Why does my AI sound robotic?
You're using the default TTS voice. Upgrade to premium TTS (ElevenLabs) for $0.02-$0.04/min extra. Dramatically improves caller experience.
Why is my AI giving wrong information?
Your knowledge base has gaps. Review call transcripts to find unanswered questions, add them to your FAQ document.
Why are callers hanging up on my AI?
Likely causes: long greeting, rambling responses, no clear "how can I help" prompt. Review call recordings and shorten the AI's responses.
Why is my AI transferring too many calls?
Your confidence threshold may be too high. Lower it so the AI attempts more calls before transferring. Or improve the knowledge base so AI has more answers.
Why is my AI not transferring enough calls?
Your confidence threshold may be too low. The AI is attempting calls it can't handle. Raise the threshold so complex calls transfer to humans.
Why is latency so high?
Several causes: slow LLM, slow TTS, network issues. Try a faster LLM (GPT-4o vs GPT-4), use streaming TTS, check your network.
Why won't my AI interrupt correctly?
Interruption handling varies by platform. Retell AI handles it best. Vapi and Synthflow may need configuration. Test with role-play scenarios.
Why isn't my CRM integration working?
Check OAuth tokens (may have expired), Zapier/Make.com bridges (may be down), field mappings (may be incorrect). Test with a sample call and verify contact appears in CRM.
Why are my costs higher than expected?
Likely causes: premium TTS, LLM token pass-through, volume overage, additional phone numbers. Review your monthly invoice line by line.
How do I know if my AI is performing well?
Track 12 metrics: resolution rate (70-85%), escalation rate (10-15%), call duration (60-180 sec), caller satisfaction (4.5/5+). See our analytics guide.
