What ai-coustics is
ai-coustics provides an audio intelligence layer that prepares unpredictable audio as machine-ready input for Voice AI systems. Its Quail speech enhancement models target speech-to-text accuracy and can reduce word error rate by as much as 30%. Quail Voice Focus suppresses competing voices to isolate a foreground speaker, while Tyto scores incoming audio for potential downstream failures and gives a cause. Its voice activity detection model is designed for complex real-world environments without separate denoising tools. The SDK runs speech enhancement, voice activity detection, and audio analysis on CPU inside a customer's application. The company says on-device processing has sub-40 ms latency and that processed audio stays on the customer's infrastructure. Documentation lists Python, Node.js, C, C++, Rust, and WebAssembly, with integration guidance for LiveKit and Pipecat. The Developer Platform offers a free SDK trial. The service is offered to commercial or independent professionals and legal persons under public law.
