Interesting topic. I’m going to test gpt-realtime-mini-2025-10-06 in Portuguese as well.
We are currently using gpt-realtime-mini, but the quality has been quite poor for Portuguese voice agents. We are seeing issues with context loss, weaker understanding, and overall lower reliability in real customer scenarios.
This is directly affecting our ability to expand the project to more customers and use cases. The standard gpt-realtime model performs better, but it is too expensive for our use case and not economically viable at scale.
It would be very helpful to understand whether gpt-realtime-mini-2025-10-06 is expected to improve non-English voice quality, especially for Portuguese, or if there are recommended settings to reduce these issues.
