Hello everyone, I’m having an issue with the speech quality of my voice agent. Sometimes, during a call, the agent sounds bad — robotic, choppy, or unclear. Other times it works fine. I suspect it might be related to the network, but I’m not sure how to properly troubleshoot or fix it. Some details: I’m using an AWS Lambda function to invoke the agent. When I listen to the recording of the session afterwards, it sounds clear and without errors. However, during the live call on my phone, it sometimes sounds bad. I also tried with other phones and networks — sometimes it sounds good, sometimes bad. I thought it could be my network signal, but the behavior doesn’t seem consistent. I’m using a Spanish voice, and I also tried switching to another Spanish voice, but the problem still happens. Could this issue be caused by my network connection or the caller’s network? Or could it be related to the voice configuration settings? Is there anything specific I should check or adjust in my Lambda or agent setup to improve the audio quality during live calls? Any guidance would be much appreciated.

Hi, could you please provide a call id where you experienced this issue? We would like to review the logs to identify the cause.
