Under the Hood

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.

The Process

How every call gets handled

Five steps, sub-second latency, zero missed opportunities.

1
Setup

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.

2
Listening

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.

3
Reasoning

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.

4
Response

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.

5
Follow-Through

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.
