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)
Authentication
Marketplace gateway.respeecher.com uses api-key, or session_id cookie plus X-Csrf-Token. Space keys cannot be reused.Source for Authentication (opens in a new tab)
Request quotas
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.

Maximum prompt characters
1,000Source for Maximum prompt characters (opens in a new tab)

Published API schema maximum, not a web-editor limit or Space TTS constraint. Minimum one character.

Voice controls
Narration styles are required in the prose conversion guide; FAQ limits them to a subset of voices and English, French and German. Exact catalogue language coverage and style-to-model mapping are unverified.Source for Voice controls (opens in a new tab)
Published price
Marketplace subscriptions and credit bundles use characters, audio minutes and plan periods. Rates below preserve bundle conditions; they are not token prices.Source for Published price (opens in a new tab)

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

Proprietary hosted speech workflow. Its voice catalogue and historical backend revisions are not publicly mapped to individual private checkpoints; represented as a managed component rather than a newly invented base model.
