Discontinued hosted model selector. Retained for migration and historical reference; no current inference route is implied.
Regions
Use the service-instance URL for the provisioned region. Product-edition and voice-specific availability apply; no universal residency guarantee inferred.
Endpoint pricing has not been collected. Check the provider for applicable rates.
Data & enterprise terms
Retention, training use, regional processing and enterprise terms have not been summarized for this endpoint.
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
IBM documents this proprietary Watson speech service model or managed voice family. The service exposes recognition/voice selectors, not downloadable trained checkpoints. Closed-weight classification is inferred for the product model; public Granite Speech research releases and referenced open research implementations are separate.
