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).
