What our research says

Altered

Altered is one of the few voice tools built around editing a performance you already recorded rather than generating one from scratch, and the licence attached to each tier is spelled out plainly. The catch is the two-axis meter: you can run out of morphing minutes or tokens independently, and the commercial licence only starts at the EUR 87 tier.

Pros

Speech-to-speech morphing keeps the original delivery instead of re-reading a script
Free tier plus a card-free week-long Creator trial
Desktop apps for Windows and Mac in addition to the browser studio
Token consumption rates per provider are published on the pricing page

Cons

API access, multi-seat and custom voice models are Enterprise-only
Two separate meters (minutes and tokens) make cost harder to forecast
Commercial licensing requires the Professional tier; lower tiers carry attribution or creator terms

Resemble AI

If you came here for voice cloning, the product you remember has been withdrawn: Resemble now sells the opposite service, catching cloned voices and faces, and the pricing and API reflect that. As a detection vendor it is a credible shortlist entry next to Pindrop and Reality Defender, with per-second metering that is easy to trial and an on-prem option for regulated buyers.

Pros

One REST API covers audio, video and image detection, watermarking and speaker identity
Pay-per-use Flex tier lets you measure accuracy on your own data before committing to seats
Containerised on-premises install for buyers who cannot send media to a cloud
Published per-unit rates and a public benchmarks page, which most detection vendors keep behind sales

Cons

Voice generation has been discontinued as a commercial product; existing TTS integrations need a new vendor
Per-second detection pricing adds up quickly on long recordings or video
Seat plans jump straight from $0 to $350 a month with nothing in between
No headquarters address on the terms page, only Delaware as governing law
