Pricing and plan details come straight from each vendor’s current page.
Speechifyとは何ですか?
Speechify is a text to speech app that reads your written text out loud.
It started as a personal fix for the founder’s dyslexia.
The Speechify app now helps people with ADHD, low vision, and other reading disabilities.
Optical character recognition lets it convert text from a photo of printed text.
You can also simply upload PDF documents or paste a web link.
It runs on neural AI technology, and the whole reading experience is built around one idea.
Speechify stands on the belief that listening beats decoding when you are tired.
Here is a walkthrough of the interface before we get into cost.
🏆 受賞者：Speechify
Reads books, emails, and PDF files aloud on any device. The free plan costs nothing to try.
Speechifyの価格
Speechify cost depends on how you pay. The premium subscription plans break down like this.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 限定 | 月額0ドル | Testing the basic version |
| 年間 | 月額11.58ドル | Daily readers who commit for a year |
| 毎月 | 月額29ドル | Short projects and one-off study sprints |
Pricing verified September 2026.
無料トライアル: Yes. New Speechify users get a 3-day trial of premium voices.
返金保証: Refunds are handled case by case through support, not a fixed window.
📌 注記： The Speechify premium plan covers roughly 150,000 words per month with premium voices. The Speechify Limited tier keeps you on non HD voices and caps how much you can play each day.
⚠️ Data conflict flagged: Our research notes say Speechify sells only a $139 yearly plan and no monthly subscription. Our CSV pricing sheet lists a $29/month option alongside the $11.58/month annual rate. We publish the CSV figures above and note the gap here. Prices also shift by country.
Speechifyの主なメリット
Here is what makes this a valuable tool for heavy readers:
- OCR reader for physical books: Point your camera at a page and the app converts text to audio. Printed pages and handwriting both work.
- Reading speed up to 900 wpm: Average reading speed sits near 250 wpm. Speechify lets you push far past that, which enhances productivity on a long backlog.
- Text highlighting in real time: Each word lights up as it is read. Academic research links pairing audio with sight to better recall.
- Works everywhere you read: There is an iOS app, an Android app, and a Chrome extension. Offline mode keeps playback going without signal, allowing users to listen on a plane.
- Over 60 different languages: A versatile tool for language learners who want the same passage in a different language.
- Study tools built in: On-repeat playback, note extraction, and AI summaries sit inside the Speechify library. Customizable options cover speed, voice, and highlight colour.
私たちのチームが気づいたこと
私たちの 作家 ran Speechify through a week of research papers and newsletters. Here is what stood out from that hands-on time:
Speechifyの長所と短所
✅ メリット
- Free version lets you test the app before paying
- OCR reads printed text, PDF files, and images
- Reading speed adjusts up to 900 words per minute
- Text highlighting keeps your eyes on the right line
- Runs on iOS, Android, and Chrome with offline playback
❌ デメリット
- Reviewers call it expensive next to cheaper rivals
- Voices sound clear but thin on emotional nuance
- The free plan has limited features and non HD voices
- No commercial voiceover export for client work
Reviocer とは何ですか?
Revoicer is an AI voice generator that produces human sounding voiceovers from text.
Some directories list it under its longer name, Revoicer Voice Synthesizer AI.
This is AI text to speech built for publishing, and it runs in a browser with nothing to install.
You paste your script, pick a voice, and download the audio file in just a few clicks.
Revoicer brings emotion controls to that process, which most rivals skip.
This is not a new service. It has been sold to video creators for years.
The video below shows the editor and the preview tool in action.
🥈準優勝：Revoicer
Records emotional AI voice overs for video in just a few minutes. Backed by a 60-day refund.
Revoicerの価格
Revoicer pricing splits into three tiers. There is no free plan here.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| リボイス標準 | 月額37ドル | ソロクリエイターが制作するショートビデオ |
| リボイスプロ | 月額47ドル | Voice cloning and background music |
| リボイスエージェンシー | 月額127ドル | Teams selling voiceover work to clients |
Pricing verified September 2026.
無料トライアル: No. You cannot test the tool before you buy.
返金保証: 60 days, no questions asked.
📌 注記： The higher tiers unlock voice cloning, background music, and SRT subtitle export. The refund window is your real trial, so test hard in the first week.
⚠️ Data conflict flagged: Our CSV feature sheet lists 80+ voices and 40+ languages. Vendor marketing material claims 250+ AI voices across 50+ languages. We use the CSV numbers in our tables and flag the gap rather than pick a side. Ask support before you buy on voice count alone.
Revoicerの主な利点
Here is why creators pay for it instead of hiring human voiceover artists:
- Voice emotions: Switch a line from a serious tone to a more joyful tone without re-recording. That extra layer is the main draw.
- Speech speed and pauses: Slow a line down or add pauses to build tension in adventure videos.
- Male female and kid voices: The library covers all three, so one account handles a full cast.
- Multiple accents: Revoicer features multiple English accents, including a UK accent, an Australian accent, and an Ireland accent.
- 迅速な対応: A finished voiceover takes roughly a minute, which is where the tool saves real money.
- API アクセス: A text-to-voice API lets you wire speech voices online into your own product.
- Support use cases: Teams create pre recorded voiceovers for common questions, which lifts the customer support experience.

- Quality drops on less common languages
機能比較
Ten key features decide this one. The summary table gives you the shape of it, and the sections below explain why each row landed where it did.
| 特徴 | スピーチファイ | リボイス |
|---|---|---|
| 開始価格 | 月額0ドル | 月額37ドル |
| 無料プラン | ✅ | ❌ |
| 光学文字認識 | ✅ | ❌ |
| 声の感情 | ❌ | ✅ |

| 音声クローン | ✅ | ✅ |
| Chrome拡張機能 | ✅ | ❌ |
| Commercial Audio Export | ❌ | ✅ |
| テキストのハイライト表示 | ✅ | ❌ |
| 最適な用途 | Reading and studying | ボイスオーバー制作 |
1. Voice Library and Voice Options
スピーチファイ： The catalogue runs past 1,000 voice options, with celebrity-style reads on the premium plan. You get high quality voices on the paid tiers, built for long listening rather than performance. The free version drops you to non HD voices, which sound flatter and pick up a faint digital hiss some people mistake for background noise.
リボイスャー: The library is smaller but tuned for delivery. Every voice in the set is a paid HD voice, since there is no free tier to downgrade you. Marketing pitches it as the most natural sounding text to speech engine you can buy, and calls it the most amazing collection of text to speech voices; and the natural sounding voices in the set do carry emotion well. A few still read stiff.
2. Voice Emotions and Tone
スピーチファイ： There is no emotion dial. The app aims for a steady, neutral read that holds up across a 40-page report. That is the right call for studying and the wrong call for marketing video.
リボイスャー: Voice emotions are the headline feature. One script can carry a serious tone that helps convey sophistication, or a joyful tone for a product launch. Picking the right tone takes two or three previews, not a re-record.
3. Reading Speed and Speech Speed
スピーチファイ： Playback stretches to 900 words per minute. Most people settle near 350 after a week. Since average reading speed is closer to 250, that alone can save time on a long reading list.
リボイスャー: Speech speed here is about pacing an edit, not consuming faster. You slow a line to match a slow pan, or trim it to fit a cut. Speech pauses emphasize specific words and let you stress even whole phrases.
4. OCR, PDF Files and Physical Books
スピーチファイ： This is the widest gap in the comparison. The OCR reader turns printed text, screenshots, and even handwriting into spoken words. You can photograph physical books page by page and get an audiobook out of it.
リボイスャー: No optical character recognition at all. You import text by pasting it or typing it. That is fine for a script and useless for a textbook.
⚠️ 警告： OCR accuracy drops on glossy pages and tight book gutters. Flatten the page and kill the glare before you scan.
5. Multiple Languages and Language Support
スピーチファイ： Support covers 60-plus different languages, プラスAI dubbing that moves a finished recording into a different language. Language learners get real mileage from hearing a passage in two tongues back to back.
リボイスャー: Revoicer supports 40-plus languages per the feature sheet. Language support is solid on the majors and patchy further out, and voice quality tracks the language you pick.
6. 音声クローン
スピーチファイ： Cloning is available and aimed at hearing your own voice read your notes back. It is a listening feature dressed as a production one.
リボイスャー: Cloning sits on the higher tiers and targets brand consistency. One cloned model reads every video you publish, so your digital content keeps the same perfect voice month after month.
7. Accents and Voice Types
スピーチファイ： Accents exist but are not sorted for casting. You scroll a long list of human like voices and audition them one at a time.
リボイスャー: Accents are a filter, which matters when you are casting. Kid voices are the standout, since almost no rival offers them. Create voiceovers for a character-led ad in only a few clicks.
8. Apps, Platforms and Ease of Use
スピーチファイ： There is an iOS app, an Android app, a Chrome extension, and offline playback. The user friendly interface is the reason it works as a popular app for non-technical readers.
リボイスャー: Browser only. There is no dedicated Revoicer app for phones, which rules out editing on a commute. Inside the browser the layout is clean and beginners get to a first export fast.
9. Text Editing, API and Other Features
スピーチファイ： Text editing is light. You fix a mispronounced name and move on. API access, AI summaries, and note extraction round out the additional features, and the roadmap points at a Voice AIアシスタント.
リボイスャー: Editing is where the advanced features live and where high quality voiceovers get finished. Background music, a preview tool, and SRT subtitle export are the other features worth paying for. Its text-to-voice API can also handle audio content of varying lengths inside your own app.
10. 価格設定とコスト
Both charge monthly. Only one lets you look first.
| ティア | スピーチファイ | リボイス |
|---|---|---|
| 無料 | 制限あり：月額0ドル | ❌ なし |
| 入場料支払い済み | 年間：月額11.58ドル | Revoicer Standard: $37/month |
| 中級クラス | 月額料金：29ドル/月 | Revoicer pro: $47/month |
| 最高級 | ❌ なし | Revoicer Agency: $127/month |
スピーチファイ： The annual rate of $11.58/month is the cheapest paid entry point in this matchup. The monthly subscription at $29 is steep by comparison, so the yearly commitment carries the value.
リボイスャー: Entry costs three times as much, and the money is gone before you hear a single output. The 60-day refund softens that, but this is not a one time payment product despite how some resellers pitch it.
💡 プロのヒント: One paid month of Revoicer costs more than three months of Speechify’s annual plan. Script your videos first, then buy for the month you actually record.

私たちのレビューで取り上げられなかったこと
Our full Speechify review and Revoicer review go deeper on setup than this page does. Here, we looked at individual and small-team use. We did not test either API under load, and we did not run bulk licensing or team billing. Voice quality was judged in English, so a different language may behave differently. Prices shift by country and by promo, so check the checkout page for your own region before you commit.

🏆 受賞者：SPEEPHIFY
Speechify wins 6 of 9 categories.
最適な用途: Students, auditory learners, professionals with long reading lists, and anyone with reading disabilities
Speechify text to speech wins because it costs less and asks nothing up front. It is a versatile app for day to day life, and the listening experience holds up over hours of use. Speechify reads to you; that is the whole point.
Revoicer is the stronger tool the moment your audio has an audience. Emotion control, kid voices, and commercial licensing make it a powerful tool for voiceover creation. It is also the only one of the two you can sell work with.
Pick the one that matches the job you need to enhance productivity on. If you are converting text for your own ears, take Speechify. If you are producing sales videos or explainers for clients, the extra spend on Revoicer pays for itself.
