Voice change mid-scene

So I just made it to the Fortress of Meropide and during the tour by Wriothesly, I swear Paimon’s voice changes between three lines.

The “Hard to handle” line had her original voice

Then the “Welfare Meal” line I swear her voice changed.

Then the “This place doesn’t seem so bad after all” line goes back to her original voice.

Am I going crazy?
