No. But I think the pronunciation could be clearer. If you're a native speaker, of course you hear what you expect to hear. I'm too new to the language to have those expectations.
Sometimes I use grammar to make the correct choice when it sounds like it could be two different things - usually only one is grammatically correct. In this case, that doesn't work, since either would be grammatically correct (I believe). Since, to my ear, the recording is indistinct, I have nothing else to guide my choice.
