Platform • Architecture

bolt Direct Voice & Telecom Pipeline

Respond in under 900ms with a streaming-first voice pipeline.

Engineered on a streaming-first audio pipeline that processes speech in real time as the caller talks—rather than waiting for full sentences to finish. Direct WebRTC voice sessions respond in under 900ms (~880ms average), while dedicated PSTN phone lines pair that same engine with standard telecom carrier routing.

Streaming Audio

Parallel Opus audio, live STT, and first-token synthesis.

< 900ms Direct Voice

Sub-second turnaround on web & app voice streams.

Carrier PSTN Lines

Dedicated clinic numbers routed over telecom trunks.

Zero Buffering

Starts synthesizing voice on the first LLM token.

record_voice_over Adaptive Turn-Taking & VAD Engine

Handle mid-sentence interruptions naturally without talking over callers.

Callers don't speak in rigid scripts—they pause, change their minds, and interrupt mid-sentence. Aura AI monitors inbound audio continuously with a 28ms Voice Activity Detection (VAD) loop, halting its own speech the instant a caller barges in and pivoting seamlessly to the new question.

28ms Barge-In Cut

Instantly halts agent speech the moment a caller speaks.

Immediate Context Pivot

Answers the new question while retaining call state.

Full-Duplex Echo Guard

Zero self-interruption or robotic audio clipping.

Natural Prosody

Warm, unhurried vocal pacing for patient trust.

Verified Passage Citation

Quotes exact fees, Sunday timings, and prep rules.

How It Works

From silence to speech in minutes.

Deploy production-ready voice agents in minutes, then customize every interaction as you scale.

1. Give your agent context STEP 01

Define your agent's role, tone of voice, and clinic workflows in plain natural language—no flowcharts or complex code required.

  • • Custom Persona: Greeting script, empathy tone & escalation boundaries.
  • • Intake Rules: Required patient details before confirming slots.
2. Upload knowledge base STEP 02

Drop in your clinic PDFs, treatment pricing sheets, and pre-visit prep guides so the agent answers from verified ground-truth files.

  • • Source-Grounded RAG: Vectors index your exact fee schedules & policies.
  • • Safe Fallbacks: Politely routes unlisted clinical queries to staff.
3. Telephony & WhatsApp STEP 03

Provision a dedicated clinic phone line or forward your existing reception number, and link your existing WhatsApp Business account.

  • • Voice & Carrier Lines: Sub-900ms WebRTC voice & standard PSTN routing.
  • • Coexistence for WhatsApp: Targets <10s replies under optimal conditions.
4. Go live & monitor STEP 04

Track every inbound call, WhatsApp thread, and booked appointment from a unified live dashboard with full audio and text logs.

  • • Full Audit Trail: Review call recordings, transcripts & RAG citations.
  • • 1-Click Takeover: Step into any WhatsApp chat from your phone anytime.
