Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 39 of the 43 other AI voice generators we grade
Altered makes a desktop real-time voice changer, Real-Time Pro, that works as a virtual microphone with voice skins, accent translation, speaker isolation and a voice-restoration model. It also runs Altered Studio, a separate voice production tool with speech-to-speech morphing, voice cloning and text to speech.
To get you started, here are 9 things to know about Altered, taken from its own pages and our grades.
It needs audio routing into your call app, and a powerful enough computer.
- 1
Best for changing your voice live on calls
Altered changes your voice in real time and can translate accents, running on your own computer.
- 2
Paid plans start at $2.50 a month
As its pricing page puts it: $2.50 per month, billed yearly ($5 billed monthly).
- 3
There is a free plan
20 minutes of processing a day, Isolate speech enhancement and 4 voice skins each day, on AI Improvement Program terms.
- 4
It runs on 3 platforms
Windows, macOS and Web.
- 5
Real-time voice skins
Changes both the timbre and the accent of your voice live through a virtual microphone any Windows or Mac app can select. The FAQ lists 20 voice skins.
- 6
Accent translation
Converts an accent to American or British English during calls while keeping the speaker's own voice; aimed at call centers.
- 7
Speaker isolation
Isolate suppresses background noise and competing speakers by locking on to the user's voiceprint.
- 8
A 2.6 GPA, above 39 of 43
That is against the other AI voice generators we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Altered you would be making a voice model trained on your recordings. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for changing your voice live on calls
Altered changes your voice in real time and can translate accents, running on your own computer. The cheaper and free tiers need you to let it train on your anonymized voice data, and the real-time part needs a machine with 8 or more cores.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | Voice Skins is $2.50 a month billed yearly ($5 monthly), under 60% of the category's cheapest quarter of $5. The $10 plans for accent translation or voice restoration are $6 yearly if you accept the data terms. |
| Free plan and trial | C | Free is 20 minutes of processing a day with Isolate and 4 voice skins daily, but it requires consent to anonymized voice data training. |
| Features | C | Voice skins, accent translation, speaker isolation, voice restoration and a studio. Altered Studio is a separate product with pricing we couldn't read. |
| Ease of use | C | No store rating on record. It needs audio routing into your call app, and a powerful enough computer. |
| Platforms and integrations | B | Windows, Mac and web, with Discord, Zoom, Teams, Meet, Skype, WhatsApp and Minecraft. No phone apps are listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Altered is for
- Fits if you want a different voice on Discord or in games
- Works for a call center that wants accent translation on live calls
Who it is not for
- Not for you if you won't let it train on your voice, since the cheapest and free tiers require it
- Tight if you stay free: 20 minutes of processing a day
- Watch out: real-time use suits a machine with 8 or more cores, as it runs on your CPU
- Watch out: Altered Studio is a separate product, and the site footer still shows 2022-2023
- Skip it if you want a phone app, as none is listed
Good to know
Good for
- Gamers who want voice and accent skins on a low-cost plan
- Call-center teams standardizing accents on live calls
- People who need real-time voice restoration in calls
Worth knowing
- The cheapest and free tiers require consenting to anonymized voice data being used to improve Altered's models.
- Altered Studio is a separate product; its pricing was not readable on the pages we checked.
- Processing runs on your CPU; Altered says real-time use suits a machine with 8 or more cores.
- The site footer still shows a 2022-2023 copyright date, so some marketing text may lag the product.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Altered you would be making a voice model trained on your recordings. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 2.6 is higher than 39 of the 43 other AI voice generators we grade. It costs $30 a year.
What you could not
- A voice model trained on your recordings.
- A voice model, which you can rent by the minute but not make.
- Audio cleaned up live as you speak.
- Speech turned into text you can trust.
- A real app for macOS and Windows. Something home-made would be a web page.
- It plugs into other products, Discord, Zoom and Microsoft Teams among them.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Altered’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
