Key Takeaways

Manual QA coverage increased from 4% of Arabic calls to 100% automated call assessment using accurate Arabic speech-to-text.

‍

Gulf Arabic transcription accuracy enabled reliable detection of compliance-critical phrases, improving automated QA scoring trustworthiness.

‍

Compliance teams reduced review workload by focusing only on flagged calls instead of randomly sampling recordings.

‍

Transcript search capabilities accelerated regulatory investigations and audit responses by eliminating hours of manual call listening.

‍

A UAE retail bank transformed Arabic call center QA by replacing manual sampling with full-call transcription using Munsit STT. Accurate Gulf dialect recognition enabled 100% QA coverage, stronger compliance oversight, faster investigations, and deeper visibility into customer service and regulatory risks.

‍

The Challenge

Quality assurance in a bank call center is both a compliance requirement and a commercial priority. Calls need to be checked for regulatory adherence, sales practice compliance, and service quality. For most UAE banks, that means monitoring a large volume of Arabic-language calls.
‍

This bank was manually reviewing roughly 4% of its Arabic call volume. Supervisors listened to recordings, scored them against a rubric, and escalated issues when they found them. The problem: 96% of calls produced no QA data at all. The compliance team was working from a sample too small to be reliable, and the commercial quality team had no way to know if service standards were being met across the full agent population.
‍

The bank had already tested one automated QA product built on a third-party Arabic ASR model. Transcription accuracy on the Gulf dialect was too low for the tool to work reliably. The scoring logic depended on detecting specific phrases; if the transcript missed or distorted those phrases, the automated score was wrong. The QA team didn't trust the output and continued relying on manual review.

This is some text inside of a div block.

Why Dialect Coverage Was the Core Problem

The bank's call center handled three main Arabic dialects: Gulf Arabic (from Emirati and GCC national customers), Levantine Arabic (from a large portion of the expatriate customer base), and Modern Standard Arabic (used by some agents in ambiguous dialect situations).
‍

The existing ASR system's weak spot was specifically Gulf Arabic. MSA and Levantine accuracy were acceptable; Gulf accuracy was not. This mattered because the most compliance-sensitive interactions, sales calls, fee disclosures, and complaint handling were skewed toward Gulf-national customers. In practice, the system was inadvertently better covered for the customer segment that was less commercially sensitive.
‍

Munsit STT's training on multi-dialect Arabic data, with specific coverage of Gulf spoken varieties, addressed this gap directly. Before committing to a full deployment, the bank tested Munsit on a sample of 500 calls across all three dialect types.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse varius enim in eros elementum tristique. Duis cursus, mi quis viverra ornare, eros dolor interdum nulla, ut commodo diam libero vitae erat. Aenean faucibus nibh et justo cursus id rutrum lorem imperdiet. Nunc ut sem vitae risus tristique posuere.

The Approach

The bank deployed Munsit STT as the transcription layer for all Arabic inbound call recordings. Call audio was routed through the Munsit API post-call, producing structured transcripts with speaker-turn labels within minutes of each call completing. Those transcripts were then passed into the bank's existing QA scoring tool, which had been rebuilt with updated phrase detection logic once accurate Arabic transcripts were available.
‍

The QA workflow shifted from random manual sampling to a hybrid model:
Automated scoring covered 100% of calls
Human review was reserved for calls that scored below the threshold on compliance criteria or contained specific flag phrases
Reviewer effort was concentrated on calls that actually warranted attention, not distributed randomly

The compliance team also used the transcript archive to respond to regulatory inquiries faster. Instead of pulling recordings and listening through them, they could search the transcript database and retrieve the relevant call in minutes.

What Changed

The most immediate shift was operational. Full-coverage automated QA replaced 4% manual sampling. Human review hours moved from routine scoring to genuine investigation of flagged calls. Agent coaching became more specific supervisors could point to exact transcript excerpts rather than recalled impressions from a recording they'd listened to once.
‍

Two commercial benefits emerged that hadn't been the primary goal:
‍

Missing fee disclosures: The bank identified a group of agents who were consistently not completing required fee disclosures on specific product calls. This had been invisible in the 4% sample. Catching it before a regulatory review was a significant risk reduction.
‍
Hidden complaint patterns: A product sold through the call center had a much higher complaint rate than internal reporting showed, because complaints were being logged inconsistently. The transcript data made the pattern visible for the first time.

The bank is now evaluating a second phase: using Munsit STT to feed a real-time coaching layer that surfaces guidance to agents during live calls, rather than only in post-call review.

Result

For banks operating in the UAE, Arabic call center QA built on generic ASR is structurally limited. Gulf dialect accuracy is what separates a compliance function that works from one that produces results too unreliable to act on.
‍

Dialect-specific accuracy isn't a nice-to-have; it's the foundation that automated QA scoring depends on
Full call coverage transforms compliance from a labor-intensive sampling exercise into a scalable data operation
The same transcript data that powers QA also accelerates regulatory response and surfaces commercial patterns that sampling misses.

Munsit STT provides the transcription quality needed to run automated Arabic call center QA at full volume, making compliance a system, not a sample.

Why Dialect Coverage Was the Core Problem

Understanding the origins of AI hallucinations is the first step toward mitigating them. The phenomenon is not a single problem but rather a complex issue with multiple contributing factors.

Training Data Deficiencies

The most significant contributor to AI hallucinations is the data on which the models are trained. LLMs learn from vast datasets scraped from the internet, which contain a mixture of factual information, opinions, misinformation, and biases. Several specific data-related issues can lead to hallucinations:
