Architecture
Speech recognition → text translation → speech synthesisSource for Architecture (opens in a new tab)
Languages
60+ languages; query the authenticated language endpoint for current BCP-47 localesSource for Languages (opens in a new tab)

The product page says 61; another company article says 63. Do not turn examples or marketing totals into a verified exhaustive language list.

Context caching
Not collected
Audio sample rates
16 kHz mono input and outputSource for Audio sample rates (opens in a new tab)
Provider-reported latency
Typically 800–900 ms in steady state after initial speech contextSource for Provider-reported latency (opens in a new tab)

Provider estimate, not an end-to-end latency guarantee for every language pair.

Generation controls
One source and one target per session; two sessions for bidirectional calls. Optional domain vocabulary, translation dictionary, transcripts and background voice cancellation.Source for Generation controls (opens in a new tab)
Partner model providers
ElevenLabs, Soniox, Google Cloud PlatformSource for Partner model providers (opens in a new tab)

Listed for translation backend support; exact model IDs and per-request routing are not disclosed here. AWS provides infrastructure and Daily.co audio streaming.

Usage metering
Subscription with included translation minutes and per-minute overage; exact numeric tariff not collectedSource for Usage metering (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 exact public checkpoint selector confirmed for this access route.

Access
Create a developer account and API key, issue a temporary session token on your backend, then stream real-time audio over WebSocket.
Regions
Krisp Cloud; exact processing region is not established by these public sources
API endpoint URL
wss://streaming.krisp.ai/vt; token endpoint: GET /v2/sdk/voice-translation/session/tokenSource for API endpoint URL (opens in a new tab)
Authentication
API key on the backend; session-token TTL 5–1,440 minutesSource for Authentication (opens in a new tab)

Token TTL is not a model context window or a verified maximum audio-session length.

Request quotas
700 REST requests/minute; concurrent session cap depends on the account. Enterprise IP whitelisting can bypass the global REST limit.Source for Request quotas (opens in a new tab)
Streaming audio chunks
Pace audio in real time; default Python example uses 20 ms frames, 640 PCM bytes at 16 kHz monoSource for Streaming audio chunks (opens in a new tab)
Included free allowance
60 minutes free to startSource for Included free allowance (opens in a new tab)

Trial allowance, not a zero-dollar ongoing inference tariff.

Partner model providers
ElevenLabs, Soniox, Google Cloud PlatformSource for Partner model providers (opens in a new tab)

Listed for translation backend support; exact model IDs and per-request routing are not disclosed here. AWS provides infrastructure and Daily.co audio streaming.

Billing basis
Subscription with included translation minutes and per-minute overage; exact numeric tariff not collectedSource for Billing basis (opens in a new tab)
Model routing
Managed pipeline; users choose languages/voice, not a pinned backend STT, translation or TTS modelSource for Model routing (opens in a new tab)

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

Data & enterprise terms

Voice Translation uses Krisp and licensed third-party models. API terms state that content is processed transiently, without content retention or training; limited billing/security/operational metadata remains. This is a cloud service, not the on-device SDK privacy contract.

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

The API terms identify proprietary Krisp models combined with licensed third-party models and reserve model weights/parameters. This record is a managed closed service pipeline, not a claim that Krisp created every component or has one end-to-end checkpoint.
