VAPI Voice randomly sounds robotic or distorted during some calls
Hi team,
We’re using Vapi Voices as the TTS for our Voice AI Agent in production, and we’ve noticed a random issue where the voice suddenly sounds robotic or distorted during some calls. It typically returns to normal speech on the next dialogue turn.
The issue occurs sporadically, not on every call and we haven’t identified a consistent pattern or trigger.
For easier troubleshooting, I’m including the following details:
Call ID: 019a2bb6-a9eb-744a-96df-13fc7a6e0acb
Timestamp: 00:20
Could you please help us understand what might be causing this?
Any suggestions on how to debug it or which logs/metrics to check would be greatly appreciated.
Thanks in advance for your help

To start troubleshooting the robotic or distorted voice issue, check the call logs for your provided Call ID and timestamp in the Vapi Dashboard:
1. Go to
Observe > Call Logs in your Vapi Dashboard.
2. Locate call ID 019a2bb6-a9eb-744a-96df-13fc7a6e0acb and review the logs around timestamp 00:20 for any errors or warnings.
This will help you identify if there are any TTS errors, latency spikes, or audio format issues at the moment the distortion occurs.
