Which one is for you
Pick Altered if
- Fits if you want a different voice on Discord or in games

Look elsewhere if
- 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
Pick Respeecher if
- Fits if you're a studio that needs a particular voice recreated, with consent
- Works for sound engineers who act a line in Pro Tools and want it in another voice
Look elsewhere if
- Skip it if you want to clone a voice yourself, as custom voices are Enterprise-only and need a signed agreement
- Tight if you make lots of short clips, as Creator allows 100 requests a day and TTS only 350
- Not for you if you want hundreds of voices, as subscriptions get 25+ and Power 40+
- Watch out: pay-as-you-go packs carry no API access, and the real-time API is billed apart at $2 per 60,000 characters
- Watch out: the free trial's limits aren't stated, and there's no free plan, phone app or desktop app

Worth knowing
Altered

- 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.
Respeecher

- Pay-as-you-go packs, from $5 for 20,000 characters or 5 minutes of speech-to-speech to $250 for 500 credits, include commercial usage rights but no API access.
- The real-time TTS API is billed separately at $2 per 60,000 characters, about an hour of speech.
- Subscriptions cap daily text-to-speech requests: 350 on TTS only, 100 on Creator and 500 on Power.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
