Sound is our medium
Voice is crossing a threshold. It is no longer a feature but core infrastructure. And unlike text or UI, voice offers no retries. When a system mishears once, trust is lost immediately.
ai-coustics exists to fix the part of Voice AI that usually breaks first: audio reliability.
We build the audio intelligence layer between real-world sound and machine understanding. Our SDK and APIs turn raw, unpredictable audio into stable, machine-ready input for Voice AI systems, running directly on-device with sub-40 ms latency.
We are audio native. Our team brings together deep experience in signal processing, acoustics, and applied machine learning, with a practical focus on how sound behaves in real environments and how machines actually interpret speech.
From real-time agents and telephony to transcription and conversational systems, ai-coustics helps teams build Voice AI that works reliably in production, not just in ideal conditions.
Backed by Connect Ventures, Partech, and Inovia Capital, we are building the infrastructure Voice AI depends on as voice becomes required, not optional.
