“We're not just building another voice AI platform, we are rethinking the entire ecosystem to be developer first, truly global and compliant."

SLNG tackles the key limitations of today’s voice AI infrastructure. Most platforms prioritize major languages like English, Spanish, and French, leaving others underserved. High latency, data residency restrictions, and single-provider lock-ins hinder global deployment, especially in regulated industries.

SLNG’s model-agnostic platform lets developers integrate any speech-to-text, text-to-speech, or voice cloning model via a single API. Its regional infrastructure ensures low latency and full compliance, enabling truly global deployment.

With an open ecosystem, developers can mix open-source and proprietary models without vendor lock-in. SDKs and APIs are designed for fast integration, cutting implementation times from months to days.

Currently, SLNG supports deployment across 20+ regions, allowing companies in healthcare, finance, and government to launch voice AI while fully meeting data residency and regulatory requirements.

“What excites us about SLNG is the audacity of their mission: to make voice AI universal, compliant, and developer-first from day one. Luke and the team are not just building a product - they’re building the missing infrastructure for a truly global voice ecosystem. We believe SLNG can define the next era of speech technology, “ added Akash Bajwa, Principal at Earlybird VC.
