コロサイとは何ですか？
Colossyan is an AI video generator built for training teams.
You paste a script and it returns a finished video.
A digital presenter reads your written text on screen.
Colossyan offers over 200 diverse AI avatars for conversational scenarios.
Its speech technology covers over 70 languages and accents.
That mix suits corporate training, explainer videos, and marketing videos.
Here is a walkthrough of how the editor works.
🏆 Winner: Colossyan
Turn a script into a finished video with talking avatars. Export straight to your Learning Management System.
コロシアンの価格
Colossyan runs on three tiers. There is no free plan.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| スターター | 月額19ドル | Solo creators making short explainer videos |
| 仕事 | 月額70ドル | L&D teams needing branching and analytics |
| 企業 | カスタム | Large organisations with 安全 レビュー |
Pricing verified August 2026.
無料トライアル: Yes. You can create a test video before paying, though exports on the trial carry limits.
返金保証: No public refund window. Cancel before renewal to avoid the next charge.
📌 注記： Video minutes are the real cost driver here, not seats. Check your monthly minute allowance before you commit to a plan.
⚠️ 警告： SCORM export and branching sit on the higher tier. Starter is fine for simple videos, but not for Learning Management System delivery.
Colossyanの主な利点
Here is what makes this AI tool worth a look:
- Script to video: Paste a draft and get professional videos back. The production process drops from days to minutes.
- 話すアバター： Over 200 AI avatars can hold two-person conversations on screen. That helps role-play training.
- Voice coverage: Natural sounding voiceovers in over 70 languages and accents reach a global audience.
- SCORM packaging: Colossyan supports SCORM 1.2 and 2004, so audio-visual training drops into an LMS.
- Document to video: Upload a PDF or slide deck and turn it into video content with a presenter.
- 組み込み分析: You see who watched and where they dropped off. Most AI video tools skip this.

- Over 200 voices in more than 30 languages
- Reads documents, emails, and web articles through one interface

- No SCORM export, so training teams still need another tool
機能比較
Both tools convert written text into speech. Both lean on machine learning algorithms and natural language processing to shape human speech patterns.
The AI technology underneath is similar. The output is not. Here are ten areas that decide which one belongs in your workflow.
| 特徴 | コロサイ | スピーチファイ |
|---|---|---|
| 開始価格 | 月額19ドル | 月額0ドル |
| 無料プラン | ❌ | ✅ |
| Video Output | ✅ | ❌ |
| AIアバター | ✅ 200以上 | ❌ |
| 音声カウント | 70以上の言語 | 200+ voices, 30+ languages |
| 音声クローン | ❌ | ✅ |
| SCORMエクスポート | ✅ | ❌ |
| ブラウザ拡張機能 | ❌ | ✅ |
| 分析 | ✅ | ❌ |
| 最適な用途 | AI video and training | Reading and voiceovers |
1. Video Creation and Output
コロシアン： Script to Video is the core of the tool. You drop in a script and the video generator builds scenes, timing, and a presenter. Document-to-video conversion also turns slide decks into video in just a few clicks.
スピーチファイ： There is no video creation here at all. Speechify Studio produces an audio track that you drop into an editor yourself. For anyone whose end goal is finished video content, that is an extra step every time.
2. AI Avatars and Talking Presenters
コロシアン： Over 200 diverse AI avatars are available, and two can share a scene. Those conversational setups are the most impressive features in the editor, especially for compliance or sales role-play.
スピーチファイ： No talking avatars exist in the product. You get a voice and nothing on screen. If a face matters to your audience, this is a hard stop.
3. AI音声と音声品質
コロシアン： Its speech synthesis generates natural sounding voiceovers in over 70 languages and accents. The AI voices are tuned for narration, so you get engaging voiceovers that read steadily rather than dramatically. That fits training more than storytelling.
スピーチファイ： The TTS voices lean warmer and carry more range. Over 200 options cover plain readers through to expressive voices, and you can fine tune speed and pitch. On raw voice quality, this side wins.
⚠️ 警告： Neither tool matches professional voice actors on emotional delivery. Synthetic voices still flatten sarcasm, grief, and jokes that real human voices carry without effort.
4. 音声クローン
スピーチファイ： Voice cloning is built in. You record a sample and the machine learning model rebuilds it as a reusable voice. Teams use it to keep one narrator across a whole course.
コロシアン： Cloning is not a headline feature. You pick from the stock voice library instead. For most L&D work that is fine, but it removes one route to a branded sound.
5. Multilingual Support and Dubbing
スピーチファイ： AI Dubbing rewrites an existing track into another language. Multilingual support spans more than 30 languages, which covers most consumer markets but not every regional accent.
コロシアン： Over 70 languages and accents means one script can ship to multiple languages without rebuilding the video. For a global audience with regional offices, that gap matters more than voice warmth.
6. Backgrounds, Background Music, and Transitions
コロシアン： Dynamic backgrounds swap the scene behind your presenter without a green screen.
You can also upload your own background music and set it under the narration.
Scene changes are handled by preset transitions rather than a manual timeline.
スピーチファイ： None of this exists, because there is no canvas to design. You export audio and add music in your own editor. That suits creators who already run Premiere or 説明.
7. Interactive Training and Branching Scenarios
コロシアン： Branching scenarios let a viewer pick an option and follow a different path. Paired with SCORM 1.2 and 2004 export, that turns a video into trackable coursework inside a Learning Management System.
スピーチファイ： Playback is linear. It reads educational materials aloud well, but it cannot ask a 質問 or record an answer. Course completion tracking has to live somewhere else.
8. Reading Experience and Accessibility
スピーチファイ： Scan and Listen reads printed pages through your phone camera. Highlighting, note-taking, and a user friendly interface make it a valuable tool for dyslexic and ADHD readers. These are the standout features of the whole app. This is the strongest part of the product.
コロシアン： Accessibility here means キャプション and multiple languages on finished videos. It was never designed to read your 受信トレイ, so daily consumption is not its job.
9. Screen Recording, Analytics, and API Access
コロシアン： A built-in screen recorder captures software walkthroughs without a second app. It enables users to record and narrate in one sitting.
Video analytics then show completion rates for every published piece.
スピーチファイ： API access is the developer route into its speech engine. If you want voice generation inside your own app, that hook exists here and not on the Colossyan side.
10. 価格設定とコスト
Here are the plans side by side.
| ティア | コロサイ | スピーチファイ |
|---|---|---|
| 無料 | ❌ | 制限あり：月額0ドル |
| エントリ | スタータープラン：月額19ドル | 年間：月額11.58ドル |
| 中 | ビジネス：月額70ドル | 月額料金：29ドル/月 |
| トップ | エンタープライズ：カスタム | ❌ |
コロシアン： Starter at $19/month is competitive pricing for an AI video generator, since agency video costs far more per minute. Business at $70/month is where branching and analytics live, and that is the tier most training teams end up on.
スピーチファイ： The free Limited plan is a real entry point, not a demo. Annual works out at $11.58/month, while month-to-month costs $29. That gap is the widest annual discount in this comparison.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Finished video files | コロサイ | Only tool that renders video |
| To listen while commuting | スピーチファイ | Mobile and browser playback |
| LMS-ready training | コロサイ | SCORM 1.2および2004エクスポート |
| A cloned narrator voice | スピーチファイ | Voice cloning on paid tiers |
| Zero upfront spend | スピーチファイ | Free Limited plan |
| Role-play scenarios | コロサイ | Two avatars per scene |
💰 あなたの予算
Speechify wins on entry cost with a free tier and $11.58/month annual billing. Colossyan starts at $19/month, which is still cheap against hiring professional voice actors and a camera crew.
🔌 あなたの技術スタック
If your team already runs an LMS, Colossyan drops straight in through SCORM. If you are building software, Speechify’s API lets you generate speech inside your own product.
📝 Your Output Type
Ask what you hand over at the end. A video file points to Colossyan, while an audio track or a spoken article points to Speechify.
🎓 あなたの経験レベル
Speechify has the gentler learning curve because listening needs no setup. Colossyan asks you to think in scenes, though its editor is still friendlier than traditional video software.
🆓 無料トライアルとデモ
Test both with your own script rather than the sample text. Sample copy is chosen to flatter the voice engine, and real content exposes odd pronunciation fast.
🛟 サポートオプション
Colossyan leans on account support for business plans, which suits rollout questions. Speechify runs mostly on help-centre articles and email, so answers take longer.

私たちのレビューで取り上げられなかったこと
We looked at everyday content creation for small teams and solo creators. We did not measure rendering speed at scale, test enterprise SSO, or price custom Colossyan contracts. Voice output quality was judged by ear, not by a lab test of speech synthesis accuracy. If you publish in low-resource languages, your results will differ from ours.

最適な用途: Corporate training, explainer videos, multilingual product walkthroughs
Colossyan takes it because the searches behind this comparison are about video, and it is the only one of the two that makes video. Its advanced AI handles avatars, scenes, and narration in one pass.
Speechify is not the weaker product. It is a different product. For reading, studying, and creating voiceovers on a budget, it is the better buy and the free plan proves it.
Pick Colossyan when the deliverable is a video. Pick Speechify when the deliverable is audio or when you simply want your reading list read aloud.

No. The Limited plan costs $0/month with standard voices. Paid access runs $11.58/month annually or $29/month, which unlocks the full library and offline listening.
あなたは Speechifyを使用する 商用利用ですか？
Commercial rights come with Studio plans, not the free reader. Check the licence terms before publishing professional voiceovers, since rules differ by voice.
