Hi there! I understand you're experiencing a critical issue where voice inputs appear in your logs but aren't actually spoken by the assistant. This is definitely frustrating! 👋
I can't diagnose the exact cause of your specific Call ID without further investigation, but I can definitely help with troubleshooting steps for this type of issue.
Based on the information I've found, here are several potential causes and solutions for missing voice input in Vapi:
### Voice ID and Configuration Issues
One common cause is incorrect voice ID configuration. According to [Discord discussions](

### Voice Pipeline Configuration
Check your voice pipeline configuration, particularly:
- **startSpeakingPlan configuration**: Incorrect settings here can cause voice input issues according to [user reports](

- **Voice file path**: An incorrect or misspelled voice file path can prevent the system from finding the voice file ([Discord thread](

### Transcriber Issues
There might be a "deafness bug" related to issues with the transcriber (e.g., Deepgram). According to [user discussions](
