# Call quality assurance and sentiment (voice QA)

Category: Speech recognition, intelligent OCR and voice-driven processes


Automatic audit of every support and sales call: pitch, volume and tempo reveal frustration and trigger an alert to the team lead or flag the call for urgent callback; promises that deviate from contract terms are caught (compliance check); in high-security cases the caller's voice pattern is compared to prevent fraud.

## How it works

1. Every call transcribed and scored
2. Frustration and compliance alerts
3. Voice verification where needed
