Age-progressing synthetic voices for AAC, preserving a vocal identity through five stages. Initial English release is documented; underlying checkpoint identities are not.
Rosie/Josh samples establish these English varieties. The separate 16-language child-voice portfolio is not Growing Voices coverage.
Voice controls
Five age stages spanning childhood to young adulthood. Public Rosie/Josh audio samples illustrate selected stages, not API voice IDs or separate base models.Source for Voice controls (opens in a new tab)

No current per-voice licence or API rate established for Growing Voices.
Access & pricing
Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.
No public checkpoint or voice-stage API identifier collected.
Access
Initial English voices announced available through the provider offering; confirm application, voice-stage and licence delivery. No public inference endpoint established.
Regions
Deployment and processing location unverified.
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Product-specific consent, child-voice usage and deployment terms require confirmation; general provider privacy statements are not a complete service contract.
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
Provider-developed proprietary evolving voice technology offered for AAC. Named as a managed voice component because the announcement does not identify a standalone private neural checkpoint for each stage or speaker.
