⚡ 快速结论:
- 定价: Synthesia starts at $18/month. Synthesys starts at $20/month.
- 最适合: Synthesia for training and localised video creation. Synthesys for voice generation and talking photos.
- 主要区别: Synthesia ships an AI screen recorder and interactive videos. Synthesys does not.
- 我们的选择: Synthesia (4.6) for most teams, based on its wider feature set and 140+ language support.

Two products, one letter apart, and very different jobs.
Synthesia started as an ai video creation platform for corporate training.
Synthesys started as a voice generation engine and grew outward from there.
That history still shapes what each one does well today.
Here is how the two compare on price, features, and fit.

The rest draws on published specs, documentation, and G2 reviews.
By the end you will know which tool fits your workflow.
Synthesia是什么?
Synthesia is an ai video creation platform built around ai avatars.
You type a script and pick a presenter.
The system renders a finished clip without a camera or studio.
Its avatars carry the most natural facial expressions and gestures in this category.
You can import PowerPoint 演示文稿 and turn slides into narrated video.
Teams mostly use it for onboarding, product walkthroughs, and internal training.

The walkthrough below shows the editor and avatar library in action.

🏆 Winner: Synthesia
Script-to-video in a few minutes, with no filming. Supports 140+ languages for a broader audience. Built for teams that publish training video at volume.
Synthesia 定价
Synthesia runs on three tiers. Here is the breakdown.
| 计划 | 价格 | 最适合 |
|---|---|---|
| 起动机 | 每月18美元 | 单人创作者测试人工智能视频 |
| 创作者 | 每月 64 美元 | Marketing teams publishing weekly |
| 企业 | 定制定价 | Mid-to-large firms needing SOC 2 and LMS delivery |
Pricing verified August 2026.

免费试用: Yes. A free demo video lets you test the editor before paying.
退款保证: No published refund window. Cancel before renewal to avoid the next charge.
📌 笔记: Plans are metered by video minutes, not by seats alone. Heavy publishers hit minute caps before they hit user caps.
⚠️ Pricing conflict: Some third-party trackers list Synthesia at $29/month and Synthesys at $23/month. Our CSV records $18/month and $20/month. We publish the CSV figures and flag the gap rather than pick silently. Check the vendor page before you buy.
Synthesia 的主要优势
Here is what makes Synthesia worth a look:
- Language reach: Over 140 languages are supported. That matters if you localise for a broader audience.
- 1-click translation: A finished video can be re-voiced without a separate translation project. 唇语同步 follows the new track.
- Security posture: SOC 2 Type II compliance is in place. Mid-to-large firms usually require this before rollout.
- LMS delivery: Videos push into Learning Management Systems. Training teams skip manual re-uploads and save time.
- 屏幕录制: Capture your screen inside the same tool. Software demos stay in one place.
- Interactive video: Add clickable elements to a finished clip. Useful for quizzes and branching training.
- 模板库: Editable templates cut setup work. You adjust rather than build from a blank canvas.

Synthesia 的优点和缺点
✅ 优点
- Avatars show the most natural facial expressions in this category
- Over 140 languages supported for global teams
- SOC 2 Type II compliance suits mid-to-large businesses
- Screen recorder and interactive videos are built in
- PowerPoint presentations convert into narrated video
❌缺点
- The jump from Starter to Creator is a large price step
- Video minutes are capped on every paid tier
- Timeline control is thinner than a traditional video editor
- Enterprise pricing is quote-only, so budgeting takes a sales call
Synthesys是什么?
Synthesys is an artificial intelligence studio for voice and video.
Voice generation came first, and it is still the strongest part.
The library holds over 400 voices for cloning and specific tones.
AI Humans then puts those voices on screen with a presenter.
AI Talking Photos animates uploaded photos into short speaking clips.
Small teams use it to create content for ads and social posts.

This walkthrough covers the voice library and the video side together.

亚军:Synthesys
Over 400 voices, plus gesture control for avatar motion. Talking Photos animate stills you already own. A fit for ad creative rather than long training.
Synthesys定价
Synthesys also runs three tiers, with no custom quote at the top.
| 计划 | 价格 | 最适合 |
|---|---|---|
| 个人的 | 每月 20 美元 | Solo creators doing voiceover work |
| 创作者 | 每月 41 美元 | 自由职业者 mixing voice and ai video |
| 商业 | 每月 69 美元 | Small teams shipping ad creative |
Pricing verified August 2026.

免费试用: A limited free tier lets you test voices before you commit.
退款保证: No blanket refund policy is published. Cancellation is handled from account settings.
📌 笔记: The top Business tier costs $69/month, which still lands under Synthesia’s $64 Creator plan plus any overage. Compare by output volume, not headline price.
⚠️ 警告: G2 reviews flag subscription cancellation as a recurring friction point. Cancel from the dashboard and keep the confirmation email.
Synthesys 的主要优势
Here is where Synthesys earns its place:
- Voice depth: Over 400 voices cover cloning and specific tones. That is the deepest part of the product.
- Gesture control: Dynamic gesture control fine-tunes how an avatar moves. You get more dynamic results than a static presenter.
- 会说话的照片: Still images become speaking clips. Useful when you have hd photos but no footage.
- Face form: Customization features let you adjust facial detail on a presenter.
- Synthesys 实验室: A sandbox for testing output before you spend credits on a full render.
- 音频翻译: Voice tracks convert across multiple languages without re-recording.

- Cancellation draws repeated complaints in reviews
功能对比
Both tools turn text into video. The difference shows up once you look at what surrounds that core step.
Here are ten areas that decide the Synthesia vs Synthesys 问题 for most buyers.
| 特征 | Synthesia | Synthesys |
|---|---|---|
| 起价 | 每月18美元 | 每月 20 美元 |
| AI化身 | ✅ | ✅ |
| Voice Cloning Library | ✅ | ✅ 400+ voices |
| 屏幕录制 | ✅ | ❌ |
| 互动视频 | ✅ | ❌ |
| 会说话的照片 | ❌ | ✅ |
| Gesture Control | ❌ | ✅ |
| SOC 2 II 型 | ✅ | ❌ |
| 语言支持 | 140+ | 多语言 |
| 最适合 | Training and localisation | Voiceover and ad creative |
1. 人工智能化身
Synthesia: The avatar library is the reason most buyers land here. Mouth shapes and facial expressions hold up on close crops, which is where cheaper tools break. You can also create custom models of a real presenter on higher tiers.

Synthesys: AI Humans covers the same ground with a smaller cast. Gesture control is the trade: you can fine-tune how a presenter moves, which gives more dynamic results in short ads. Close-up realism still trails Synthesia.

2. 语音生成
Synthesia: Text-to-speech is tied tightly to the avatar. Delivery is even and clear, which suits training narration. Fine tonal control is thinner than a dedicated voice tool.

Synthesys: This is the strongest column on the page. A library of 400+ voices covers cloning and specific tones, so you can match a brand voice instead of settling. If voice generation is the deliverable, Synthesys wins outright.

3. 模板和自定义
Synthesia: Editable templates cover onboarding, product updates, and policy briefs. Brand kits lock fonts and colours across a team. You adjust a starting point rather than building each video creation job from zero.

Synthesys: Generate AI Media handles images and clips inside the same workspace. Customization features lean toward creative assets rather than corporate layout. Fewer ready-made structures means more manual setup.

4. 视频编辑器
Synthesia: The video editor is scene-based rather than timeline-based. Edits are quick, and a script change re-renders in a few seconds on short clips. Anyone expecting frame-level video editing tools will find it limited.

Synthesys: Text-to-video generation follows the same script-first pattern. Assembly is straightforward, though the editor gives you less layout control across longer sequences.

💡 专业提示: Neither tool replaces Premiere or Final Cut. Draft the ai video here, then finish colour and pacing elsewhere if the project demands it.
5. 协作与共享
Synthesia: Comments, shared workspaces, and reviewer links are standard. Videos can push into a Learning Management System, so training reaches staff without a manual upload step.

Synthesys: Synthesys Lab acts as a testing sandbox before a full render. Team review is lighter, which suits a solo creator more than a ten-person department.

6. AI Assistant and Scripting
Synthesia: The AI Video Assistant drafts a script and scene order from a prompt or a document. It handles the blank-page problem, which is where most teams stall.

Synthesys: Face form focuses on presenter detail rather than scripting. You bring the copy yourself, then tune how the face and delivery look.

7. Screen Recording and Talking Photos
Synthesia: The AI Screen Recorder captures your screen next to an avatar. Software demos and support walkthroughs stay in one tool instead of two.

Synthesys: AI Talking Photos animates uploaded photos into speaking clips. Add more photos and you have a small cast without a shoot. There is no screen capture at all, which rules it out for product demos.

8. Translation and Language Support
Synthesia: Support runs past 140 languages, and 1-click translation re-voices a finished video. A localisation run that once needed a whole translation project now takes one pass.

Synthesys: Audio translations convert a voice track across multiple languages without re-recording. Coverage is narrower, so check your target list before committing.

9. Reach and Distribution
Synthesia: Interactive videos add clickable steps and quiz points inside a clip. For onboarding, that turns passive viewing into something you can measure.

Synthesys: Multilingual support is the main reach lever here. It helps you serve a broader audience, but there is no interactive layer on top.

10. 定价与成本
Entry prices sit within $2 of each other. The gap opens at the middle tier.
| 层级 | Synthesia | Synthesys |
|---|---|---|
| 入口 | 入门级——每月 18 美元 | 个人版——每月 20 美元 |
| 中 | 创作者 — 每月 64 美元 | 创作者 — 每月 41 美元 |
| 顶部 | 企业版 — 定制定价 | 商务版——每月 69 美元 |
Synthesia: The $18 Starter is the cheapest door on this page. The $64 Creator plan is where the cost sits for real output, and Enterprise is quote-only. You pay more for compliance, language reach, and the screen recorder.
Synthesys: At $41/month the mid tier undercuts Synthesia’s Creator plan by $23. The $69 Business plan is a fixed number, so a small team can budget without a sales call.
不同场景
| 如果您需要…… | 选择 | 为什么 |
|---|---|---|
| Corporate training video | Synthesia | LMS delivery and SOC 2 |
| Brand-matched voiceover | Synthesys | 400+ voices for cloning |
| Software demos | Synthesia | 内置屏幕录制器 |
| Animated stills | Synthesys | Talking Photos from images |
| Wide localisation | Synthesia | 支持 140 多种语言,一键翻译 |
| Fixed mid-tier budget | Synthesys | 每月 41 美元 vs 每月 64 美元 |
💰 您的预算
Entry tiers are nearly identical at $18 and $20. The real question is the middle tier, where Synthesys costs $41 against Synthesia’s $64.
🔌 您的技术栈
Video tools are usually judged on how well they slot into the software you already run. Synthesia pushes into an LMS; Synthesys sits closer to your design and ad tools.
🎬 Your Output Type
Long explainers and policy videos favour Synthesia. Fifteen-second ad cuts and voice-led social clips favour Synthesys.
🎓您的经验水平
Neither tool needs editing skills, which is the point of ai video. Both let a beginner ship something watchable on day one and save time on filming.
🆓 免费试用和演示
Some platforms in this category start at $0 and charge per use instead of monthly. Test a real script on both before you pick a plan.
🛟 Support and Compliance
Synthesia meets the security bar that mid-to-large firms ask for before rollout. Synthesys has no equivalent published certification.

我们的评测没有涵盖的内容
This comparison focused on individual creators and small-to-mid teams. We did not test enterprise SSO, API access, or bulk seat licensing on either platform. Render speed varies with clip length and server load, so we avoid quoting fixed numbers. If you publish hundreds of videos a month, your cost per minute matters more than the headline plan price.

🏆 获奖者:SYNTHESIA
Synthesia wins 5 of 7 categories.
最适合: employee training, localised product video, software demos, teams that need SOC 2
These two products are not really chasing the same buyer. Synthesia is a training and localisation engine. Synthesys is a voice studio that also makes video.
Synthesys is the better pick when the audio track is the product. The voice library is deeper, the mid tier costs $23 less, and gesture control adds motion that short ads benefit from.
For everything else, Synthesia takes it. Wider language support, a built-in screen recorder, interactive video, and a security posture that passes procurement. Both cut filming out of the process, which is the real saving either way.

常见问题解答
有没有比 Synthesia 更好的软件?
It depends on the job. HeyGen suits fast social clips, Colossyan suits branching training, and Synthesys suits voice-led work. For broad corporate video, none clearly beat it.
Synthesia 完全免费吗?
No. A free demo video lets you test the editor, but continued use needs a paid plan. Pricing starts at $18/month on the Starter tier.
Synthesia付费版和免费版有什么区别?
The free demo is a one-off preview with heavy limits. Paid plans unlock video minutes, the full avatar library, translation, and export without a watermark.
HeyGen和Synthesia有什么区别?
HeyGen leans toward quick avatar cloning and short social video. Synthesia leans toward training, 140+ languages, screen recording, and the compliance larger firms require.
What Synthesia can do?
It turns a script or slide deck into narrated video with an 人工智能化身, records your screen, translates finished clips, and pushes output into a learning system.
