[Doctor Who] When Clara was inside the Dalek armor, she couldn't say worlds like "love", but in a 9th doctor episode, a dalek holding Rose hostage says the word "love". How did it manage that?

Also, why didn't Clara just say "Run you clever boy"? The doctor would have known that it was her immediately.

Edit: The title is supposed to say "Words, not "Worlds". Typo error, sorry.

Daleks existed in a number of incarnations throughout time.  While they are drakonian bout their genetics, they are not about their technology.  As such, the quality of their armor varies widely.   Not just in simple ways, but in more complex ways like their programming.  The one Clara was in was quite advanced, with commensurately strict programming.
