Hume AIとは何ですか?
Hume AI is an emotion recognition platform designed to analyze human emotions.
It reads human emotion through voice facial expressions and text signals.
Dr. Alan Cowen founded it and still leads the company.
The CEO of Hume AI is a cognitive scientist who studies emotion.
This is not the first emotional AI, but the models go deeper than most.
The Empathetic Voice Interface is built to read and respond to human emotions.
EVI 3 shipped in 2025 with ultra-low latency and personality mimicry.
で 早い 2026, Google DeepMind licensed that emotional layer for its own models.
This video walks through the interface and the voice demos.
Runner Up: Hume AI
Build voice agents that hear feeling, not just words. Start on the free tier of Hume AI and explore Octave TTS before you spend anything.
Hume AIの価格
Seven tiers, scaling from hobby projects to full deployments.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | $0 | APIのテスト |
| スターター | $3 | ソロ 建設業者 |
| クリエイター | $14 | Small voice projects |
| プロ | $70 | 生産アプリケーション |
| 規模 | $200 | チームの成長 |
| 仕事 | $500 | High-volume products |
| 企業 | 営業担当者へのお問い合わせ | カスタムデプロイメント |
Pricing verified September 2026.
Above the free tier, usage is pay as you go against your plan credits.
無料トライアル: No timed trial. The Free plan stays open with capped usage and no card required.
返金保証: None published. Credits are consumed as you call the API.
📌 注記： Plan price is a floor, not a ceiling. Heavy API traffic adds overage on top. Our Hume AI review breaks down the credit math.
⚠️ 警告： Costs climb fast once traffic grows. Model your monthly call volume before moving off Creator.
Hume AIの主な利点
Here is what developers actually buy it for:
- Multimodal emotion recognition: Hume’s AI algorithms use voice video and text data during training. Nothing gets scored on words alone.
- 表現測定API： It rates audio and emotional indicators like smiling frowning and eyebrow movements in video across a wide range of emotions.
- Live coaching: The emotion recognition technology provides insights agents can act on mid-conversation.
- Octave TTS: Voices are generated with emotions and speaking styles inferred from the script itself.
- Broad fit: Teams deploy it across industries including customer service healthcare and market research.
- Custom personas: TTS Creator Studio shapes voice character for personalized and empathetic interactions.
Each endpoint is documented separately, so start with one before wiring the rest.

機能比較
Ten rounds, scored on what each platform is actually built to do.
| 特徴 | スピーチファイ | ヒュームAI |
|---|---|---|
| Starting paid price | 月額11.58ドル | $3 |
| 無料プラン | ✅ | ✅ |
| Reads your own documents | ✅ | ❌ |
| OCR for printed pages | ✅ | ❌ |
| 感情検出 | ❌ | ✅ |
| Facial expression analysis | ❌ | ✅ |
| モバイルアプリ | ✅ | ❌ |
| 開発者API | ✅ | ✅ |
| 最適な用途 | テキストを聞く | Building emotional AI |
1. AI音声と音声品質
スピーチファイ： The library holds more than 1,000 AI voices, including celebrity licences. Paid tiers deliver high quality voices with adjustable pitch, while the free version sticks to non HD voices that sound noticeably flatter.
ヒュームAI: Octave TTS reads the meaning of a script before speaking it. That produces human like voices that sigh, hesitate, and lift at the right moment.
2. 感情的知性
スピーチファイ： There is none, and that is by design. It narrates written text cleanly but ignores user emotions completely.
ヒュームAI: Its emotion recognition algorithms interpret subtle cues in speech and expression. Hume AI can analyze a customer’s tone of voice during a support call or detect emotional shifts inside a chat thread.
⚠️ 警告： Emotional responses are inferred, not certain. Treat every score as a signal to check, never as a verdict about a person.
3. Reading Printed Text and OCR
スピーチファイ： Scan a page and the app’s ability to handle both handwritten and typed text shows up fast. Speechify reads receipts, textbooks, and worksheets aloud within seconds, allowing users to listen to anything on paper.
ヒュームAI: No scanning, no camera capture, no document reader. You feed it text or audio through code and nothing else.
4. Voice Cloning and Custom Personas
スピーチファイ： Voice cloning builds a copy from a short sample. Record somewhere quiet, because background noise in the source clip carries straight into the clone.
ヒュームAI: TTS Creator Studio shapes a persona from a written description instead of a recording. You tune warmth, pace, and character rather than copying a voice.
5. Languages and Dubbing
スピーチファイ： Over 60 languages are covered, and AI Dubbing swaps a video track into another tongue. That range makes it a versatile tool for teams publishing in multiple languages.
ヒュームAI: Coverage is thinner. The platform primarily supports English, so non-English products hit a wall early.
6. Developer Access and APIs
スピーチファイ： API access exists for converting text into audio at volume. It is a narrow endpoint, useful for publishers generating audio files in bulk.
ヒュームAI: The API is the product. The Expression Measurement API lets developers track emotion trends across user data over time.
7. Conversation and Assistant Features
スピーチファイ： AI summarization trims long reports, and the roadmap points at a Voice AIアシスタント. Today it still answers to you, not with you.
ヒュームAI: Conversational Voice holds a live two-way exchange and adjusts tone mid-sentence. Studios use Hume AI to detect frustration in players and change how characters reply.
8. Platforms and Apps
スピーチファイ： iOS, an Android app, desktop, and a Chrome extension all sync one queue. Offline downloads keep the listening experience going on a plane.
ヒュームAI: There is a web console and SDKs, and that is the whole surface. No consumer app ships with it.
9. 使いやすさ
スピーチファイ： Simply upload a file, paste a link, or import text and press play. Speechify lets you skip setup entirely, which is why it works as a popular app for non-technical readers.
ヒュームAI: Expect a steep learning curve. Reading the docs, wiring a key, and handling streams comes before your first result.
10. 価格設定とコスト
The plans sit side by side below.
| ティア | スピーチファイ | ヒュームAI |
|---|---|---|
| 無料 | 制限あり：月額0ドル | 無料：0ドル |
| 入場料支払い済み | 年間：月額11.58ドル | Starter: $3 |
| 中 | 月額料金：29ドル/月 | Creator: $14 / Pro: $70 |
| 大量 | ❌ | Scale: $200 / Business: $500 |
| カスタム | ❌ | 法人向け：営業担当までお問い合わせください |
スピーチファイ： One person, one flat fee, unlimited listening inside the word cap. Paying annually cuts the monthly figure by roughly 60 percent, and the price is the same whether you read ten pages or a thousand.
ヒュームAI: Three dollars gets you in, but the bill tracks usage from there. Budget by call volume, not by seat, and watch the jump from Pro to Scale.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |

💰 あなたの予算
Hume AI opens lower at $3, but that number moves with usage. Speechify offers a fixed annual rate that never surprises you.
🔌 あなたの技術スタック
If your stack is a browser and a phone, pick Speechify. If it includes a codebase and a deploy pipeline, Hume AI fits.
📝 あなたの読書スタイル
Skimmers gain the most from a faster reading experience with highlighting on. Deep readers often drop the speed and treat it as an audiobook.
🎓 あなたの経験レベル
Speechify users need no technical background at all. Hume AI expects comfort with keys, endpoints, and streaming audio.
🆓 無料トライアルとデモ
Start on the basic version of each before paying anything. Three days on Speechify premium is enough to test the key features you care about.
🛟 サポートオプション
Speechify runs help centre and email support for consumers. Hume AI leans on documentation, a developer community, and sales contact at the top tier.

私たちのレビューで取り上げられなかったこと
We focused on individual readers and small development teams. We did not benchmark latency under load, test enterprise contracts, or measure emotion accuracy against a clinical baseline. Text editing workflows inside other apps sit outside this comparison too. Prices and plan names reflect September 2026, and both products ship changes often.

🏆 受賞者：SPEEPHIFY
Speechify wins 4 of 7 categories.
最適な用途: Students, commuters, and anyone with reading difficulties who wants to convert text into audio today.
Both products score 4.2 in our database, so this was a tie on paper. We broke it on audience fit: far more people arrive here wanting something to read their PDFs than wanting to ship a voice agent.
Speechify stands closer to a finished product. It is a valuable tool for anyone whose reading pile keeps growing, and it enhances productivity from the first day without a single line of code.
Hume AI is a new AI with emotional intelligence at its centre, and a powerful tool in the right hands. As a popular emotion recognition platform it belongs in products that need to understand people, not just talk at them.
Pick Speechify to enhance productivity as a reader. Pick Hume AI when your software has to listen back.
