Why teams switch to Gladia

Accurate enough to score every call. Fast enough to review them the same day.

The accuracy ceiling of your STT layer is the accuracy ceiling of every QA score, compliance flag, and coaching note built on top of it.

Keyword accuracy

Keyword accuracy, not overall WER

Most STT providers benchmark on aggregate WER. Your QA scorecard depends on whether the right specific words landed – compliance phrases, account numbers, required disclosures. Gladia is built for keyword-level accuracy, not the metric that looks good in a benchmark.

  • Low keyword error rate on structured entities
  • Named entity recognition
  • Compliance phrase accuracy on noisy telephony audio
  • Account numbers, contract IDs, and contact data captured correctly
Full coverage

Score every call, not a 1–5% sample

Manual QA programs review a fraction of calls because the economics of their transcription layer made full coverage impossible. Gladia's async pipeline is priced and built for scoring every interaction your contact center produces, same-day.

  • Priced for full-volume async
  • Same-day call availability for QA review
  • All QA features (diarization, sentiment, NER, keyword flagging)
  • No manual sampling ceiling
Diarization

Agent vs. customer, correctly attributed

Every QA output – talk ratios, per-agent sentiment, compliance attribution – depends on correctly knowing who said what. Gladia delivers 3x fewer diarization errors on real telephony audio, with dual-channel accuracy your scorecards can build on.

  • 3x fewer diarization errors
  • Dual-channel diarization built for 8kHz telephony
  • Per-speaker sentiment and talk ratios
  • No per-channel billing surcharge
Structured output

Structured output your QA pipeline can use directly

Gladia returns speaker-labeled transcripts with sentiment scores and named entities — structured for your QA scorecard or compliance dashboard without custom parsing or transcript cleanup.

  • Utterance-level sentiment
  • Named entity recognition
  • Structured output, QA-pipeline-ready
  • No separate NLP layer required
Real-time roadmap

Add real-time coaching without switching providers

Start with async post-call QA. Add real-time coaching triggers, compliance alerts, or keyword detection mid-call later. Same API, same schema, no second provider.

  • ~300ms streaming for live coaching
  • Same output schema as async
  • Real-time keyword detection and compliance alerts
  • No second provider needed

CCaaS case study
Automated
Quality monitoring
Call transcripts matched against internal compliance scripts automatically. Agents validate findings instead of reviewing recordings manually.
200+
Sales agents monitored
Thousands of inbound calls processed daily across France, every one available for QA review, not just the fraction a manual team could reach.
Deeper
Call insights
Topics, sentiments, and agent performance extracted from every interaction, not inferred from a manually sampled subset.
Challenge

Every compliance check meant downloading a call and searching the transcript by hand

Selectra's QA team was reviewing recordings one by one, manually scanning transcripts for compliance words and phrases across 200+ sales agents handling thousands of daily inbound calls. The process couldn't scale and the calls that didn't get reviewed were blind spots.
