What is SLNG?
SLNG is the first radically global infrastructure for speech AI. It integrates every model and every region with orchestrated compute and built-in compliance, enabling teams to build real-time, multilingual, and cost-effective voice products without lock-in.
How is SLNG different from other voice AI providers?
Most providers focus on a single voice model or API. SLNG is not another model — it’s the infrastructure that unifies them. We connect open-source and proprietary models, embed compliance by design, and deploy compute in 11+ regions, making voice AI simple, viable, and universal.
Does SLNG support languages and dialects beyond English?
Yes. SLNG supports a wide range of languages, dialects, and even professional slang. From Hindi and Arabic to Japanese and maritime or medical jargon, SLNG ensures your users are understood in their own voice, in real time.
How does SLNG handle compliance and data residency?
Compliance is built in. SLNG provides secure, region-aware infrastructure that aligns with local regulations by design. Audit trails, region locks, and sovereignty controls ensure your voice products stay compliant everywhere.
How much does SLNG cost?
SLNG offers transparent per-minute pricing with no hidden fees or minimums. You can set budget caps and monitor usage directly from the dashboard. Smart routing optimizes for latency and cost, making advanced voice AI economically viable for startups, enterprises, and regulated industries.
