SLNG// FAQ

What is the core difference between SLNG and other voice AI providers?

SLNG functions as an infrastructure that unifies various voice AI models and regions, rather than being a single voice model itself. It integrates open-source and proprietary models, embeds compliance, and deploys compute across 11+ regions to make voice AI accessible and viable.

How does SLNG ensure compliance and data residency for voice AI applications?

SLNG has compliance built in by design, offering region-locked execution where inference runs only in approved regions like EU, US, or Germany. It provides explicit residency controls on every request and ensures that only approved zones and providers are used.

Can I use SLNG with both open-source and proprietary voice AI models?

Yes, SLNG's Voice AI Catalog integrates both open-source and proprietary models, allowing users to discover, compare, and deploy them through a unified interface and API without vendor lock-in.

How does SLNG's pricing model work, and are there any hidden fees?

SLNG uses transparent, per-minute usage-based pricing with no hidden fees or minimums. Users pay only for the voice workloads they run, and built-in cost caps and real-time dashboards help manage budgets.

What kind of support does SLNG offer for developers?

SLNG provides a universal API for STT, TTS, diarization, and voice cloning, along with SDKs and starter kits for Python, Node, Go, and other languages. It also offers JSON in/out and webhooks for seamless integration.
