Base model
Timbre model familySource for Base model (opens in a new tab)

Provider explicitly names the family; immutable base weights/version unknown.

Model terms
Altered licenses its application and voices without providing source-access rights; reverse engineering and unauthorized model redistribution are restricted. Free outputs require attribution and noncommercial use. Creator permits eligible individuals/companies of up to five employees with relevant trailing-year revenue/funding below USD 100,000. Professional uses the stated commercial license. Custom voice creation requires source rights and speaker consent; continued use requires a valid subscription. No public model weights verified.Source for Model terms (opens in a new tab)
Creation privacy
Generic terms permit content/output collection for diagnostics and service improvement and reserve a private record of source-voice files. Privacy-policy retention is purpose/necessity-based, not a fixed inference TTL. Local-cloning and Standard Real-Time Pro pages make narrower local-processing promises; discounted realtime plans explicitly permit anonymized voice data for improvement. Exact precedence, contractual exceptions and cloud handling remain unresolved.Source for Creation privacy (opens in a new tab)
Reference audio
Current comparison:5s minimum,20s suggested,40s maximum for best results. Historical announcement says5–15s but its training step says4–8s. These are inconsistent guidance/version scopes, not one silently combined limit.Source for Reference audio (opens in a new tab)
Language coverage
Cross-lingual operation using Timbre; mainly English training means results are strongest for acoustically similar languages. No exhaustive tested language list.Source for Language coverage (opens in a new tab)
Published price
Rapid cloning is marked included in all Studio plans. Using a resulting voice consumes the applicable morph quota; separate per-voice enrollment tariff not established.Source for Published price (opens in a new tab)

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

API model ID
Not collected

No callable public model ID or immutable checkpoint selector verified; UI names and voice-profile IDs are not API contracts.

Access
Access through https://altered.studio/ and the licensed Studio desktop app where supported. Models and voice profiles depend on plan and installed voice library. Enterprise API/on-premise arrangements exist, but per-model public routes, authentication and deployment contracts were not verified.
Regions
Processing residency depends on deployment; no universal model-specific region guarantee verified.
Endpoint availability
Studio API access is marked Enterprise-only. Commercial desktop distribution is license-bound, not open-weight distribution.Source for Endpoint availability (opens in a new tab)

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Voice enrollment creates a customer adaptation/profile using Altered technology. This workflow is explicitly managed; each customer voice is not a newly enumerated native base checkpoint.
