Gradium Voice Cloning and Voice Design 30

No x402, MPP or L402 (0). Plan prices and credits are public, 1 credit a character for speech, with no dollar price per unit, as cartesia-voice-cloning is read. Creating a clone uses no credits in the docs (10). The free plan has 45,000 credits a month, 5 custom voices and Voice Design, and the site says no credit card is required. Commercial use starts on the $12 plan (20). Signup is a browser flow in Gradium Studio (0). 0+10+20+0 = 30.

Resemble AI Voice Cloning API 0

No x402, MPP or L402 (0). The per-second speech and per-slot prices were read on 30 September from app.resemble.ai/billing/api/v1/plans, a billing data endpoint this run doesn't read, so that reading is struck, and the pricing pages can't be re-read under the terms, so no per-unit price for the API stands today (0). The changelog's $2 for later clones is the Flex web app's, not the API's. No API cloning below Business per the 2 October check, and the free first clone in the Flex web app captures a card for later clones (0). Signup is a human browser flow (0).

The changelog's 29 June 2026 entry says Resemble 'began deprecating all older voice models', with no notice period. The model versions page now lists seven end-of-life TTS models, Chatterbox and Chatterbox-Turbo among them, and says voices still on them can no longer generate audio until upgraded to Resemble Ultra, but gives no dates or notice policy (10 of 20).

Gradium Voice Cloning and Voice Design 48

Graded for voice cloning as the other listings in this category, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line. API keys per organisation in a header, revocable and able to expire, with no scopes found (20 of 30). No consent or verification field and no watermark. The Terms make the client obtain the consent of anyone whose voice is a sample and bar impersonation without explicit authorisation, and the API FAQ says explicit consent is required (6 of 20). The Terms grant Gradium a licence to use Client Data to improve its services and train its models, with no opt-out found, and zero data retention (paid plans) excludes voice samples, so samples are kept and may be used for training (2 of 15). Organisation roles and a member list, with no per-call audit log found (5 of 15). SOC 2 Type II and ISO 27001:2022 audited by A-LIGN, a trust centre and security@gradium.ai.

Resemble AI Voice Cloning API 54

Graded for voice cloning, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line, since the API returns audio and IDs rather than third-party text. Plain Bearer API keys, no scopes found (20 of 30). The terms say Resemble may require verbal consent from the person cloned. The API reference has no consent field, though the Node SDK still sends an optional consent value added in 2023. Watermarking and deepfake detection sit in the same account (4 of 20). The privacy policy of 14 August 2026 says customer voice data isn't used to train general-purpose models or for research, recordings and voice models are kept while the account is active plus a 30-day grace period, and synthesis text and audio aren't kept after delivery (12 of 15). Clone slots and usage readable through the Billing API, no per-call log found (8 of 15). The Secureframe trust centre lists ISO 27001:2022 as certified, an annual third-party penetration test, and SOC 2 Type 2 still in its observation period on 2 October, two days after the date it gave for the report. No security.txt, disclosure policy or bug bounty found (10 of 20). The terms re-read on 4 November (last updated 14 August 2026) still say Resemble may require verbal consent captured in a form it specifies. OSV lists no records for @resemble/node or resemble. The rest per the 2 October check, not re-read on 4 November (Resemble's terms bar automated means).
