Built to run with your stack
Agent accelerator
Not every turn needs your LLM
Fewer model calls per conversation.
Simple turns
Confirmations, greetings, consent speech, hold responses handled locally.
Complex turns
Reasoning, decision-making, ambiguous input go to your model as normal.
The result
Fewer LLM calls. Lower cost. Same output quality.
Healthcare voice agents running on SLNG
Patient voice data stays in-region. HIPAA compliant by architecture.
Front-desk and scheduling
Appointment booking, rescheduling, eligibility checks, after-hours coverage, waitlist management. Voice agents that read and write to EHR and scheduling systems.
Revenue cycle
Eligibility verification, prior auth follow-up, claims status, denial outreach, patient billing reminders. Structured payer calls with outputs that write directly to RCM platforms.
Patient intake and triage
Symptom capture, pre-visit intake, nurse escalation, telehealth pre-screening, behavioral health intake. Structured clinical data for EHR entry before a clinician is involved.
Medical transcription
Clinical dictation, SOAP note generation, real-time scribing, specialty terminology handling, structured data extraction for billing and analytics. In-region processing.
Adaptive Execution layer
Keep your pipeline. Add the execution layer
The perfect execution path for every turn.
LLM routing
Per-turn model selection and cost optimization.
PII redaction
Personally identifiable data stripped before it leaves the hub.
TTS smart caching
Repeated TTS responses served from cache. Provider never gets called.
Compliance and security
Full-stack agent execution
30+ STT and TTS models, routing and caching underneath.

Is SLNG HIPAA compliant?
Yes. SLNG is HIPAA compliant with BAA available. ISO 27001 certified. SOC 2 Type II in audit. Details at trust.slng.ai.
Does SLNG work with my agent platform?
If it has a custom LLM field or accepts an OpenAI-compatible endpoint, yes. ElevenLabs, Deepgram, Vapi, Vocode, Bolna, Voiceflow confirmed.
How does latency improve?
Simple turns skip the LLM round-trip entirely. 39% less turn latency on average.
Is my data safe?
PII redaction built in. ISO 27001 certified. HIPAA compliant. GDPR compliant. SOC 2 Type II in audit.
Does my voice AI data stay in-region?
Yes. Audio processed in a region stays in that region. Data residency is enforced at the routing layer, not promised in documentation. Every call is logged with region, provider, model, and timestamp. SLNG is ISO 27001 certified, HIPAA compliant, and GDPR compliant.
How do I select a region?
One header: X-Region: ap-south-1. Add it to any API call. Same endpoint, same models, different physical location. No DNS changes, no separate deployments.
What does "per agent minute" mean?
Agent minute is the length of the call, not the amount of audio processed. A 3-minute call is 3 agent minutes regardless of how much silence or overlap it contains. SLNG bills per agent minute. Model providers typically bill per audio minute. SLNG simplifies this.
How do I integrate SLNG with my voice AI stack?
Swap your STT, LLM, and TTS endpoints to SLNG. Add one header (X-Region) to select your region. No changes to your orchestrator, your models, or your agent logic. Works with LiveKit, Pipecat, Cognigy, or any custom stack.
