01 · Use cases

One agent, many phone lines.

Drop Lumera in front of any number. It picks the right script per line and stays in character across the whole call.

Scheduling

Books, reschedules and confirms appointments straight into Google Calendar or your booking system — reading real availability, not guessing.

Support triage

Resolves password resets, order status and FAQ in voice, then opens a ticket with a clean summary for anything it escalates.

Inbound reception

A 24/7 front desk that greets callers by name when it knows them, routes by intent, and never puts anyone on hold.

Outbound reminders

Confirmation and no-show reminder calls that adapt to the reply — "running late" becomes a reschedule, not a dead end.

02 · Voice quality

Engineered to sound calm.

Latency is the difference between a conversation and an interrogation. Lumera is tuned end-to-end so callers stop noticing it's an agent.

380ms Median turn latency

Speech-in to speech-out, including barge-in handling. Below the threshold where people start talking over each other.

4.6/5 Naturalness MOS

Blind mean-opinion-score across 2,100 raters who didn't know which calls were human. Most couldn't tell.

22kHz Neural TTS sample rate

Full-band synthesis with breath, prosody and back-channel cues — "mm-hm", soft pauses, real intonation.

99.95% Uptime, trailing 90d

Carrier-grade redundancy across three regions. Calls fail over without a dropped word.

03 · Sample call

A real booking, end to end.

Inbound call to a dental clinic. Lumera checks the calendar, offers slots, and confirms — typed out live below.

Lumera Thanks for calling Brightline Dental — this is the front desk. How can I help?
Caller Hi, I think I'm overdue for a cleaning. Can I book one?
Lumera Of course. I've got Thursday at 2:15 or Friday morning at 9:40 — which works better?
Caller Friday morning's perfect.
Lumera Booked — Friday 9:40 with Dr. Okafor. I'll text a confirmation now. Anything else?

04 · Integrations
