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)
Default per-user fast endpoints: 500 requests per 300 seconds; slow endpoints: 100 per 300 seconds. HTTP 429 includes Retry-After. Published slow-endpoint list uses older paths, so exact v2 route classification needs confirmation. Plan daily TTS quotas are separate.Source for Request quotas (opens in a new tab)
Response format
Create a project and folder, then an original recording and conversion order. Poll recording/conversion state until done with an output URL; inspect errors. Completed recordings download from /storage and projects can export ZIP. Multiple conversions in one order do not establish a discounted batch API.Source for Response format (opens in a new tab)
Model selection
Not collected
Voice, accent, narration-style and response model UUIDs are not a verified map to private base checkpoints. Marketplace API v2 and OpenAPI 0.6.0 are interface revisions.
Model terms
Marketplace July 2024 terms reserve provider technology rights and permit recording review for abuse prevention. Customer data includes generated voiceovers, subject to use restrictions. Trial plans exclude commercial work; organizations above USD 1 million annual revenue need a custom plan for commercial use. Credits expire after one year unless separately agreed. Marketplace conditions are not automatically Space terms.Source for Model terms (opens in a new tab)
Subscription plans
Pay-as-you-go packs offer TTS characters OR STS minutes. Pricing matrix marks API access unavailable on these standalone packs; subscription API entitlement must not be inferred from buying credits., TTS-only subscriptions include API access; regular monthly tiers are USD 4 / 30,000 characters, 18 / 100,000, 89 / 500,000, 149 / 2 million and 499 / 10 million. First-month offers apply to the first two tiers., Creator: 400,000 TTS characters plus 90 STS minutes; Power: 3 million characters plus 900 STS minutes. These are shared subscription bundles, not additive TTS and STS subscriptions., Pricing matrix daily TTS quotas: pay-as-you-go 200; TTS-only 350; Creator 100; Power 500. These are plan limits, not model input lengths. Subscriptions do not roll over; purchased credits last one year., Enterprise: custom pricing, API/plugin/on-premise arrangements, custom voices and real-time conversion subject to a separate agreement. Unlimited concurrency is an enterprise plan claim, not the Space default.Source for Subscription plans (opens in a new tab)
Monthly rollover/credit lifetime also described in FAQ and Marketplace terms. Annual prices are monthly equivalents under yearly billing.
Documentation discrepancy
Endpoint prose requires narration_style_id for TTS and lists optional text_language, but public OpenAPI 0.6.0 omits both and instead exposes tts_voice_id. The public schema limits text to 1–1,000 characters. Resolve deployed-version differences before integration. Marketing FAQ says API is included while the plan matrix excludes standalone pay-as-you-go.Source for Documentation discrepancy (opens in a new tab)
Contradictory prose and pricing matrix are linked separately; no authenticated request made to resolve runtime behavior.
Original recording is multipart data with parent_folder_id and microphone. Optional calibration estimates source pitch; automatic calibration is available. Calibration does not create a new base model.Source for Reference audio (opens in a new tab)
Voice controls
voice_id selects a target; accent_id and semitones_correction adjust STS conversion. Resulting pitch combines source pitch, default target shift and correction. Calibration can use a specified or current account profile.Source for Voice controls (opens in a new tab)
Language coverage
FAQ says speech-to-speech can accept any language, but training is mainly English and a slight English accent can appear. This is a provider claim, not verified uniform accuracy across languages.Source for Language coverage (opens in a new tab)
Published price
Marketplace credit packs or Creator/Power subscriptions. Minutes are speech-to-speech allowances; the same bundle also offers TTS under its stated alternative or combined allowances.Source for Published price (opens in a new tab)

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
Managed catalogue voice-conversion workflow using Respeecher technology. Individual speaker profiles and calibration IDs are not identified private base checkpoints.
