Call Quality Scores

Every call receives an automated quality score that measures how well the technical components performed. This helps you identify and fix issues with call quality.

Overall Score

Each call gets a score from 0 to 100:

Score RangeRatingWhat It Means
80–100ExcellentEverything worked well
60–79GoodMinor issues that didn’t significantly affect the call
40–59FairNoticeable issues that may have affected the experience
0–39PoorSignificant problems occurred during the call

Component Scores

The overall score is made up of four component scores, each rated 0–100:

ComponentWhat It Measures
Speech Recognition (STT)How accurately the AI understood what the caller said
Response QualityHow appropriate and helpful the AI’s responses were
Tool ExecutionHow well tools performed (appointment booking, SMS, etc.)
Voice Synthesis (TTS)How natural and clear the AI’s voice sounded

Issue Detection

The quality system automatically flags problems:

Audio Issues

  • Background noise affecting speech recognition
  • Caller’s audio too quiet or distorted
  • Echo or feedback detected

Response Issues

  • AI response was too slow
  • Response didn’t match the caller’s question
  • AI repeated itself unnecessarily

Tool Failures

  • Failed to book an appointment
  • SMS failed to send
  • Calendar lookup timed out
  • CRM integration error

Long Silences

  • Unusual pauses during the conversation
  • Delays between the caller speaking and the AI responding

Problem Details

Each detected issue includes:

  • Severity — HIGH, MEDIUM, or LOW
  • Description — What happened
  • When — At what point in the call it occurred

Focus on HIGH severity issues first. These are problems that likely affected the caller’s experience.

Where to Find Quality Scores

  3. Analytics — View average quality scores over time in your analytics dashboard

Using Quality Scores

Identify Recurring Issues

If you see patterns:

  • Low STT scores → Check if callers are calling from noisy environments, or if your agent’s language settings match your callers
  • Low Response scores → Review your agent’s instructions and FAQs — it may need more information
  • Low Tool scores → Check your integration connections and make sure they’re properly configured
  • Low TTS scores → Try a different voice or adjust speaking speed

Filter Problem Calls

Use the quality filters to find calls with specific issues:

  • Calls with audio issues
  • Calls with tool failures
  • Calls with response issues
  • Calls with long silences

This helps you quickly find and investigate problem calls instead of reviewing every call manually.
