“Unmuting the world”: Spain’s SLNG raises €3.3 million to challenge US-centric speech AI infrastructure
Summary
SLNG.ai raised €3.3 million in pre-seed funding to build a global speech AI infrastructure platform. The Barcelona startup wants to replace US-centric voice tooling with a model-agnostic API that supports multiple speech models and regional compliance. It targets developers, startups, and enterprises that need low-latency deployment across regulated and multilingual markets. The company already supports deployment in more than 20 regions and focuses on reducing vendor lock-in and data residency barriers. This round signals growing investor interest in foundational voice AI infrastructure across Europe.
