>How can one explain that?

She didn't actually do it, or at least she didn't do it to the degree that you think she did. Instead, you had an intense enough experience that your memories of the tone, cadence, and choice of words of your voice, were altered after the fact.

(Human) memory is extremely unreliable.

It’s not memory, it happened at the time, within around 30 seconds, between me hearing the voice and her imitating it.

Good way to disqualify the opinion or experience of anyone.

People can mix up exact details and whether two things feel the same in that amount of time, especially if they recently took drugs.

Look, you specifically asked for a skeptical explanation. You're right that it's not a disproof, but it does mean your experience isn't particularly convincing as an anecdote.

Parent poster is being unnecessarily smug and dismissive, but the point is that however close in time the events were, they are now entrenched in fallible memory.

I mean people have deja vu which is literally your brain misinterpreting a currently-happening experience as a memory. Medical literature is filled with tons of quirks of human perception and memory, and we frequently find new ones and new twists on existing ones.

It is not remotely a stretch to attribute "I recognized this woman's voice as someone else's voice" as just a run-of-the-mill fault of perception and memory. Especially when the alternative at hand is apparently something supernatural (or, at least, new physics).
