ElevenLabsとは何ですか？
ElevenLabs is an AI voice generator founded in 2022.
It converts text into spoken audio that sounds close to a natural human voice.
The platform reached a $3.3 billion valuation by 早い 2025.
Its suite covers text to speech, voice cloning, AI dubbing, AI music, and audio enhancement.
Speech synthesis runs in 29 languages, so a global audience can listen in its own language.
Many people call it the best AI voice generator, and the generative voice models are why.
Some people search for it as Eleven Labs AI, but it is the same product.
Here is a walkthrough of how the editor and the voice library work.
🏆 Winner: ElevenLabs
Clone your own voice in minutes. Generate AI voiceovers for ユーチューブ videos, podcasts, and training videos. The free plan gives you 10,000 credits per month.
ElevenLabsの価格設定
ElevenLabs mixes a monthly fee with character based usage. Here is what each plan costs.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | $0 | 10,000 credits monthly and up to 3 custom voices |
| スターター | 月額5ドル | 30,000 credits and hobby projects |
| クリエイター | 月額11ドル | YouTube creators and podcasters |
| プロ | 月額99ドル | Studios and high volume audio work |
Pricing verified September 2026.
無料トライアル: No card needed. The Free tier stays free and gives 10,000 credits per month.
返金保証: None advertised. You can cancel and drop back to the Free tier instead.
📌 注記： Larger organisations get custom pricing with dedicated infrastructure and stricter security standards. Contact sales for those details.
⚠️ 警告： Credits are consumed per character, not per minute. Long audiobook projects burn through a Creator plan faster than most users expect.
ElevenLabsの主なメリット
Here is what makes ElevenLabs worth a look:
- Realistic AI voices: The Eleven v3 model handles dialogue, accents, and emotional tags. That gives you advanced AI voices with real expression.
- AI音声クローン： Upload a sample and create a digital copy of your own voice. Voice cloning uses generative models and neural networks.
- AI dubbing: Translate and re-voice video into more than 30 languages. It keeps the original speaker’s voice tone, emotion, and timing.
- Conversational AI agents: Build real-time voice and chat agents for support, sales, and education. Latency is low and it links to Slack and Google Calendar.
- AI music and sound effects: Create studio-grade music and custom effects from a plain language prompt.
- ElevenReader app: Converts articles, PDFs, and e-books into spoken audio for listening on the move. Handy if you already read on Google Play Books.

ReadSpeakerとは何ですか？
ReadSpeaker is cloud based text to speech technology.
Its text to speech capabilities turn online, document, and app based text into a natural sounding voice.
The engine uses Deep Neural Networks to build human like voices.
Its neural TTS reads text aloud and highlights each word as it is spoken.
学校, businesses, and government agencies use these services for digital accessibility.
Students find a page more engaging when they can have the text read aloud, which supports both research work and academic integrity.
It supports over 50 languages and 200+ speech voices.
This video shows the reader in action on a live page.
リードスピーカー
Add a listen button to your websites in a few lines of code. Readers get highlighted text, adjustable reading speed, and MP3 downloads.
ReadSpeakerの料金プラン
There is no public price list. Here is what the vendor publishes.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| カスタム見積もり | ReadSpeakerは、お客様一人ひとりに合わせた料金プランをご用意しています。お見積もりをご希望の場合は、ReadSpeakerまでお問い合わせください。 | Schools, publishers, and public sector websites |
Pricing verified September 2026.
無料トライアル: Handled through sales. You request a demo rather than opening a self-serve account.
返金保証: Not published. Refund terms sit inside your contract.
📌 注記： Quotes usually scale with traffic, number of users, and which products you launch. TextAid and webReader are licensed separately.
⚠️ 警告： Custom pricing means no instant sign up. Budget for a sales call and a contract before you can test it on your own site.
ReadSpeakerの主な利点
Here is what makes ReadSpeaker worth a look:
- ダウンロードなし: ReadSpeaker webReader and docReader let people listen inside the browser. Nothing gets installed on the device.
- Legal compliance: It helps organisations comply with WCAG 2.2 and ADA accessibility requirements.
- Offline listening: Readers can download any page as an audio file in MP3 format.
- Personalized settings: Users adjust reading speed, pick from different voices, and change highlighting colors.
- Automated audio updates: When website or course content changes, the audio refreshes on its own.
- Support tools: Text highlighting, dictionary tools, and page masking help readers with visual impairments and cognitive barriers. Be aware that scanned notes and images need clean text first.

機能比較
These two AI tools overlap on one thing only: both are AI text to speech software. Everything after that splits apart. We compare ten areas below.
| 特徴 | イレブンラボ | リードスピーカー |
|---|---|---|
| 開始価格 | $0 free, then $5/month | カスタム見積もり |
| 無料プラン | ✅ | ❌ |
| AI音声クローン | ✅ | ❌ |
| Reads Live Web Pages | ❌ | ✅ |
| 言語 | 29 for speech synthesis | 50+ |
| 同期ハイライト | ❌ | ✅ |
| 対話型AIエージェント | ✅ | ❌ |
| AI音楽＆効果音 | ✅ | ❌ |
| WCAG 2.2 / ADA Support | ❌ | ✅ |
| 最適な用途 | Creators making AI voiceovers | Sites making content accessible |
1. リアルな音声生成
イレブンラボ: The Eleven v3 model produces some of the most advanced AI voices available today. It handles complex dialogue, accents, and emotional tags, so you can generate AI voices that carry real feeling. The result is natural sounding speech that many listeners cannot separate from a real human voice.
リードスピーカー: Its AI voice generator runs on Deep Neural Networks trained with deep learning techniques. The output is clean and steady rather than dramatic, closer to careful human speech than to performance. For long reading sessions, consistent quality matters more than performance.
⚠️ 警告： Does an AI generated voice sound perfect every time? No. Both tools stumble on unusual names, and you will still fine tune pronunciation by hand.
2. 音声の複製とカスタム音声
イレブンラボ: AI voice cloning is the headline draw. Upload a sample and the platform builds a digital copy of your own voice using generative models and neural networks. The Free tier already allows up to 3 custom voices.
リードスピーカー: It offers custom text to speech voices, but as a commissioned project rather than a self-serve upload. You work with the vendor to build a branded custom voice. That suits brands, not individuals.
3. Expressive Control and Speaking Styles
イレブンラボ: You get near complete control over delivery. Adjust ピッチ, pace, and emotional tone, then switch speaking styles for the same script. That flexibility is why it works for animated explainer videos, character work, and high quality voice overs.
リードスピーカー: Its Speech Engine SAPI focuses on clarity over drama. Readers control reading speed and voice choice rather than emotion. Deliberate, since a page read aloud should not sound theatrical.
4. Conversational AI and Virtual Assistants
イレブンラボ: Conversational AI agents interact in real time with low latency. Teams use them for customer support, sales, and education. They connect to Slack and Google Calendar, so virtual assistants can act on live data.
リードスピーカー: No agent ビルダー here. Its voice AI powers one-way narration and IVR systems instead. If you want a bot that answers back, this is not the tool.
5. Sound Effects, Music, and Dubbing
イレブンラボ: Generate studio-grade music and custom sound effects from a text prompt. AI dubbing re-voices a YouTube video into 30+ languages while keeping the speaker’s voice, emotion, and timing intact.
リードスピーカー: Nothing comparable. It reads what already exists and does not create music or effects. Media production sits outside its scope.
6. Accessibility and Reading Support
リードスピーカー: This is the strongest area. ReadSpeaker TextAid is a reading, writing, and studying tool for students with dyslexia and other learning difficulties. Highlighted text, page masking, dictionary tools, and word prediction all help, and the personal library stores uploaded files.
イレブンラボ: It helps with screen readers and alternative formats, and the ElevenReader app turns articles and e-books into spoken audio. Useful, but it will not make your site comply with anything.
7. Languages and Global Audience
イレブンラボ: Speech synthesis covers 29 languages, and AI dubbing stretches past 30. Fewer language options than the runner up, but each one supports emotion and cloning.
リードスピーカー: Over 50 languages and more than 200 voices. TextAid users pick from multiple languages and set their own reading speed. For a university serving international students, that breadth wins.
💡 プロのヒント: Count the languages you actually publish in. Most teams need six, not sixty.
8. Integrations and Developer Access
リードスピーカー: The Speech Cloud API feeds audio into apps, kiosks, and other websites. TextAid drops into an LMS as an LTI integration, and a browser extension reads online documents, Google Docs, Microsoft Word files, and personal documents on any device.
イレブンラボ: A developer API covers text to speech, cloning, and dubbing, and agents link to Slack and Google Calendar. The focus is on producing audio files, not on embedding a listen button in a page.
9. 使いやすさ
イレブンラボ: Create an account, paste a script, pick a voice, and generate speech. Voice generation time runs in seconds for short clips. Managing credits and versions gets fiddly once projects pile up, and you fill in pronunciation fixes yourself.
リードスピーカー: Readers get a user friendly interface: one button, then listen. Setup falls on your developer, who adds a script to the site. G2 reviews highlight how little training end users need.
10. 価格設定とコスト
プランを並べて比較してみましょう。
| プラン | イレブンラボ | リードスピーカー |
|---|---|---|
| 無料 | $0 | ❌ 無料プランはありません |
| 入場料支払い済み | Starter: $5/month | カスタム見積もり |
| 中級クラス | Creator: $11/month | カスタム見積もり |
| High tier | Pro: $99/month | カスタム見積もり |
イレブンラボ: You can test it today for nothing and upgrade for the price of a coffee. Credits are the real cost driver, so heavy users land on Pro sooner than the sticker price suggests.
リードスピーカー: ReadSpeaker has a custom pricing model for everyone. Contact them to get a custom quote. That fits procurement teams, but it blocks anyone who wants to try before talking to sales.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| To test with zero budget | イレブンラボ | Free tier, no sales call |
| 音声クローン | イレブンラボ | 自分の声をクローンする |
| A listen button on your site | リードスピーカー | Built for web pages |
| WCAG 2.2 or ADA compliance | リードスピーカー | Designed for accessibility law |
| Voiceovers for YouTube videos | イレブンラボ | Expressive, editable output |
| Support for students with dyslexia | リードスピーカー | TextAid studying tool |
💰 あなたの予算
ElevenLabs publishes every price, from $0 to $99/month. ReadSpeaker quotes per organisation, so a small blog rarely fits the model.
🔌 あなたの技術スタック
Running an LMS or a public sector site? The LTI integration and browser extension matter. Editing video instead? You want exported audio files.
📝 コンテンツの種類
Scripts you write for narration point to ElevenLabs. Pages, PDFs, and course material already published point to ReadSpeaker.
🎓 あなたの経験レベル
A beginner can generate professional voiceovers in ElevenLabs on day one. ReadSpeaker needs a developer for the initial launch.
🆓 無料トライアルとデモ
Sign up free at ElevenLabs and hear the voices in ten minutes. ReadSpeaker demos run through its team, so plan for a wait.
🛟 サポートとセキュリティ
ElevenLabs offers dedicated infrastructure and security standards on custom plans. ReadSpeaker writes contracts that protect institutional data from the start.

私たちのレビューで取り上げられなかったこと
We looked at individual creators and small teams. We did not 監査 ReadSpeaker contracts, test load at university scale, or measure how each engine handles rare dialects. Custom enterprise agreements on both sides sit outside this review. If you manage thousands of users, your priorities will differ from ours.

🏆 受賞者：ELEVENLABS
ElevenLabs wins 4 of 7 categories and holds the higher rating at 4.7.
最適な用途: AI voiceovers, voice cloning, dubbing, and ポッドキャスト 生産
ElevenLabs is the better artificial intelligence software for anyone producing audio. It is speech software that creates voices. ReadSpeaker is text to speech software that delivers voices into pages you already publish.
ReadSpeaker earns its 4.0 in a narrower lane. If your job is accessibility, e learning, or public sector compliance, it is the correct buy and ElevenLabs is not a substitute.
For everyone else, start with the free ElevenLabs plan. Ten minutes with it will tell you more than another hour of reading.
