# Unique Research | Deep Dive: Five Mainstream AI Digital-Human Products Compared

_Unique Research · Product review · July 5, 2024_

AI digital humans combine simulation and AI for human-like looks and multimodal interaction — customer service, education, entertainment, and more. With many products on the market, Unique Research compares five mainstream platforms: **HeyGen**, **SenseTime SenseAvatar (如影)**, **Tencent ZenVideo (智影)**, **Silicon-based Silicon Speech (硅基硅语)**, and **Xmov Youyan (魔珐有言)**.

## Market & tech backdrop

iiMedia’s _2024 China Virtual Digital Human Industry White Paper_: 2023 China virtual-human **core** market **¥20.52B**, expected **¥48.06B** by 2025; industry-driven market **¥333.47B** (2023) → **¥640.27B** (2025). Domestic stacks lean on NLP, multimodal fusion (voice/gesture/touch/gaze), and XR (AR/VR/MR). Strong scenes: 24/7 livestream, education, culture-tourism guides/museums, professional services (law, insurance, government). GenAI helps interaction quality, but answer latency still lags real-time dialogue needs — a model problem to solve. Near-term interaction leaps expected in games (NPC voice/text), livestream commerce, and functional roles (AI teachers, AI broker analysts). Rendering quality and brand-fit avatars remain commercialization gates.

## 1\. HeyGen

Pro AI digital-human video platform: upload video → extract face/expression → avatar for hosting, support, etc. Flow: register, upload expressive face video, templates or custom; adjust size/position, voice, script, stickers/music. Voice clone (many languages; Chinese pronunciation still improving). Lab features (e.g. video translation). Pricing: monthly/annual tiers for individuals, teams, enterprises; new-user free trial time. Broad use: social, ads, education, news, CS, brand, entertainment, virtual livestream, endorsements.

## 2\. SenseTime SenseAvatar (如影)

On SenseNova (“日日新”): text/speech/motion/image generation, NeRF; lip sync, expression, motion. Create video from text or PPT + avatar + voice; online edit background/PiP/text. Personal 2D avatar in ~**5 minutes** (1080P/2K/4K). Voice clone from little audio via transfer learning; multilingual. Template marketplace. Pricing: VIP tiers, custom training fees, add-on packs. Strong in short video, livestream, education, finance.

## 3\. Tencent ZenVideo (智影)

Site: https://zenvideo.qq.com — end-to-end online edit (assets → cut → package → render → publish). Digital-human broadcast (horizontal/vertical templates, PPT import, backgrounds, Tencent Video assets, AI rewrite/expand/shrink); text-to-speech with fine pronunciation controls; article-to-video (Tencent Video licensed assets, auth required); avatar + voice custom (photo face-swap, voice clone); livestream (trial + pro with human takeover; interactive Q&A library). Pricing: custom + membership; livestream billed extra. Scenes: production, education, entertainment, news, social, livestream.

## 4\. Silicon-based Silicon Speech (硅基智能 / 硅基硅语)

Since 2018: first commercial AIGC digital human claimed; ~**500,000** cloned avatars; ~**50,000** digital-human livestreams/day; valuation near **$1B**; ~100 patents. Custom avatar from 2–3 min script video; voice clone from corpus or online record; one-click video translation keeping timbre/style; talking photos; marketplace of models/templates/voices. Pricing in “diamonds” (¥1 = 1 diamond): e.g. general video 5/min; audio 1/min; talking photo 5/min; avatar clone S ultra-HD 8,000; livestream advanced scene clone 20,000; online record 8,000; clone E/S 980/3,980; voice clone E/S 680/3,980. Fits banking, finance, knowledge paid, science education.

## 5\. Xmov Youyan (魔珐有言)

Site: https://youyan.xyz/platform/home/prime?from=xmovai — one-stop AIGC video: text→3D video, text→3D shots (pan/full/mid/close/CU), text→script, etc. Strong 3D naturalness; less emphasis on ultra-fast custom. Flexible monthly/annual plans. Scenes: 3D video, ads, social, education, corporate.

## Five-way comparison

**Voice diversity & custom:** HeyGen leads (~300 voices, 50+ languages, tight lip-sync; Chinese still improving). SenseAvatar/Youyan more limited voices/custom; ZenVideo mainly CN/EN; Silicon-based stronger voice taxonomy.

**Avatar & motion naturalness:** HeyGen fluent body/lip + rich custom; SenseAvatar/ZenVideo more limited (SenseAvatar has 3D but scarce assets); Silicon-based average; Youyan stands out on 3D naturalness but lacks fast custom.

**Production tools:** HeyGen mature AI fusion; SenseAvatar covers basics (AI copy needs work); ZenVideo strong AI rewrite tools + film library + smart erase/captions; Silicon-based friendly editor (weaker AI text gen); Youyan strong 3D tooling.

**Pick by scene** — HeyGen for global multi-use; SenseAvatar short video/live/edu/finance; ZenVideo China content stack; Silicon-based pro finance/edu; Youyan 3D-first creatives.
