ai-coustics vs ElevenLabs

ai-coustics provides audio-processing tools for Voice AI systems, preparing incoming sound for speech recognition and other downstream tasks. Its Quail models enhance speech and can reduce word error rate by as much as 30%; Quail Voice Focus suppresses competing voices to isolate the foreground speaker. Tyto predicts whether audio may cause downstream failures and returns a score with the cause. A voice activity detection model is designed for complex real-world environments without a separate denoising tool. The SDK runs enhancement, voice activity detection, and audio analysis on CPU within the customer’s application. The company says on-device processing has sub-40 ms latency, and audio processed by the SDK remains on the customer’s infrastructure. Integration options include Python, Node.js, C, C++, Rust, and WebAssembly, with guidance for LiveKit and Pipecat. A free SDK trial is offered through the Developer Platform, and paid plans start at $135 a month billed annually. Startup includes 100,000 minutes per month; Pro is $360 a month billed annually, Business is $540 a month billed annually, and Enterprise starts at $2,000 a month. The company’s own infrastructure runs in AWS eu-central-1 in Frankfurt, Germany.
