Siri voice recognition problems

I work at a company named Bay Computer Associates and Siri refuses to recognize the word "Bay". It seems to just miss the "B". I don't think this was happening before. It makes me think Apple is playing with the recognition algorithms on the server side. I sent feedback to Apple about it, but of course the whole process is one giant black box. I wish there was some way to influence the training of Siri, like by correcting her interpretation.

I wonder if others have seen cases where certain words or phrases suddenly get dramatic degradation or improvement in recognition.
