ai-coustics is a Berlin-based deep-tech company building the audio intelligence layer for Voice AI. Founded in 2022 by researchers in audio, acoustics, and machine learning, the company focuses on the fundamental reliability problem that causes voice systems to fail outside controlled environments. Rather than competing with ASR, LLMs, or TTS, ai-coustics makes them reliable across all languages. Its SDK and model infrastructure sit at the boundary between real-world sound and machine understanding, conditioning raw audio into stable, machine-ready input optimized for downstream behavior. The company’s Quail model family delivers real-time speech enhancement, speaker isolation, and voice activity detection designed specifically for production of Voice AI. The Sparrow family, on the other hand, cleans up audio for human-to-human use cases as it's optimized for perceptual quality. ai-coustics powers voice agents, transcription pipelines, and telephony systems used by customers across Europe and North America, including LiveKit, Phonely, and Upstart. Backed by Connect Ventures, Partech, Inovia Capital, and angel investors from DeepMind, Hugging Face, and Amazon, the company is building a category-defining standard for Voice AI reliability. ai-coustics' mission is to make audio input reliable, measurable, and easy to deploy, so voice systems can operate with confidence in the environments where real people actually speak.
