Call-center speech analytics

You review 3% of calls. Stentor reviews all.

An AI-powered call-center analytics platform that transcribes, scores quality, and detects complaints and risk across 100% of your conversations — in your own private cloud.

The problem

Why Stentor exists

97%
Calls never reviewed

Manual QA can only sample 1–3% of conversations; the rest are invisible.

Unheard
Undetected complaints

Complaints, churn signals and compliance breaches slip through unheard.

Weeks behind
Slow, subjective QA

Spreadsheet scoring is sample-biased, inconsistent and weeks behind.

AZ / RU
Language gap

Global speech tools handle Azerbaijani and mixed AZ/RU conversations poorly.

Stentor

Στέντωρ
The name

Where the name comes from

In Homer’s Iliad, Stentor was the herald of the Greek army — a man whose voice, the poet wrote, was as loud as fifty other men combined, so nothing said on the field escaped him. His name gave English the word "stentorian". We borrowed it for a platform built on the same promise: every voice in your call center heard, every conversation counted, nothing lost in the noise.

Deployment & trust

Yours to control

Stentor runs as a single-tenant private cloud — no data egress, no shared tenancy. Purpose-built for banks, government hotlines, insurance, telecom and healthcare where conversations can never leave the building.
