I listened again to this YouTube posting of the 911 call:

I believe Patsy is commenting to someone off-phone as the call is picked up by 911. At the :10 spot, Patsy's voice - maybe saying the word "hon", then the operator answers as she is saying "hon(?),we need 'em" to someone nearby, and as the operator is acknowledging the call, she quickly states, "police" and the address in order to initiate dispatching of the police to her home as quickly as possible.
She also says "we" and "our daughter" during the call. I think John is the one she is talking to as the call is answered, and her tone indicates to me that she is overriding what he may be indicating to her from the note in the background about not calling police. I have to say I feel her panic sounds genuine, and if she's acting, she's doing one of the finest jobs I've ever heard.
Between :33 and :56 it sounds to me that after the operator asks if the note says who took her, Patsy may have moved near the note and scanned over it and responded to the operator what she was reading herself in the note. The kitchen phone had a tremendously long cord on it which would have allowed her to move nearly anywhere in the area of the kitchen, so even if John did place it on the floor, she could have easily been reading over his shoulder
Listen carefully to 1:19 thru 1:25. Were those the "voices" that were enhanced later? If so, it sounds to me like those several words was repeated 4 times, and sounded the same, like it would have been a repeated elecronic capture of something, possibly not even words. I do admit, though, that the repeated sounds does sound like a sentence, "What did you see".
Was that where Pasty says Help me Jesus several times? Some think they hear"help me Jesus, help me Jesus, their going to arrest" me also.
