Gandr for enterprise fleets.

An enterprise voice bill on a character meter is a forecast that has to be re-approved every quarter. A fleet of flat lines is a number that survives the fiscal year: lines × $150, whatever your callers say. Every claim on this sheet is published elsewhere on this site with its measurement basis stated.

× $150

the whole budget line — headcount arithmetic, not usage forecasting

What signs off in one meeting

The bill is lines × rate — finance models it in one cell, and doubling call volume changes nothing on the invoice.
Latency is published as percentile pairs with the harness stated, and the pair holds on every line in the fleet.
Every synthesized sample carries an inaudible watermark, and customer reference audio never enters a training set.
Standby failover lines idle beside your current vendor at $20 a month — adoption can start as insurance.

A fleet, priced

Every meter cell is minutes × 1,000 characters × the published $30–$100 per-million range. The Gandr column is line count × $150 — check any row by hand.

Fleet	Minutes / mo	On a $30–$100 meter	On Gandr lines
20 lines, 24/7	864,000	$25,920 – $86,400	$3,000
50 lines, business hours	540,000	$16,200 – $54,000	$7,500
100 lines, 24/7	4,320,000	$129,600 – $432,000	$15,000

The posture behind the price

Three serving tiers stand behind one endpoint: the GPU fleet, a warm spill, and an independent fallback — a full outage costs latency, not availability. Past absolute capacity the API refuses fast with a retryable 503 instead of degrading a live call. The reliability sheet publishes the whole posture; the provenance sheet covers watermarking and data handling.

Serving that degrades before it fails

Three serving tiers behind one endpoint — primary GPU fleet, warm spill, independent fallback — and a fast retryable 503 past absolute capacity.

Provenance and privacy, applied at generation

The policy surface of the engine: an inaudible watermark on every sample, reference audio that never trains, and per-key audit trails at GET /v1/usage.

Standby lines for the vendor’s bad night

Standby failover lines run beside your current TTS provider for $20 a month each and activate automatically when it goes dark. Capacity insurance, priced.

Thirty minutes on your own numbers — fleet size, talk time, and the bill both ways, worked live.
