TTS for fraud-alert and verification calls.
A fraud alert is the one outbound call a customer wants to receive — and it has to happen within seconds of the flag, sound calm, and prove it came from you. This page works the latency, the spike shape, and the provenance story.
01
What the call has to do
- Reach the cardholder while the transaction is still pending — synthesis latency cannot be the bottleneck.
- Read card endings, amounts, and merchant names precisely — transcript controls pin pronunciation and pacing.
- Sound like the bank every time: one cloned identity, watermarked on every sample, on every serving tier.
02
The incident spike
Fraud comes in bursts — a breach at a merchant means ten thousand calls in an hour, then quiet. Burst lines exist for exactly this: your standing fleet handles the daily trickle, and the spike spills to burst at $10 a line-day instead of an overage bill with a comma in it.
03
The provenance story
Every synthesized sample carries an inaudible watermark, so a recording claimed to be your bank’s voice can be checked against the signature. In a category where voice fraud is the threat, being the caller who can prove themselves is not optional — the provenance sheet publishes how it works.
