1. AI Voices and Voice Library
已修改： Altered Studio offers a large voice library through its portfolio TTS voices. You can pick from many speech profiles and tones. Custom voice models are also supported for branded high quality voice content.
NaturalReader： NaturalReader provides over 1000 AI powered voices across more than 100 languages and dialects. Most of these voices are tuned for reading, study, and accessibility use cases. The newest and highest technology of AI voices is reserved for the Plus tier.
2. 语音克隆
已修改： Voice cloning is a core feature inside Altered. Rapid voice clone builds a vocal identity from a short recording. This advanced voice ai technology is built for media production and voice content creation platform work.
NaturalReader： NaturalReader does offer voice cloning, but the focus is reading aloud. The cloning option is positioned for personal narration projects, not full media production. Most users stay on the standard preset voices for reading.
3. Text to Speech and Speaking Styles
已修改： Premium text to speech includes 14 speaking styles like whispering and shouting. This emotive AI text to speech adds drama and flexibility to voice performances. It works well for dialogue, audio storytelling, and game scripts.
NaturalReader： NaturalReader’s text to speech technology focuses on clear, natural sounding audio. You can tweak speed and select different AI voices. There are no dramatic speaking styles, but the output is steady and easy to follow for long content.
4. Real Time Voice Changer
已修改： The voice changer in Altered offers real time voice morphing for live calls and games. It works on voice chats across messaging systems and other systems. Noise cancellation cleans up background noise during sessions.
NaturalReader： NaturalReader does not offer a real time voice changer. It is built for reading, not live voice alteration. If voice puppeteering or live morphing is your goal, this tool is not the right fit.
⚠️ 警告： Voice changers can be misused. Always disclose AI voice use where required and respect platform rules during voice chats.
5. Reading Files and Document Support
已修改： Altered is not built to read PDFs or physical text directly. Its focus is voice creation and audio production. You feed in scripts inside the editor rather than upload large files for reading.
NaturalReader： NaturalReader supports over 20 file types. You can convert any text, PDF, image, webpage, and physical book into audio. Documents like DOCX, EPUB, and TXT all play in the online reader.
6. Chrome Extension and Web Reading
已修改： Altered does not ship a public chrome extension for web reading. Workflows live inside Altered Studio’s online audio editor. This is fine for creators but limiting for casual browser use.
NaturalReader： NaturalReader has a chrome extension that reads any page in your browser. You can listen to news sites, YouTube videos descriptions, blog posts, and Google Docs. The extension also strips unwanted text such as URLs and footnotes.
7. Mobile App and Cross Platform Use
已修改： Altered is primarily a desktop and web app for the developer and creator workflow. It is not focused on a polished mobile reading experience. Most users build voice content on a computer with strong audio gear.
NaturalReader： NaturalReader has mobile apps for iOS and Android. You can continue listening across devices with a single account. This makes NaturalReader friendly for commuters, students, and busy professionals.
8. AI Voice Cleaning and Audio Editing
已修改： The AI voice cleaner is a standout tool inside the platform. It removes background noise and restores voice recordings to a clean state. The next generation audio editor also handles fine voice editing inside the same app.
NaturalReader： NaturalReader does not include a noise cleaning tool or full audio editor. It is meant to generate audio files from text rather than fix existing recordings. For voice editing, creators look elsewhere.
9. Use Cases and Target Users
已修改： Altered serves podcasters, video game publishers, and film production teams. It is built for human talent who want speed without losing creative control. The platform also supports voice editing, audio storytelling, and online audio editor work.
NaturalReader： NaturalReader serves students, professionals, and people with learning disabilities. NaturalReader EDU licenses extend the same tool to schools and universities. The personal version is strictly for individual listening, while NaturalReader Commercial covers content creators who need a commercial license.

我们的评测没有涵盖的内容
This comparison focused on individual creators, students, and small teams. We did not test large enterprise rollouts, deep API workflows, or full 安全 audits for either product. Voice cloning ethics and legal use vary by region, so we did not give specific legal guidance. If you are using either tool for high stakes commercial work, review the official terms and licensing pages first.

Altered 在 7 个类别中赢得了 4 个。
最适合： Voice creators, podcasters, game studios, and media production teams
NaturalReader and Altered are two very different products that share the word “voice.” NaturalReader is the better choice for reading, study, and accessibility. Altered is the better choice for creators who build voice content for a living.
NaturalReader shines when you want clean, natural sounding audio from documents, web pages, and physical text. If you are a 学生, a busy professional, or someone with reading-related learning disabilities, the chrome extension and mobile app are hard to beat.
Altered is the broader voice content creation platform. With voice cloning, voice morphing, multiple voice AI technologies, and a next generation audio editor under one roof, it is the better pick for media production. The $30/month entry price also gives more for less.
If you only need a clean reading voice for personal use, start with NaturalReader’s free version. If you create audio for an audience or work with voice performances, Altered is the better long-term home.
