From Missed Call to Booked Client - in Seconds
We've combined world-class speech recognition, large language models, and neural voice synthesis into one seamless platform built for service businesses.
How every call gets handled
Five steps, sub-second latency, zero missed opportunities.
Smart Call Forwarding
Set up conditional forwarding from your business line. When you don't answer within a few rings - or your line is busy - the call is instantly routed to your SentraVoice agent. No app, no hardware.
Real-Time Speech Processing
As the customer speaks, our pipeline converts audio to text with sub-100ms latency. Background noise, accents, and natural interruptions are all handled gracefully.
Contextual Intelligence
Our LLM analyzes caller intent, references your business instructions, and decides the best path - whether that's qualifying a lead, answering a question, or pulling up availability.
Neural Voice Response
The agent responds in a warm, professional voice that sounds indistinguishable from a human receptionist - maintaining your brand's tone and prestige on every call.
Instant Action & Notification
The call ends with a confirmed appointment and an instant summary sent to your phone via SMS and email. No manual data entry, no follow-up slip-throughs.
