| 特征 | Speechify | 改造后的人工智能 |
|---|---|---|
| 起价 | 每月 11.58 美元（年付） | 每月 30 美元（创作者） |
| 免费计划 | ✅ | ✅ |

1. 文本转语音
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.
改造后的AI： 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.
⚠️ 警告： 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.
改造后的AI： 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. AI语音克隆
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.
改造后的AI： 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.
改造后的AI： 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.
改造后的AI： 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.
改造后的AI： 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.
改造后的AI： 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.
改造后的AI： 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.
改造后的AI： 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.
改造后的AI： Altered offers developer access on Professional and Enterprise plans for voice content creation pipelines. This suits studios automating voice generation across many projects.
定价与成本
让我们来并排比较一下这些定价方案。
| 计划 | Speechify | 改造后的人工智能 |
|---|---|---|
| 免费计划 | 每月 0 美元（限时优惠） | 每月 0 美元（免费） |
| 入场费 | 每月 11.58 美元（年付） | 每月 30 美元（创作者） |
| 更高层级 | 每月 29 美元 | 每月90美元（专业版） |
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.
改造后的AI： 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.

最适合： 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.
Altered is excellent for podcasters, video game publishers, and film teams who need voice cloning, voice morphing, and a real time voice changer. The platform supports the creation of custom voice models and lets you transcribe audio and translate content into multiple languages. It is a powerful tool when audio is the product.
However, if you simply want a versatile tool that reads written text aloud, Speechify is the better choice. It’s cheaper, easier to use, and built specifically for the reading experience. For most readers, students, and accessibility users, Speechify stands as the more practical pick.
