Thanks @Shah-Fazal - the duplication issue seems resolved.

However, now we’re hitting the other issue I reported here - [AssemblyAI STT high E2E latency even though STT latency is low](https://community.retellai.com/t/assemblyai-stt-high-e2e-latency-even-though-stt-latency-is-low/3416) . We’re getting exteremely high E2E latency even though the individual components are quick e.g. 2026-07-29 07:16:03.412 call\_b0682c40c1cbec7b294faa25b73 info: Latency for response\_id: 1 - e2e: 4907 asr: 285 llm: 1435 tts: 156

Going to report in the other thread as well. I appreciate you continued help!
