What is Altered AI?

Altered AI is a specialized AI voice content creation platform. It helps you create, edit, and transform voice recordings using artificial intelligence.

Think of it like a photo editor — but for your voice.

Here’s the simple version:

You record your voice. Altered Studio changes it to sound like someone else. You can also type text and turn it into speech. The advanced voice AI technology handles everything behind the scenes.

The tool focuses on voice morphing. That’s what makes it different.

Unlike basic text to speech tools, Altered lets you drive a voice with your own performance. You keep the emotion. You keep the timing. But the voice changes completely.

The platform supports the creation of custom voice models. You can also transcribe audio and translate content into 75+ languages. This makes Altered Studio a true next generation audio editor for anyone in media production.

Who Created Altered AI?

Ioannis Agiomyrgiannakis (known as “Yannis”) started Altered in 2018.

The story: He spent nearly 8 years as a research scientist at Google. He worked on Tacotron 2 — one of the biggest breakthroughs in synthetic speech. He saw that voice was blocking people from making great video content. So he built Altered AI to fix that.

Today, Altered has raised $3.39 million in seed funding. The team has about 14 employees.

The company is based in London, United Kingdom. It’s backed by investors like Big Pi Ventures and Innovate UK.

Professionals in game development and podcast production praise Altered Studio for its impact. Altered is helping push forward the democratisation of game development.

• Clone Any Voice Fast: The rapid voice clone feature creates a realistic copy of any voice from just a few minutes of audio. This voice cloning technology provides game-changing benefits for voice creators.
• Sound Like a Pro Without a Studio: The AI voice cleaner removes background noise, filler words, and mouth sounds. Your voice recordings come out clean and professional.
• Reach Global Audiences: Transcribe and translate your audio content into 75+ languages. Dub your podcasts or videos without hiring translators. This supports your voice content creation across borders.
• Keep Creative Control: Voice puppeteering lets you guide AI voices with your own performance. You control the emotion and delivery. The tool enhances audio storytelling while keeping the human element alive.
• All-in-One Platform: Altered Studio integrates multiple voice AI technologies into a single user friendly application. No need for 5 different tools. Voice editing, cloning, cleaning, and TTS all live in one place.

Best Altered AI Features

Here are the standout features that make Altered Studio worth your attention.

1. AI Voice Cloning

This is the heart of Altered AI. You upload a few minutes of voice recordings. The tool builds a custom voice model that sounds like the real person.

I tested the ai voice cloning with my own voice. The result was scary good. It captured my tone and vocal identity perfectly.

The best part? You can create unlimited Hollywood-quality voice clones. The fine-tuning process runs locally on your computer for privacy.

2. Voice Training

Voice training takes cloning to the next level. You feed the system more data. It learns your speaking patterns better.

With longer training samples, the output gets more natural. The system picks up subtle things like how you pause or stress words.

This is perfect for voice creators who want a custom AI voice that truly matches their vocal identity. Human talent can use this to scale their work across multiple projects.

3. Voice Morphing

Voice morphing is what makes Altered different from every other tool. You speak into the mic. The AI changes your voice to sound like someone else in real time.

This is speech-to-speech technology. You keep your emotion and timing. But the voice changes completely. It’s like voice puppeteering — you drive the performance.

Altered Studio allows users to modify voices for different characters, accents, and styles. This is great for both media production and real-time interactions. Multiple voice options let one person play many roles.

4. Text-to-Speech

Type your text. Pick a voice. Hit generate. That’s it.

Altered’s text to speech isn’t just basic robot talk. It offers “Speaking Style” or emotive TTS. You get 14 speaking styles including whispering and shouting.

The extensive voice library gives you access to portfolio TTS voices and professional voice options. You can create audio content that sounds natural and full of feeling. This is where Altered’s advanced voice capabilities really shine.

5. Voice Editor

The online audio editor is where you fine-tune everything. Cut, trim, and adjust your audio right inside Altered Studio.

The History Editing feature lets you track and revert to previous versions of your audio project. This saves you from losing work.

You don’t need a separate audio editing app. This voice editing tool handles it all. It’s a true next generation audio editor built for voice content creation.

6. Speaking Styles

This feature gives you 14 ways to deliver a line. Whisper. Shout. Sound sad. Sound happy. Sound angry.

The speaking styles make your voice performances feel real. A character in a video game can sound excited or scared. Not flat and boring.

This is where Altered enhances audio storytelling and professional audio projects. You get fine control over how each line sounds. No other tool gives you this many options for voice performances.

7. AI Voice Cleaning

Recorded audio with background noise? The AI voice cleaner fixes it.

It removes static, dog barks, and other unwanted sounds. It also fixes mouth clicks and filler words. Your voice recordings sound like they were made in a pro studio.

I tested it on a noisy coffee shop recording. The result was impressive. The background noise disappeared, but my voice stayed clear and natural.

8. Transcription and Translation

Altered can turn spoken words into written text fast. It supports 75+ languages.

You can also translate your transcriptions into other languages. Then dub your content using AI voices.

This makes it easy to reach global audiences. Record once, publish everywhere. The platform supports the creation of custom voice models that work across languages.

9. Real-Time Voice Changer

This is the real time voice changer feature. It changes your voice during live calls or gaming sessions.

Altered Studio’s real time voice changer is useful for voice chats on diverse communication platforms. It provides realistic voice alterations with effective noise cancellation.

Real-Time Performance of Altered AI provides ultra-low latency morphing. That means no delay. Your voice changes happen instantly during live calls or gaming. It uses only 1-4 CPU cores, so it won’t slow down your computer.

Altered AI Pricing

Altered AI keeps pricing simple with three plans.

Free trial: Yes — the free plan lets you explore Altered Studio’s basic features. Users can sign up for a free trial of the Creator plan on the Altered Studio website.

Money-back guarantee: For Professional or Enterprise subscriptions, users need to visit the pricing page on the website for details.

📌 Note: All plans are billed annually. The prices shown are monthly costs when paying yearly.

Is Altered AI Worth the Price?

At $30/month, the Creator plan is a good deal. You get voice cloning, voice morphing, text to speech, and the voice editor. Most competitors charge more for less.

The $90/month Professional plan makes sense for studios. You unlock everything including priority support and advanced features.

You’ll save money if: You currently hire voice actors for multiple projects. Altered cuts those costs fast.

You might overpay if: You only need basic text to speech once a month. The free plan or a cheaper tool would work fine.

My Experience with Altered AI

Here’s what actually happened when I used Altered AI:
