ai-coustics

ai-coustics is a Berlin-based audio-intelligence company providing a real-time speech-enhancement SDK for Voice AI systems. Its Quail, Rook, Quail VAD, Quail Voice Focus, and Tyto models remove background noise, isolate the primary speaker, detect voice activity, and score audio risk to make automatic speech recognition (ASR) more accurate and voice-activity detection steadier in the real world. The SDK runs on the proprietary AirTen CPU-first inference runtime (no GPU, no ONNX dependency) with sub-30ms latency, and ships official bindings for Python, Rust, Node.js, C, C++, and WebAssembly, plus LiveKit and Pipecat integrations. Authentication uses self-service license keys or short-lived JWTs; a legacy REST API was sunset in favor of the SDK. Backed by Partech.

ai-coustics publishes 1 API on the APIs.io network. Tagged areas include Company, Ai/Ml, Audio, Speech Enhancement, and Voice AI.

ai-coustics’ developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, changelog, and 15 more developer resources.
