Tara Reid was clearly slurring her words and seemed barely coherent when a concerned bystander called 911 after she claims she was drugged in a Chicago-area hotel … and, we’ve got the audio for you to listen to.

The call — placed by someone who seems to work at the hospital because she refers to Tara as a “guest” — says Reid is “really inebriated” … and adding she can’t even hold herself up in a wheelchair.

The caller calls Tara “Ms. Reid” multiple times … saying it louder and louder, seemingly in an attempt to get her attention — and Tara responds with a series of groans and other mumbled noises instead of annunciated words.
