SekoTalk

• 1. overview (446 chars)

  SekoTalk is an AI lip-sync video creation tool launched by SenseTime’s Seko intelligent platform and will be launched in August 2025. This product can automatically generate matching mouth animations based on the audio provided by the user, supports multiple languages ​​​​such as Chinese, English, Japanese, Korean, etc., and can also enable up to 3 people to talk on the same screen. As of November 2025, SekoTalk has more than 100,000 registered creators, providing an efficient solution for digital human content creation.

• 2. Product background (858 chars)

  SekoTalk is developed by SenseTime, a listed artificial intelligence company. Founded in 2014, SenseTime is a leading domestic computer vision and deep learning technology company and was listed on the Hong Kong Stock Exchange in 2020. As the core component of the Seko agent platform, SekoTalk is deeply integrated with the platform's script generation, video generation and other functions, providing a complete workflow from creative planning to lip sync generation.   SenseTime Technology has deep accumulation in the fields of generative AI and multi-modal interaction, and its digital human technology has been applied to products such as SenseTime Ruying Digital Human and Seko video creation platform. SekoTalk's R&D breakthrough stems from the deep integration of generative AI and speech recognition technology. By building a three-dimensional sound field modeling system and combining it with a dynamic neural network optimization algorithm, it achieves efficient lip synchronization effects.

• 3. Product functions and usage experience (2484 chars)

  Core functions   Multilingual lip-sync generation is SekoTalk’s core technical capability. This tool can automatically analyze phonemes, rhythm and subtle pronunciation features in audio and map them to corresponding mouth movements. According to user feedback, the product has the highest accuracy in recognizing the speech speed of daily conversations, and can also maintain good synchronization with extreme styles of singing such as high-speed rap, Peking opera, and bel canto. However, there may be slight deviations in extreme cases.   Multi-role support is the highlight feature of the product. SekoTalk can identify different speakers in the audio, generate independent lip-sync movements for each character, support up to 3 people talking on the same screen, and naturally present eye contact and body language between characters. This function solves the industry problem of lip-syncing in multi-person scenes in AI video creation, and avoids the "collective mouth movement" phenomenon that was common in the past.   Long video stability is an important advantage of the product. The free version supports audio up to 60 seconds, and the paid version can handle audio input up to 15 minutes, and can still maintain lip synchronization accuracy and picture stability in long video scenes. SenseTime test data shows that the character consistency in the 10-minute short drama reaches 98%.   The character customization function allows users to choose from the built-in character library (covering real people, cartoons, virtual idols, pets, etc.), or upload custom character pictures for mouth shape generation (clear, front-facing photos are recommended). In addition, users can also adjust the character's movement performance by describing actions in natural language (such as "waving," "nodding," "smiling," and "sit down").   Usage process   The process of using SekoTalk is very simple: the first step is to visit the official website to register and log in; the second step is to describe the video creative idea in natural language, and the system automatically completes the entire process from script understanding to lip sync generation; the third step is to use the built-in canvas editing interface to preview and adjust the lip sync effect; and finally export the video. Zero learning curve is the main reason why users choose this product.   Technical features   The product is built based on core technologies such as AI audio analysis, Voiceprint voiceprint recognition, and role consistency algorithms. The cloud-native architecture requires no local installation, is accessible via a browser, and is deeply integrated with the Seko platform’s end-to-end video creation process.   According to public information, SekoTalk has excellent technical indicators: the inference speed reaches 25fps and the first frame delay is only 3.5s, providing technical support for real-time voice digital human applications.

• 4. Pricing and business model (454 chars)

  SekoTalk adopts a freemium model. The free version provides a 60-second audio duration limit and is suitable for light users’ first experience and simple content creation. The paid version supports longer audio (up to 15 minutes) and higher concurrent processing capabilities, making it suitable for commercial content creation and high-frequency usage scenarios.   The specific payment price information has not been disclosed in public information. You need to visit the SenseTime Seko platform to obtain the detailed pricing plan.

• 5. User reviews (1112 chars)

  positive feedback   Users generally speak highly of SekoTalk's efficiency improvements. Feedback from professional animators: “In the past, 70% of the time was spent on technical adjustments, but now it’s the other way around, 70% of the time is spent on creativity.” An independent creator said, "In the past, you had to manually adjust lip sync, but now you can do it in a few minutes, and the efficiency is increased by 10 times."   The core reasons why users choose this product are "zero learning curve" and "full-process integration with the Seko platform." Compared with competing products, SekoTalk performs outstandingly in multi-person scene processing and long video stability. Agency verification data shows that the character consistency in the 10-minute short drama reaches 98%, the sub-shot adjustment time is shortened from 2 hours to 5 minutes, and the plot coherence is increased by 300%.   negative feedback   The 60-second limit on the free version is an inconvenience for users with long video needs. Extremely high-speed rapping or exaggerated facial expressions may produce slight mouth shape deviations. There is still room for improvement in rendering complex facial expressions. Maximum accuracy is for medium-paced everyday conversations, minor deviations may occur for extreme vocal styles.

• 6. Industry evaluation (632 chars)

  SekoTalk's technological breakthrough has received positive attention from industry media. The review article pointed out that SekoTalk solved the core bottleneck of AI video lip-syncing technology - the problem of multi-person scenes. Through the Canvas editing function, users can modify specific picture elements without affecting the overall composition.   Since its launch, the product has helped users create hundreds of thousands of works, and produced popular videos that have been viewed more than 20 million times online. The technical team proposed Phased DMD (phased distribution matching distillation) technology to solve the problem of reduced motion effects and instruction following ability during the denoising process.

• 7. Controversies and Risks (289 chars)

  No major controversies or risk events regarding SekoTalk have been found in public information. As a compliance product of SenseTime, we need to pay attention to the security and compliance issues of AI-generated content, especially at the application boundaries of sensitive scenarios such as commercial advertising and news broadcasts.

• 8. Applicable groups and usage suggestions (983 chars)

  Who it’s suitable for: Content creators who need to produce digital human broadcast videos; MCN organizations and short drama creators who need multi-person dialogue scenes; e-commerce practitioners who want to quickly generate lip-sync videos; professional users who require the stability of long videos.   Who it is not suitable for: Detailed production scenes that require extremely high hand animation quality; professional music videos that require perfect reproduction of extreme vocal styles; users with limited budgets who only need short-term audio (consider the free version to experience).   Alternatives: Overseas digital human platforms such as HeyGen and D-ID; lip synchronization functions of AI video generation tools such as Runway and Pika.   Usage recommendations: It is recommended to start with the 60-second free version to experience it, and then upgrade to the paid version after verifying the lip synchronization effect. Prepare clear, front-facing images of your characters for best results. Be as specific as possible when using natural language to describe actions, which helps the system understand the intent more accurately.

  跟 HeyGen 对比了一下，SekoTalk 在中文口型匹配上更准，但是 HeyGen 的虚拟人形象更丰富，各有优势吧。
