Architecture
Custom deep neural network synthesizing speech waveforms; exact architecture, parameter count and checkpoint revisions are not specified.Source for Architecture (opens in a new tab)
Deployment options
Licensed SDK for Windows, macOS, Linux, Android and iOS; cServer for Windows/Linux; CerePlay mobile/offline deployment. SDK development and commercial redistribution require different licensing arrangements.Source for Deployment options (opens in a new tab)

CerePlay and cServer are separately documented products, not additional base models.

Audio sample rates
cServer CereWave: 16,000 Hz, cServer CereWave: 24,000 HzSource for Audio sample rates (opens in a new tab)

The same page assigns 8/48 kHz to Unit Selection voices. Do not copy those rates into the neural engine or treat resampled cloud output as a native model rate.

Voice controls
Provider describes adaptive voice construction, changing voice characteristics and expressive synthesis. This does not establish a public fine-tuning endpoint or universal per-voice controls.Source for Voice controls (opens in a new tab)
Stock voice catalog
Not collected

No authoritative complete CereWave model/voice/version mapping collected. The voice shop now publishes a desktop deprecation notice rather than a full inventory.

Published price
Not collected

Commercial SDK/server rates are arranged through sales; cloud character-pack pricing does not establish a CereWave-specific deployment tariff.

Documentation discrepancy
The shop says Windows SAPI5 and macOS voices are being deprecated while voice development continues through Capacity AI. This is not evidence that all CereWave models, cServer or Cloud are retired. Product availability and historical checkpoint revisions require separate confirmation.Source for Documentation discrepancy (opens in a new tab)
Model terms
Desktop voices have personal single-device licence terms. SDK developer licences allow integration/testing; commercial release requires an agreement through sales. Do not apply desktop terms as the complete commercial or cloud contract.Source for Model terms (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 public cloud model selector; access is through the licensed product and voice build.

Access
Licensed SDK; annual developer access and separate commercial distribution terms. Documentation lists Windows, macOS, Linux, Android and iOS; exact runtime/model-build compatibility needs confirmation.
Regions
Local or customer-managed deployment; no provider-hosted region implied.

Endpoint pricing has not been collected. Check the provider for applicable rates.

Data & enterprise terms

Commercial deployment and redistribution require product-specific licensing. No current customer deployment data policy established by the reviewed marketing pages.

API model ID
Not collected

No public cloud model selector; access is through the licensed product and voice build.

Access
Licensed Windows/Linux synthesis server, cSpeech C/C++ and Python clients and SAPI 5 client. Neural voices use documented 16/24 kHz output; simultaneous streams do not establish a public streaming HTTP model endpoint.
Regions
Local or customer-managed deployment; no provider-hosted region implied.

Endpoint pricing has not been collected. Check the provider for applicable rates.

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

CereProc retains proprietary software rights and licenses use rather than redistributing source or weights. Its voice and FAQ pages identify CereWave as the custom DNN waveform model. This family record does not classify the separate Unit Selection engine as a neural model.
