruit talent. They may not have enough budget or scale to recruit professional marketing talent. In a company, whether an employee or a boss, one person often has to play multiple roles. The boss is also the salesperson, the salesperson is also the marketing person, the salesperson is also the accountant, the technician is also the HR person… and so on. This situation is very common. Not to mention having a spokesperson for the product, or having enough budget to produce relatively high-quality product advertisements. The tools introduced today are not only suitable for B2C, but also for B2B. We can use virtual spokespersons and videos to introduce how our parts, molds, and even large machines work. It is also very suitable for use in PowerPoint presentations, making our presentations more vivid. Now let’s take a look at what AI tools can help us not only create product spokespersons, but also introduce our products through animations.

Comparison of HeyGen, Synthesia and D-ID
Basically, such platforms are based on the Text-to-speech (TTS) function, allowing the AI spokesperson (anchor) to produce speaking videos. You can choose the platform based on the functions you need most:
- Pursuing natural speech: Among the three platforms, HeyGen’s speaking mouth shapes and facial expressions and movements look the most natural. However, Synthesia and D-ID currently have a certain level and are constantly improving.
- The selectivity of AI avatar: Synthesia has the most, the number of HeyGen is not much different, and D-ID can be generated by AI. It depends on whether you like the actors they offer.
- Pursue a customized AI avatar : This means you can clone yourself, or clone someone else (with respect for the portrait rights), to serve as your virtual spokesperson. HeyGen can clone your image using video , which is relatively natural, and the entry-level price allows you to create 3 clones. Synthesia and D-ID mainly use pictures to clone images, which is less natural. The free entry version of D-ID can use pictures to clone images, but Synthesia requires an annual subscription.
- Pursuing diversified and professional templates : HeyGen templates are more oriented towards e-commerce advertising, while Synthesia’s current templates are more oriented towards To B and corporate internal training applications.
- Pursuing the convenience of media library integration: Synthesia provides more convenient media library integration
- Pursuing the convenience of integration with Canva: HeyGen and D-ID can be found and registered for trial directly in the Canva App, and the entry-level version has integration. Synthesia does not see relevant integration
- Pursuing ease of integration with PowerPoint: Synthesia (included in the lowest price) is better than >> HeyGen (included in the mid-range price) is better than >> D-ID (included in the advanced price)
- Need AI agent service: Currently, HeyGen and D-ID both provide AI agent services that are connected via API, but they are charged at an additional price and are not included in the original AI avatar fee.
- Pursuing the lowest price: The lowest entry price of D-ID is only NT$189/month, which is the cheapest among the three platforms, but there will be a watermark, which can be covered using a method
Overall, HeyGen has comprehensive functions. Synthesia provides a wide variety of business templates that are highly integrated with PowerPoint and are suitable for corporate use. D-ID has a low entry price and is suitable for small and medium-sized enterprises that use free resources such as Canva but need more independent creative capabilities.

AI Avatar use cases
1. B2B (Business to Business)
- Create audio-visual descriptions of product, machine or process features that include virtual characters
- Release the latest product or application introduction videos for dealers around the world
- Conduct Lead Qualification and filter the potential customer list: When an Inquiry comes in, we will generate Leads, which is the “potential customer list”. We can use AI virtual video customer service to initially contact customers for Lead Qualification, which is “potential customer list filtering”, and divide Leads into: SQL (Sales Qualified Leads business valid list), MQL (Marketing Qualified Leads marketing valid list), or UQ (Unqualified Leads invalid list). And combined with Marketing Automation, SQL is distributed to business colleagues, MQL is kept in the CRM list, and marketing colleagues can carry out subsequent marketing operations and Leads Nurturing (lead list management), so that MQL can be converted into SQL and have a real chance to become our customers.
Case: After consulting with a mechanical equipment manufacturer, the other party mentioned the difficulty of small and medium-sized enterprises in finding people. They could not find someone who was fluent in foreign languages and had many years of industry experience like him, who could contact the customer as soon as the inquiry came in and clarify whether the local power supply, water supply specifications and stability were suitable for the introduction of these equipment. Therefore, he was advised to document his own industry experience and use it to train AI. The resulting AI virtual audio and video customer service could assist him in presale operations and solve his years of pain. - External briefings: When business colleagues brief potential customers, they can use AI virtual spokespersons to more accurately and effectively explain the company’s product or service features. If the business personnel are more interested, they can also use their own images for A training, and let their virtual avatars explain it, which is more accurate and eye-catching.
- Digital advertising: Of course, if B2B purchases digital advertising, it can also use AI virtual spokespersons to become brand spokespersons to explain the product.
2. B2C (Business to Customer)
- Digital advertising: Using AI avatar to provide product video introductions
- New product launch/product usage introduction: Introduce new product launch/product usage to your new and old customers through product video introduction by AI avatar. Or your product really has a spokesperson. For example, we once consulted the well-known makeup artist Kevin’s own brand, and at that time we recommended training Kevin’s image and voice. Marketers can use Kevin’s image and voice to quickly produce videos, and even speak different languages, such as Cantonese, to explain to customers how to use the product, or the features of new products…etc. It can save the trouble of shooting a video by yourself every time, making the production of videos more efficient.
- AI customer service: Through AI training and learning, AI agent service can help answer and solve basic customer questions. Learn more about AI Agent Implementation Service from HeyaDigi.
3. Internal Use
- Internal training: company introduction for new employees, workplace public safety tips, workplace gender equality, company ESG policy, company information security policy, company procurement process, finance department payment process, etc.
- Various briefings: annual briefing, financial briefing of shareholders’ meeting, proposal briefing, etc. You can use any important briefing you want
- Internal professional courses: business skills, digital marketing operations, intellectual property rights, etc., all kinds of courses you can think of can be recorded into videos for new employees to learn and use
In fact, the AI tools on various platforms are iterating very quickly, and may change every 1-2 months to provide new and different features. Now there are many platforms, and they seem similar but are different. The competition is very fierce, but it also gives us the opportunity to use them at a more affordable price. Eventually, perhaps these platforms will go through a wave of integration, eliminating the weak and retaining the strong, and then we may not have so many choices.
