Conversation intelligence

The transcription layer behind contact center analytics

In contact center analytics, transcript errors don't stay put. A wrong entity skews a trend, a misattributed line skews sentiment, and clients notice months later.

Why teams switch to Gladia

Your insights are only as good as the transcripts they're built on

Every topic trend, sentiment signal, and coaching insight your platform sells starts with a transcript, and Gladia's contact center speech-to-text is built for the accuracy that chain depends on.

Entity accuracy

Errors don't stay where they start

A wrong product name corrupts a trend. A misheard number breaks a dashboard. Gladia leads Earnings22, the benchmark built on names and numbers.

  • Named entity recognition
  • Custom vocabulary for brands & products
  • #1 on Earnings22
Full coverage

Trends only show up at full volume

Topic shifts and product feedback hide in a 1–5% sample. Fast async processing makes analyzing every interaction practical, with calls ready the same day.

  • 100% interaction coverage
  • Fast async at volume
  • Same-day availability
Speaker attribution

Know whose words drive the outcome

Sentiment, talk ratios, and outcome signals only mean something when they're attributed to the right speaker. Gladia labels every word, agent or customer.

  • Word-level speaker labels
  • Per-speaker sentiment
  • #1 on DIHARD III
Multilingual

No market blind spots

One underperforming language leaves a gap in every dashboard for that market. Gladia covers 100+ languages and translates them into one reporting language.

  • 100+ languages
  • Translation for unified reporting
  • Mid-call code-switching
Human & AI agents

One schema for every agent on the floor

AI agents now handle calls alongside humans. Gladia transcribes both through the same API and output schema, so your analytics cover every interaction.

  • Same output schema
  • One integration
  • Ready for hybrid contact centers
Benchmarks

Entity accuracy, tested against the field

Generic WER hides the errors analytics can't afford: company names, products, figures. Earnings22 is the toughest public benchmark for entity-dense speech, and Solaria-3 is the only model under 7% WER. Lower is better. Our benchmark methodology is open-source.
