How do I troubleshoot AI agent call quality?

Last updated: November 5, 2026

Troubleshoot AI agent call quality by reviewing recent calls, identifying whether the issue is transcription, audio clarity, voice output, interruption handling, or timing, and then adjusting the relevant call settings.

Before you start

  • Review at least one recent call recording and transcript.

  • Confirm which agent and version handled the call.

  • Prepare examples of the exact call quality issue you want to improve.

Steps

  1. Open the AI agent.

  2. Go to the Calls tab.

  3. Open a recent call that shows the quality issue.

  4. Review the call transcript and recording.

  5. Identify whether the issue is audio clarity, transcription accuracy, spoken voice quality, interruptions, or overlapping speech.

  6. Check the agent’s speech-to-text mode.

  7. Review denoising settings and enable the appropriate noise reduction option if needed.

  8. Check voice temperature and voice speed.

  9. Add boosted keywords for important names, product terms, or industry phrases.

  10. Add pronunciation entries for terms the agent mispronounces.

  11. Adjust responsiveness or interruption sensitivity if the agent cuts off callers or overlaps with them.

  12. Use phone preview to test the updated settings.

  13. Review new calls after the change to confirm quality improves consistently.

Tips

  • Use accuracy-focused speech-to-text for technical or detail-heavy calls.

  • Enable stronger denoising for noisy call environments.

  • Keep voice speed near a natural speaking pace.

  • Disable ambient sound when clarity matters more than realism.

  • Change one setting at a time so you can isolate what improves quality.

Troubleshooting

  • The agent mishears callers: Switch speech-to-text to accuracy mode and enable denoising.

  • The agent sounds robotic: Adjust voice temperature or reduce voice speed.

  • Background noise affects calls: Enable noise cancellation or stronger denoising.

  • The agent cuts off mid-sentence: Lower interruption sensitivity.

  • The caller and agent overlap: Reduce responsiveness slightly.

  • Key phrases transcribe incorrectly: Add boosted keywords or pronunciation entries.
