"Voice output stopped working after VAPI update - GPT-4o Mini Realtime + Chinese prompts"
Hello VAPI community!
I'm experiencing an issue where my voice assistant has stopped producing audio output after a recent VAPI platform update. The same configuration was working perfectly before.
Current Setup:
Model: OpenAI GPT-4o Mini Realtime Cluster
Voice Provider: OpenAI
Voice: Echo
TTS Model: GPT-4o mini tts
Language: Chinese prompts/responses
Problem:
Previously: Everything worked normally with voice output
After VAPI update: No voice output during testing (assistant responds but silent)
OpenAI credits: Sufficient balance confirmed
What I've tried:
Verified OpenAI account has adequate credits
Confirmed same settings that previously worked

Thank you for sharing your setup and troubleshooting steps. Since recent updates changed voice compatibility and model support, could you please confirm if switching to one of the newly supported voices (such as "ash", "ballad", "coral", "sage", or "verse") with your current model restores voice output? This will help determine if the issue is specific to the "Echo" voice after the update.
Tip: The latest documentation notes expanded voice compatibility for realtime models, so testing with a different supported voice may clarify if the problem is voice-specific or model-related.

To help track down this issue, could you share one or two:
- The call ID
- When exactly this happened (the timestamp)
- What response you expected to get
- What response you actually got instead
This would really help us figure out what went wrong!
