Our verdict on Krisp Voice Isolation
Krisp Voice Isolation is a real-time SDK for Voice AI agents and speech-to-speech applications. It processes audio streams before speech-to-text, removing background voices and noise to support voice activity detection, turn-taking, and transcription accuracy. The product is aimed at developers building conversational agents, real-time communication systems, and other applications that need primary-speaker isolation. It supports server-side deployment, CPU-based processing, on-premises or customer-cloud deployment, and multiple audio streams with one loaded model.
Pricing is application-based and organized into Early stage and Enterprise plans. Early stage includes Voice Isolation, Voice Activity Detection, Turn Prediction, Interruption Prediction, Signal Detectors, and RTC noise and voice cancellation. Enterprise adds higher quality models, real-time server-side batch processing, model customization, dedicated engineering support, custom SLAs, and volume pricing. This structure gives developers access to core isolation and conversation signals earlier, while organizations with specific model, support, service-level, or volume requirements have a broader paid tier to consider.
Krisp’s strongest fit is its real-time feature depth and ecosystem coverage. Integrations include LiveKit, Pipecat, Daily, raw WebRTC, Vapi, and Ultravox, while bindings cover Python, Node.js, Go, Rust, C++, and C. Turn prediction, interruption prediction, and signal detection extend the SDK beyond basic noise removal. Developers choosing Krisp should need real-time stream processing and a supported integration path; teams looking for an uploaded-file workflow or export-oriented audio processing should choose a different type of tool.
