1. Chuyển văn bản thành giọng nói
Speechify: Speechify text to speech is built around consumption. The speechify app converts written text into spoken words using premium voices, hd voices, and non hd voices on the free plan. It reads pdf documents, articles, and emails out of the box.
Trí tuệ nhân tạo bị biến đổi: Altered’s premium text to speech is built around creation, not reading. The voice library includes portfolio tts voices and supports 14 Speaking Styles for dialogue, whispering, and shouting. Combined with text editing tools and the voice editor, it outputs polished voice content for media projects rather than casual listening.
⚠️ Cảnh báo: If you want a tool that simply reads articles to you on a commute, the speechify text to speech model fits better than Altered’s creator focused approach.
2. Voice Options and Voice Library
Speechify: Speechify offers over 1,000 ai voices across 60+ different languages. Voices include human like voices designed for long listening sessions. The speechify library covers narration styles, accents, and reading-friendly tones.
Trí tuệ nhân tạo bị biến đổi: Altered’s extensive voice library focuses on character and performance work. Voice creators can use multiple voice ai technologies, ai voice cloning for vocal identity, and voice puppeteering tools. It’s built for high quality voice content rather than reading volume.
3. Nhân bản giọng nói bằng AI
Speechify: Speechify includes ai voice cloning on higher premium subscription plans. You can clone your own voice or a celebrity-style voice and use it in the app. The cloning is solid but secondary to the core reading experience.
Trí tuệ nhân tạo bị biến đổi: Voice cloning technology is at the heart of Altered Studio. Rapid voice clone produces a usable model from a short voice sample. It’s built for repeatable voice content creation across episodes, characters, and projects.
4. Voice Morphing and Real Time Voice Changer
Speechify: Speechify does not offer voice morphing or a real time voice changer. It’s focused on converting text into speech, not transforming a live voice into another character.
Trí tuệ nhân tạo bị biến đổi: Altered’s voice morphing and real time voice changer are core features. The advanced voice ai technology lets you alter your voice for voice chats, gaming, or live streams. Background noise cancellation runs while you talk.
5. PDF and Document Reading
Speechify: Speechify reads pdf files, pdf documents, and almost any digital content directly. You can simply upload, paste a link, or import text. The app’s ability to handle long documents is one of its biggest strengths.
Trí tuệ nhân tạo bị biến đổi: Altered is not built to read pdf files for you. It’s an audio editor for voice content, so document reading isn’t part of the workflow. If listening to documents is your goal, this is the wrong tool.
6. OCR and Printed Text Reading
Speechify: Speechify uses optical character recognition to read printed text from photos. The ocr reader can scan physical books, handwritten notes, and even some signs. This makes it a versatile app for offline materials.
Trí tuệ nhân tạo bị biến đổi: Altered does not advertise optical character recognition. It expects you to bring your own text or audio for voice processing. OCR is outside the scope of what this online audio editor does.
7. Reading Speed and Text Highlighting
Speechify: The speechify app lets you adjust reading speed up to 900 words per minute, far above the average reading speed. Real-time text highlighting follows along while audio plays. This boosts comprehension and helps auditory learners stay focused.
Trí tuệ nhân tạo bị biến đổi: Altered does not include a speed reader or synced text highlighting. Its focus is on producing finished voice files, not optimizing your listening experience. Speed and pitch adjustments exist but apply to voice editing, not reading flow.
8. Voice Cleaning and Voice Editing
Speechify: Speechify is not a voice editing tool. It generates audio output from text but doesn’t offer multi-track voice editing or noise removal for your own voice recordings.
Trí tuệ nhân tạo bị biến đổi: Altered includes an ai voice cleaner that removes background noise from existing recordings. The voice editor adds history editing, so creators can roll back changes. These tools simplify audio production for voice creators.
9. Platforms and Apps
Speechify: Speechify is available on iOS, the android app, and as a chrome extension. You can install speechify today on most devices and listen across them. The app also offers offline content listening for when you’re away from Wi-Fi.
Trí tuệ nhân tạo bị biến đổi: Altered Studio runs as a web-based online audio editor. There is no chrome extension and the platform is built for desktop voice work, not mobile listening. Integrations focus on media production workflows.
10. API and Developer Access
Speechify: Speechify provides API access on higher tiers, so developers can plug speechify text into their own products. This is useful for apps that want to add reading support quickly.
Trí tuệ nhân tạo bị biến đổi: Altered offers developer access on Professional and Enterprise plans for voice content creation pipelines. This suits studios automating voice generation across many projects.

| Cấp bậc cao hơn | 29 đô la/tháng (thanh toán hàng tháng) | 90 đô la/tháng (Gói chuyên nghiệp) |
Speechify: Speechify pricing is much cheaper on the entry paid plan when billed annually. The premium subscription unlocks premium voices, hd voices, and the 150,000 word per month allowance. There is no monthly subscription that matches annual pricing, but the value at $11.58/month is hard to match for a reading-focused app.
Trí tuệ nhân tạo bị biến đổi: Altered AI’s Creator plan starts at $30/month. That’s higher than Speechify, but you get a full set of voice cloning, voice morphing, and audio storytelling tools. For a professional voice creator producing voice content for clients, that price often pays for itself quickly.

What Our Review Didn’t Cover
This comparison focused on individual users and small creator teams. We didn’t deeply test enterprise voice cloning rights, custom Altered Professional features, or Speechify’s trường học and team plans.

🏆 WINNER: SPEECHIFY
Speechify thắng 5 trên 7 hạng mục.
Phù hợp nhất cho: Listening to articles and pdf documents, accessibility for reading disabilities, students and professionals who want to enhance productivity
Speechify and Altered AI are two very different products that share the term ai voices. Speechify is a popular app for converting text into spoken words you can listen to. Altered Studio is a voice content creation platform for professional voice creators.
