Summary
👤
Senior🎓
Top SchoolAlexandre Caulier is a machine learning and speech AI leader with a decade of experience building production-ready, on-device and cloud-first voice systems; he co-founded and serves as CTO of Blynt AI to simplify contextual speech integration for companies. Previously a Senior Machine Learning Scientist and Engineering Manager at Sonos, he led teams that shipped embedded ASR, NLU, and wake-word models—pioneering domain adaptation techniques like shallow fusion and rescoring for better in-field performance. He cut his teeth at Snips optimizing real-time ASR for tiny devices and remains fluent across the stack from Python model training to Rust inference. Based in Chambéry, France, he blends hands-on research, mentoring and product leadership, and is particularly skilled at turning language-model advances into deployable, low-latency solutions. An underappreciated strength is his knack for shrinking complex ASR pipelines to run efficiently on constrained hardware without sacrificing accuracy.
