  "textContent": "Since April 18th, and still happening as of April 26th, we’re intermittently seeing pretty big delays between the model finishing its spoken response and us receiving the `output_audio_buffer.stopped` websocket event.\n\nMost responses are fine, but suddenly a 2-4s audio response ends up with a 10-12s time window between `output_audio_buffer.started` and `output_audio_buffer.stopped`; meaning a 6-10s delay between the model finishing speech and the “stopped” event arriving.\n\nSince the `interrupt_response` setting doesn’t seem to have any effect, as flagged here months ago: https://community.openai.com/t/issues-with-realtime-turn-taking/1369161\n\nWe rely on switching `turn_detection` on/off with a `session.update` to avoid the model getting interrupted mid-speech. We disable turn detection after `response.create`, then re-enable it once we receive `output_audio_buffer.stopped`.\n\nWhen received promptly (as it always had been up until Apr 18th), the setup works well. However, when delayed, turn detection stays off way longer than it should. Therefore, the user speaks but their input is not picked up. Some go “hello? hello?”, while most just stay silent and hang up after a while. A very bad experience.\n\nExamples of big `output_audio_buffer.started` - `output_audio_buffer.stopped` windows below. Again, all these were concise 2-4s audio responses.\n\nresp_DVzNkceePLK27xkZ33UjJ\n\nresp_DY845PNK8S1rPRY4jYs3G\n\nresp_DYBAMoHOppd5Cx9UmKOj4\n\nresp_DYC3eWgge9qEhZulRXsXY\n\nresp_DYofSJBkOPKPkcNVDdcbg\n\nresp_DYofw8GNnuMhypBEo8rMy\n\nresp_DYohNIYItCxsXWJtc3nX0\n\n@OpenAI_Support , @Sean-Der could anyone look into this issue?\n\nThank you",
