そのあともChatGPTを問い詰めて、結局、以下のようなクレーム報告のメールをOpen AIに送ったところだ。 Subject: Unexpected ChatGPT voice activity while my phone was locked
Hello,
I would like to report what appears to be an unexpected voice activity or possible bug in the ChatGPT Android app.
I was using a Sony Xperia 1 VI (Android). On August 9, 2026, while I was walking outside, my phone suddenly started playing a loud voice even though:
I had not opened or launched the ChatGPT app.
I was not using ChatGPT at the time. I had not been having a conversation about the topic being played.
At first, I assumed that a YouTube advertisement or another app had started playing audio accidentally.
However, I later investigated and found the following:
Android's Privacy Dashboard shows that ChatGPT accessed the microphone starting at approximately 13:01 and that the access lasted for 39 minutes. There is a ChatGPT conversation recorded at approximately 13:19 that contains an audio recording/playback component. When I played the recorded audio, it initially contained a female voice explaining the difference between "bring" and "bring in." This was a topic I had actually discussed with ChatGPT the previous evening. However, partway through the same audio, the content suddenly changed to a conversation about having lunch and finding a café near Chitose-Karasuyama Station. I had not had any such conversation with ChatGPT that day. I had not been planning to go to Chitose-Karasuyama, nor had I been looking for a lunch restaurant there. Chitose-Karasuyama happens to be the area where my parents' home is located, but I had no plans to visit the area that day. The conversation about Chitose-Karasuyama does not appear as a normal conversation in my ChatGPT history. The only relevant record I can find is the audio/transcript associated with this incident.
The combination of these facts makes me concerned that a ChatGPT voice session may have started or resumed unexpectedly while my phone was locked, or that audio/content from different conversations may have been incorrectly combined.
I have preserved the relevant conversation and have not deleted the audio recording. I can also provide screenshots showing the Android microphone access history and the ChatGPT settings.
Could you please investigate whether there was any unexpected voice session, background activity, or other technical issue associated with my account or device around 13:01–13:40 on August 9, 2026?
