Creation privacy
Website policy retains personal data as necessary, with legal exceptions and international transfers. Its separate AI Voice Assistant appendix promises no model training or voice cloning for assistant conversations and specifies 12-month transcript/technical-data retention. Those assistant-only terms are not a Space TTS or Marketplace inference-retention guarantee.Source for Creation privacy (opens in a new tab)
FAQ describes a closed beta used by corporate clients, arranged per project and unavailable through standard Marketplace access. Enterprise pricing mentions custom realtime options.Source for Endpoint availability (opens in a new tab)
Published price
Not collected
Project-specific quote; no numeric real-time STS tariff verified. Do not apply Space TTS character rates.
Access & pricing
Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.
No immutable checkpoint selector verified; voice IDs identify catalogue profiles.
Access
Project-based beta via provider contact. No public streaming STS endpoint or self-service Marketplace route verified.
Regions
Inference residency not verified; company location is not processing-region evidence.
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Service-specific terms and exact inference retention require confirmation. Website policy retains personal data as necessary, with legal exceptions and international transfers. Its separate AI Voice Assistant appendix promises no model training or voice cloning for assistant conversations and specifies 12-month transcript/technical-data retention. Those assistant-only terms are not a Space TTS or Marketplace inference-retention guarantee.
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
A proprietary project-based realtime voice service is documented, but its distinct checkpoint identity and relation to offline models are unpublished.
