🌍 Accent Detection

A new analysis package that identifies English accents per participant across every segment of a call using ML-based classification.

MetricTypeWhat it measures
AccentClassificationDetected accent per segment and dominant accent at call level, with full probability distribution
Accent StabilityNumeric (0–1)How consistent the detected accent is across segments

Highlights:

  • Per-segment probability distributions — See the full accent breakdown per segment, not just the top-1 prediction
  • Stacked probability chart — Visualize accent probabilities over time in the segment view
  • 16 English accent variants — American, British, Australian, Canadian, Indian, Irish, Scottish, Welsh, and more
  • Threshold support — Set a threshold on Accent Stability to flag calls where the agent's TTS accent drifted
