You're asking whether you can detect an OpenAI Realtime session reconnection and know if you must retry a reply interrupted by that reconnection — yes. Here's how you can handle it. What to listen for • Listen for the session lifecycle events:

reconnecting

(attempting restore) and

reconnected

(restored). These tell you when network recovery happens. • Capture the return from

generate_reply()

(a

SpeechHandle

) so you can track whether the reply completed or was interrupted. What usually happens (so you often don't need manual retries) • The agent synchronizes conversation state on reconnect and resumes where possible. • Interrupted speech is rolled back to the interruption point and playback/resumption is handled automatically if you use the built-in speech handle/resume features. • The

agent_false_interruption

behavior helps avoid treating network glitches as real user interruptions. When to retry manually • If your

SpeechHandle

raised an exception related to the connection or if your app-level logic detects the reply never completed (e.g., no final transcript, no end event), retry generating the reply. • Example flow: a. Call

handle = session.generate_reply(...)

. b. Await or monitor

handle

for completion. c. On error/exception that mentions reconnection or on missing completion events after

reconnected

, call

session.generate_reply(...)

again. Practical tips • Always store and check the

SpeechHandle

state to know if a reply finished. • Subscribe to `reconnecting`/`reconnected` events to pause UI/UX and decide whether to retry. • Tune false-interruption settings (

false_interruption_timeout

,

resume_false_interruption

) so transient reconnects aren’t treated as user interruptions. If you want, tell me which SDK/language you’re using and I’ll provide a short code example showing event handlers plus

generate_reply()

retry logic. Sources: Connecting to LiveKit | LiveKit docs | OpenAI and LiveKit partner to turn Advanced Voice into an API | Turn detection and interruptions | LiveKit Docs
