description: 'Krisp is a Voice AI platform whose real-time speech-enhancement models run on over 200 million devices, licensed
  by Discord, Twilio, and VMware among others. Beyond its consumer AI Note Taker, Krisp ships a developer surface: the AI
  Voice SDK family (VIVA for voice AI agents — voice isolation, turn prediction, interruption prediction, VAD; and RTC for
  human-to-human calls — accent conversion, bidirectional noise cancellation, background voice cancellation) across Windows,
  macOS, Linux, Web (JS/WASM), iOS, and Android with C++, Python, Node.js, Go, Rust, and JavaScript bindings, plus framework
  integrations for LiveKit, WebRTC, and Pipecat. Krisp also runs a self-serve Voice Translation API — a streaming WebSocket
  speech-to-speech translation service covering 61 languages behind a REST session-token mint — and a programmatic SDK and
  model download REST API for CI/CD pipelines.'

  name: Krisp Voice Translation API
  description: Real-time speech-to-speech voice translation delivered over a persistent WebSocket session. A REST call mints
    a short-lived session key, the client opens a WSS session with a JSON config message (source/target BCP-47 language, voice,
    custom vocabulary, translation dictionary), then streams 16 kHz mono PCM or Opus frames; the server streams synthesized
    translated speech back on the same socket alongside JSON transcript, translation, and error events. Krisp advertises 61
    languages and a 99.9% uptime SLA.

  description: A REST API that returns short-lived download URLs for a licensed Krisp AI Voice SDK version package and its
    associated model files, intended for CI/CD pipelines, automated testing, and custom deployment scripts. Authenticated
    with an api-key Authorization header; the returned S3 links expire within seconds (expires_in, e.g. 300).
