Speechifyとは何ですか?
Speechify is a text to speech app that turns written text into spoken words.
It reads books, emails, PDF documents and web pages out loud.
You can convert text from a file, a link, or a photo of a page.
The founder built the first version to work around his own dyslexia.
That origin story still shapes the product today.
Speechify now helps tens of thousands of people with dyslexia, ADHD, low visual acuity and concussions.
The Speechify app runs on iOS, on an Android app, and as a Chrome extension.
The walkthrough below shows the reading interface in action.

Speechifyの主なメリット
Speechifyが注目に値する理由は以下のとおりです。
- Fast reading speed: Speed and voice controls shape the listening experience, and you can push playback up to 900 words per minute. The average reading speed for adults sits near 250, so you save time on long documents.
- OCR reader built in: Optical character recognition pulls printed text off photos. Snap a page from physical books and Speechify reads it back.
- Live text highlighting: Words light up in sync with the audio, allowing users to follow along. Academic research links hearing and reading together to better comprehension.
- Offline listening: Downloaded items keep working without signal. Hands-free playback on a commute enhances productivity across the week.
- 多言語対応: Support spans 60+ different languages. Language learners can hear the same passage in a different language.
- Flexible import: You can simply upload a file, paste a link, or import text by copy and paste.
- Study tools: On-repeat playback and note extraction help with revision. These are additional features on paid tiers.

WellSaid Labsとは何ですか?

You paste a script and it returns a finished voiceover.
同社はワシントン州シアトルに本社を置いている。
Its models use deep learning and licensed voice data to generate speech.
Teams use it for e-learning, commercials, audiobooks, podcasts and product videos.
Fortune 500 customers pick it for polished digital experiences at scale.
The video below covers the studio workflow end to end.

WellSaid Labsの価格設定
Pricing is per seat, which matters for teams.

|---|---|---|
| トライアル | 無料 | Sampling four voice avatars before you sign up |
| クリエイティブ | 1ユーザーあたり月額50ドル | Solo creators with low-volume needs |
| 仕事 | 1ユーザーあたり月額160ドル | Teams needing around 144 audio hours per year |
| 企業 | 営業担当者へのお問い合わせ | プロジェクト数とセキュリティ管理は無制限です。 |
Pricing verified September 2026.
無料トライアル: Seven days, limited to four voice avatars. Sign-up asks for a work email rather than a personal address.
返金保証: No published refund window. Use the trial to test before you commit.
📌 注記： Commercial usage rights come with any paid subscription. Audio you make on the trial is not cleared for commercial purposes.
⚠️ 警告： Per-seat billing adds up fast. Four people on 仕事 costs $640 a month before any usage overage.
WellSaid Labsの主なメリット
Here is where the platform earns its price:
- Large voice library: Over 120 AI voices, each with its own personality. Accents and voice styles cover ads, training and entertainment.
- AI Director control: Adjust pitch, pacing and loudness at the word level. The newer HINTS system layers those notes across long scripts.
- Custom pronunciation: Save brand and product names in a shared repository. Everyone on the team gets the same pronunciation.
- Security compliance: SOC2 Type 2 and GDPR, plus HIPAA, ADA and WCAG standards. That opens healthcare and government work.
- Studio audio quality: Output reaches 96 kHz, which holds up in professional edits. No re-recording for background noise or room tone.
- API 建設業者: A RESTful API gives product developers low-latency access and helps content teams enhance productivity. Businesses report up to 80% savings against traditional voiceover costs.

機能比較
Both tools sit in the same category and solve opposite problems. These ten key features show where each one pulls ahead.
| 特徴 | スピーチファイ | ウェルサイドラボ |
|---|---|---|
| 開始価格 | 月額11.58ドル | 1ユーザーあたり月額50ドル |
| 無料プラン | ✅ | ❌（試用版のみ） |
| Reads Your Own PDF Files | ✅ | ❌ |
| 印刷されたテキストのOCR | ✅ | ❌ |

| 音声クローン | ✅ | ❌ |
| 複数の言語 | ✅ 60歳以上 | ❌ 英語のみ |
| Word-Level Voice Control | ❌ | ✅ |
| チームコラボレーション | ❌ | ✅ |
| 最適な用途 | Listening to digital content | Producing voiceovers for video |
1. AI音声と音声ライブラリ
スピーチファイ： The Speechify library offers more than 1,000 voice options built on neural TTS. Premium voices sound natural and clear. The free version drops you to non HD voices, which is the single biggest gap between tiers.
ウェルサイードラボ: The catalogue is smaller at 120+ AI voices, but each one is a fully directed アバター. Voices are trained on exclusive, licensed data. The company hit 99th-percentile quality scores back in 2020.
⚠️ 警告： Neither set of high quality voices carries the emotional range of a hired narrator. Reviewers flag this for both platforms.
2. Voice Control and Customization
スピーチファイ： Customizable options stop at speed, voice and pitch. That is enough for listening. It is not enough for a client-facing recording.
ウェルサイードラボ: The AI Director sets pitch, pacing and loudness word by word. HINTS goes further with layered, nested annotations across a long script. This is real direction, not a slider.
3. Reading Documents and OCR
スピーチファイ： This is the app’s ability that nothing else here matches. Optical character recognition lifts printed text off a photo, so physical books become audio. Speechify reads PDF documents, emails and articles the same way.
ウェルサイードラボ: There is no OCR reader and no document 受信トレイ. You paste a script into the editor. Converting text you own into a private listening queue is not what this tool does.
4. Apps, Platforms and Ease of Use
スピーチファイ： You get iOS, an Android app and a Chrome extension with synced progress. The user friendly interface takes about a minute to learn. Offline playback covers commutes with no signal.
ウェルサイードラボ: Everything happens in WellSaid Studio, a browser app with no mobile client. Text editing and audio production sit in the same window. There is no wait for rendering on short scripts.
5. 言語とアクセント
スピーチファイ： Over 60 different languages are supported. Language learners can replay a passage in a different language and follow the highlighting. AI dubbing moves a finished video into another track.
ウェルサイードラボ: Voice avatars are English only. Within English the range of accents and styles is wide. Rivals like Murf cover 20+ languages, which is the trade-off you accept here.
6. Voice Cloning and Dubbing
スピーチファイ： Cloning is available and Speechify lets you reuse the result across projects. Pair it with dubbing and one script becomes several audio files.
ウェルサイードラボ: Unauthorized cloning and deepfakes are banned outright. That is a deliberate ethics position, not a missing feature. Regulated buyers usually treat it as a plus.
7. チームコラボレーション
スピーチファイ： Accounts are personal. There are no shared projects or permission levels. Speechify users work alone.
ウェルサイードラボ: Projects are shared and collaboration levels are managed per person. The custom pronunciation repository keeps brand names consistent across creators. Real-time editing means two people are not exporting conflicting versions.
8. API and Product Developers
スピーチファイ： API access exists for teams embedding speech into their own app. It is aimed at reading experiences rather than broadcast audio.
ウェルサイードラボ: A RESTful API returns real-time speech with low latency. Product developers can spin up thousands of audio assets programmatically.
9. Security and Commercial Rights
スピーチファイ： Built for personal listening, so compliance paperwork is thin. Check the terms before you publish generated audio for commercial purposes.
ウェルサイードラボ: SOC2 Type 2 and GDPR are covered, along with HIPAA, ADA and WCAG. Any paid subscription includes commercial usage rights. Output runs up to 96 kHz, so it survives a real mix without background noise cleanup.
10. 価格設定とコスト
Here are both sets of plans side by side.
| ティア | スピーチファイ | ウェルサイドラボ |
|---|---|---|
| 無料 | 制限あり：月額0ドル | Trial: Free |
| 入場料支払い済み | 年間：月額11.58ドル | クリエイティブ：ユーザー1人あたり月額50ドル |
| 上位層 | 月額料金：29ドル/月 | ビジネスプラン：1ユーザーあたり月額160ドル |
| 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： The annual plan is the value pick at $11.58/month. A monthly subscription costs $29/month, which is more than double. Speechify premium is a personal purchase, so the free plan is a fair place to start.
ウェルサイードラボ: Creative at $50/user/month is a business line item. Business at $160/user/month buys roughly 144 audio hours a year. Against studio rates it still pencils out, with reported savings up to 80%.
💡 テスト結果： Speechify costs about $38 a month less than the cheapest WellSaid Labs seat. If your goal is listening rather than publishing, that gap decides it.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| 予算が限られている | スピーチファイ | Free plan plus $11.58/month annual |
| Reading PDF files aloud | スピーチファイ | OCR and document import |
| Voiceovers for video content | ウェルサイドラボ | Directed, broadcast-ready audio |
| Non-English narration | スピーチファイ | 60以上の言語に対応 |
| Shared team workflow | ウェルサイドラボ | Projects and pronunciation library |
| Regulated industries | ウェルサイドラボ | SOC2, HIPAA and WCAG coverage |
💰 あなたの予算
One is a personal subscription and one is a business cost. If a $50 seat needs sign-off, start with the cheaper option.
🔌 あなたの技術スタック
Speechify offers browser and mobile apps that sit next to whatever you already read in. WellSaid Labs offers an API and a studio that plug into a production pipeline.
🎧 How You Learn
Auditory learners get more from live text highlighting and adjustable reading speed. That combination only exists on one side of this comparison.
🎬 What You Publish
Narration for ユーチューブ videos, ads and training modules needs directed delivery. A reading app will sound flat next to it.
🆓 無料トライアルとデモ
Run a real document through the free plan before you pay. Do the same with the seven-day trial and a script you actually shipped.
🛟 サポートオプション
Consumer support means help centre articles and email. Enterprise plans add named contacts and security review.

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 content teams. We did not test enterprise SSO, bulk seat licensing, or long-run API load. Voice quality was judged by ear rather than by lab measurement. If you work in healthcare or government, run the compliance review yourself before committing.

🏆 受賞者：SPEEPHIFY
Speechify wins 4 of 7 categories.
最適な用途: students, readers with reading disabilities, commuters, language learners
Both products scored 4.2 in our ratings, so this came down to reach and cost. Speechify stands as the better default because it serves far more people at a fraction of the price.
Speechify text to speech is a reading tool. It turns your own digital content into audio you consume in day to day life, and it can save time on long documents.
WellSaid Labs is a production tool. It is a powerful tool for narration you publish, and the control it gives is worth the seat price to a team shipping video every week.
If you produce stories, ads or courses for an audience, WellSaid Labs is the better buy. For everyone else, the cheaper, more versatile app wins.
Even on the free plan it stays a valuable tool for anyone with a long reading list. That makes it the more versatile tool of the two for everyday use.
