Detect complaints in calls

Detect complaints in calls with Stentor: a practical, on-prem approach built for Azerbaijani teams.

Automated Complaint Detection Across Every Call

Customer complaints buried in call recordings often cost teams valuable time, damage long-term relationships, and create significant compliance exposure. Traditional manual sampling only catches a fraction of these issues, leaving the majority of customer friction invisible. Stentor, developed by Allmaz, eliminates these blind spots by analysing 100% of your calls. By transcribing, diarising, and scoring every single conversation, the system surfaces complaints, negative sentiment, and compliance risks in real-time, allowing your team to intervene before issues escalate. Engineered specifically for the linguistic nuances of the region, Stentor features a purpose-built Azerbaijani speech-to-text engine that seamlessly handles mixed Azerbaijani and Russian conversations. To ensure maximum security and regulatory adherence, the platform operates within a single-tenant private cloud. This architecture guarantees that your sensitive voice data and transcripts never leave your controlled environment, providing a secure foundation for comprehensive quality assurance.

How Stentor Detects and Surfaces Complaints

100% Call Analysis

Every recorded call is processed — no sampling thresholds, no missed interactions. Complaints that would have slipped through a manual review cycle are captured consistently.

Transcription and Speaker Diarisation

Stentor transcribes each call and separates agent and customer speech, making it straightforward to pinpoint exactly who said what and when a complaint moment occurred.

Azerbaijani-First Speech Recognition

The speech-to-text engine is purpose-built for Azerbaijani and handles code-switching between Azerbaijani and Russian — a practical necessity for teams operating in Azerbaijan.

Complaint and Sentiment Detection

Negative sentiment signals and explicit complaint language are detected at the utterance level, giving supervisors a clear, timestamped view of where conversations turned difficult.

Hybrid QA Scoring

Scoring combines rule-based checks, semantic AI evaluation, and human override capability. Teams can enforce specific compliance rules while still benefiting from AI-driven nuance detection.

Private Cloud Deployment

Stentor runs in a single-tenant private cloud. Call audio, transcripts, and scores remain within your infrastructure — no third-party data sharing required.

From Call Recording to Complaint Alert in Four Steps

Frequently Asked Questions

Does Stentor really analyse every call, or is there a practical limit?

Stentor is designed to process 100% of recorded calls without sampling caps. The system is built to scale according to your specific call volume within your dedicated private cloud deployment.

How does Stentor handle conversations that switch between Azerbaijani and Russian?

The speech-to-text engine is purpose-built for the Azerbaijani market, meaning it can accurately transcribe mixed Azerbaijani and Russian speech within a single interaction, reflecting real-world language patterns.

What happens when the AI score does not match a reviewer's judgement?

Stentor utilizes a hybrid scoring model that supports human override. QA reviewers can manually adjust or replace any AI-generated score, ensuring that human expertise remains the final authority in the quality process.

Where is our call data stored, and who can access it?

All data is stored in a single-tenant private cloud. Your audio files, transcripts, and scores remain within your own environment and are never shared with or accessible by other tenants or external parties.

Can we define our own complaint or compliance rules in addition to the AI detection?

Yes. The hybrid QA scoring model includes a configurable rule-based layer. This allows your team to set specific compliance requirements or internal quality standards that work alongside the semantic AI detection.
