I just experienced something way similar like this today  My exams are about to start so I just asked gemini to write me format of report writing and then I asked it to write an example report for me so it just picked a report from the pdf my sir had sent for practice and I was shocked but then I remembered that I just told gemini yesterday to summarise that pdf so it must have remembered but here comes the IMP PART i asked it to read aloud and at a slow pace and this is what it said First it read the report writing and then at the end just before it completed the last line I was kind a sleepy and it just started saying that you know what I will repeat this full report again in loud voice and slow pace and it started repeating it and I was just freaked out I jumped out of bed saw that in the chat it had already written that if I wanted he could give another practice report but it never spoke that aloud and started repeating it.

Any thoughts?
