### Answer Issues with broken sound at the beginning of conversations can often be related to the audio models or settings used in the call. If you're experiencing this regularly, you might want to check several possible causes: 1. **Voice Provider Issues**: Sometimes, the voice provider might be experiencing issues which could affect sound quality. Verifying the status of the voice provider you are using could provide insights [(1)]() . 2. **Endpointing and Audio Models**: In Vapi, endpointing determines when a user has finished speaking to avoid cutting them off. If this model isn't calibrated correctly or is lagging due to technical issues, it might cause broken or incomplete sound as it struggles to correctly identify the end of the user's speech [(2)]() . 3. **Background Noise and Filtering**: If there's significant background noise, Vapi’s background noise filtering should help, but excessive noise can still cause issues with voice clarity. Ensuring a relatively quiet environment might help reduce this problem. 4. **Network Issues**: Poor network conditions can also lead to broken sounds. Ensuring a stable and fast internet connection might mitigate these issues. If these general checks don't resolve the issue, it could be beneficial to look into the specific configurations or logs for the calls to further diagnose the problem.
