I am providing the technical details and logs from our Unreal Engine environment to help you investigate the instability.

Character ID: a82b6c24-f5b8-11f0-b4e2-42010a7be027 Session ID: b14a70439d338a7c6df23aa0b2e4e7a3

We have identified a specific recurring error in our logs that appears to be triggering the response failure:

Error Message: Get Response Failed name 'stt_start_time' is not defined Error Code: 13

This internal variable error (stt_start_time) suggests a breakdown in the speech-to-text timing or response handling within the Convai API. I have attached the full Unreal Engine log files to this email for your team to trace.

Welcome to the Convai Developer Forum!

Sorry for the trouble you’ve been facing. The issue related to stt_start_time was fixed last Friday. The logs you attached are from about 4 days ago.

Please try again now with a fresh session and let us know if the problem persists. If it does, share the latest logs and timestamps so we can recheck.

Thank you for the update. We are experiencing significant delays in receiving audio when using ElevenLabs custom voices within Convai. The wait time is currently unacceptable for a real-time conversational AI experience. Is this a known bottleneck in the Convai-ElevenLabs integration, and what is the roadmap for reducing this latency?

Could you please share a video and logs?
