Bảng giá Speechify
Speechify costs nothing to start. Here are the current plans.
| Kế hoạch | Giá | Tốt nhất cho |
|---|---|---|
| Giới hạn | 0 đô la/tháng | Testing the basic version |
| Hàng năm | 11,58 đô la/tháng | Daily readers who commit for a year |
| Hàng tháng | 29 đô la/tháng | Short projects with no lock-in |
Pricing verified September 2026.
Dùng thử miễn phí: Yes. New accounts get a 3-day premium trial with card details on file.
Đảm bảo hoàn tiền: Refunds are handled case by case through support, not by a published window.
📌 Ghi chú: The Speechify Limited plan gives you non HD voices and a daily cap. HD voices, faster reading speed, and a 150,000-word monthly allowance sit behind Speechify Premium. Additional features such as AI summarization sit on the paid tier too.
⚠️ Dữ liệu conflict: Our CSV lists a $29 monthly subscription and $11.58/month annual billing. Public research summaries claim $139 per year with no monthly option. The annual figure matches ($11.58 × 12 = $138.96), but we could not reconcile the monthly plan. Speechify pricing also varies from country to country. Check the checkout page for your region.
Những lợi ích chính của Speechify
Here is what makes the app worth a look.
- Reads almost any source: You simply upload a file, paste a link, or scan a page. It handles pdf files, emails, and study material.
- OCR reader for paper: Point your camera at physical books and it converts printed pages into an audio file.
- Adjustable reading speed: Playback stretches to 900 words per minute. The average reading speed sits near 250.
- Text highlighting in sync: Words light up as they play. Academic research links dual input to better retention.
- Runs everywhere: An iOS app, an Android app, and a Chrome extension keep your Speechify library in sync.
- Built for accessibility: Listening reduces mental fatigue for auditory learners and anyone who struggles with dense digital content.
Những điều nhóm chúng tôi nhận thấy
Của chúng tôi nhà văn used the app for a week of reports and research papers. Here is what stood out during that time.

- Playback reaches 900 words per minute for fast listeners
- Text highlighting keeps your eyes on the line being read
- Over 60 languages and more than 1,000 voice options
- Free plan and 3-day trial let you test before paying
❌ Nhược điểm

Cái gì đã bị thay đổi?
Altered là một nền tảng tạo nội dung giọng nói dành cho sản xuất truyền thông.
The desktop and web app is called Altered Studio.
It packs multiple voice AI technologies into one interface.
You get a Voice Changer, premium text to speech, voice cloning, and an AI Voice Cleaner.
The company pitches it as a next generation audio editor.
Podcasters, game publishers, and film studios are the target buyers.
The walkthrough below shows the editor handling a full session.
Runner Up: Altered
Clone a voice, morph a take, and clean the audio in one editor. A free trial of the Creator plan is open on the website.
Giá cả đã thay đổi
Three tiers cover hobby work through studio work.
| Kế hoạch | Giá | Tốt nhất cho |
|---|---|---|
| Miễn phí | 0 đô la/tháng | Trying the voice changer |
| Người sáng tạo | 30 đô la/tháng | Solo podcasters and voice creators |
| Chuyên nghiệp | 90 đô la/tháng | Studios and game development teams |
Pricing verified September 2026.
Dùng thử miễn phí: Yes. You can sign up for a Creator plan trial on the Altered website.
Đảm bảo hoàn tiền: None published. Professional and Enterprise terms are quoted on the pricing page.
📌 Ghi chú: The paid tiers unlock custom voice models, transcription, and translation. Enterprise buyers are asked to request a quote rather than pay a list price.
⚠️ Cảnh báo: The entry paid tier costs more than double Speechify’s annual rate. Budget for render minutes too, since cloning and morphing burn through them faster than plain narration.
Những lợi ích chính của việc thay đổi
These are the reasons studios pick it up.
- One editor, many engines: Voice morphing, cloning, and cleanup share a single timeline. That cuts app switching during media production.
- Sao chép giọng nói nhanh chóng: A short sample builds a usable model. The voice cloning technology copies a vocal identity without booking human talent again.
- 14 Phong cách Nói: Emotive text to speech covers whispering through shouting. Dialogue stops sounding flat.
- Công cụ thay đổi giọng nói thời gian thực: Live morphing works in voice chats with noise cancellation running underneath.
- Công cụ làm sạch giọng nói bằng AI: Background noise gets stripped from raw voice recordings before you export audio files.
- Chỉnh sửa lịch sử: Track versions of a project and roll back to an earlier take.
Những điều nhóm chúng tôi nhận thấy
Our writer cloned a voice and re-cut a short narration script. Here is what came out of that session.
The clip below covers the same session from the editor’s side.
Ưu điểm và nhược điểm đã thay đổi
✅ Ưu điểm
- Cloning, morphing, and cleanup live in one online audio editor
- Ultra-low latency morphing works during live calls and gaming
- Custom voice models plus transcription and translation
- Game developers and podcast producers rate it well in reviews
❌ Nhược điểm
- No document reader, no OCR, and no mobile listening app
- Entry paid plan starts at $30/month
- Cloning someone else’s voice raises consent and copyright questions
So sánh tính năng
These two products overlap on one thing only: they both speak. Everything after that splits apart. Here are the ten key features that decide the pick.
| Tính năng | Phát biểu | Đã thay đổi |
|---|---|---|
| Starting paid price | 11,58 đô la/tháng | 30 đô la/tháng |
| Gói miễn phí | ✅ | ✅ |
| Document reading (PDF, email, web) | ✅ | ❌ |
| OCR for printed text | ✅ | ❌ |
| Nhân bản giọng nói AI | ✅ | ✅ |
| Bộ đổi giọng nói thời gian thực | ❌ | ✅ |
| Audio editing and cleanup | ❌ | ✅ |
| Mobile app and Chrome extension | ✅ | ❌ |
| Tốt nhất cho | Reading and listening | Voice production |
1. Voice Library and Voice Options
Speechify: The catalogue runs past 1,000 voice options, and you can adjust speed and pitch on each one. Converting text into audio takes one tap, and the paid tiers serve high quality voices. Premium voices sound close to human like voices. The free tier serves non HD voices, which are flatter but perfectly usable for skimming.
Đã sửa đổi: The extensive voice library is smaller in raw count but tuned for performance work. Portfolio TTS voices cover narration and character reads, and 14 speaking styles change delivery from a whisper to a shout.
2. Nhân bản giọng nói bằng AI
Speechify: Cloning exists, but it is a side feature. You record a sample and the app reads your documents back in that voice. It is a novelty for readers rather than a production tool.
Đã sửa đổi: AI voice cloning is the core product. Rapid Voice Clone turns a short sample into a reusable model, and the result carries the source vocal identity across a whole script. Studios use it to cut re-record sessions.
⚠️ Cảnh báo: Clone your own voice or one you have written permission to use. AI-generated audio raises live legal questions about authorship and copyright.
3. Voice Morphing and Live Changing
Speechify: There is no voice changer here. The app plays a chosen voice and stops there. Nothing morphs your own microphone input.
Đã sửa đổi: Voice morphing swaps character, accent, and style on a finished take. The real time voice changer runs with low enough latency for live voice chats and gaming, with noise cancellation applied on the way through.
4. Document Import and OCR
Speechify: This is where Speechify stands alone. You can import text by copy-paste, file upload, or a web link. The app’s ability to scan a page with your camera turns physical books into playable audio.
Đã sửa đổi: There is no ocr reader and no document library. You paste a script or upload an audio file. Reading a PDF aloud is simply not what the tool is for.
Loading...
Speechify: More than 60 languages are supported, so language learners can hear a passage in a different language while reading the original. AI dubbing pushes the same idea into video.
Đã sửa đổi: The platform transcribes audio and translates content into multiple languages inside the same project. That suits dubbing a game build across different languages more than casual study.
6. Audio Editing and Cleanup
Speechify: Text editing is available before playback, so you can fix a typo the narrator would trip on. Post-production audio editing is absent.
Đã sửa đổi: Voice editing sits at the centre. The AI Voice Cleaner pulls background noise out of raw takes, and the Voice Editor reshapes delivery line by line for audio storytelling.
7. Custom Voice Models
Speechify: You pick from the shipped catalogue. There is no training pipeline for building a house voice from scratch.
Đã sửa đổi: Voice Training builds custom models you own and reuse. Voice puppeteering lets you act a line out and map that performance onto a different voice, which keeps voice performances consistent across episodes.
8. Reading Speed and Listening Experience
Speechify: Speed runs to 900 words per minute, and text highlighting tracks the audio in real time. Offline playback covers commutes, allowing users to keep going without a signal. The listening experience is the whole product.
Đã sửa đổi: Output is a finished file you play elsewhere. There is no reading queue, no highlighting, and no speed slider for consumption.
9. Platforms and Developer Access
Speechify: iOS, an Android app, a Chrome extension, and API access cover most workflows. The user friendly interface is the same across all of them.
Đã sửa đổi: Work happens in Altered Studio on desktop and web. There is no phone app for casual use, which is fair for a studio tool.
10. Định giá & Chi phí
Here are both ladders side by side.
| Cấp độ | Phát biểu | Đã thay đổi |
|---|---|---|
| Miễn phí | Limited — $0/month | Free — $0/month |
| Vé vào cửa đã trả phí | Annual — $11.58/month | Creator — $30/month |
| Hạng cao nhất | Monthly — $29/month | Professional — $90/month |
Speechify: The annual route is the cheapest way in at $11.58/month. Paying month to month costs $29 instead, so the yearly commitment saves real money if you read daily.
Đã sửa đổi: Creator at $30/month is professional software priced for professional output. Nobody buys this to listen to email. It earns its keep when a clone replaces a booked session.
Các kịch bản khác nhau

Những điều mà bài đánh giá của chúng tôi chưa đề cập
We looked at individual and small-team use on the September 2026 versions. We did not test Enterprise contracts, bulk seat licensing, or API load at scale. Accessibility certification and screen-reader compatibility were outside our scope, and regional pricing differences mean your checkout total may not match ours.

🏆 NGƯỜI CHIẾN THẮNG: SPEECHIFY
Speechify wins 4 of 6 categories.
Phù hợp nhất cho: students, commuters, and anyone with a document backlog
Speechify wins because it fits more people, not because it does more. It is a popular app with a narrow job: convert text you already have into audio and get out of the way. Speechify users mostly want to save time, and it does that at $11.58/month. It enhances productivity in a boring, repeatable way.
Altered is the better product for a smaller room. If you sell voice work, the cloning, morphing, and cleanup stack is a powerful tool. For a studio it is also a valuable tool in plain money terms, since one avoided recording day covers months of subscription. Teams that want to enhance productivity across a slate of projects will feel that first.
Pick by output. Listening means Speechify. Publishing means Altered. Our full Speechify review covers the reading side in more depth.
