If you try to use the Realtime API in the Playground in Safari on iOS, there is an ephemeral issue where the assistant will respond to itself.
I believe this means there is a problem with echo cancellation where it can actually hear its own output via the speaker input.
I’m not sure if this is an OpenAI bug or a Safari/iOS bug, but it’s not just in the playground - it also happens if you set up your own client webpage.
It doesn’t happen every single time. It probably happens about 25% of the time for me. When it does, the assistant can talk to itself for 4-6 messages, cutting itself off after a couple of words due to VAD.
It is also most likely to happen at the beginning of a conversation in my experience. Once the conversation is underway, this very rarely happens for me.
