Its not that odd. If you think about it, when you say the phrase “i can really do that” you pronounce the ‘can’ in a very short ‘cn’ way (regardless of your accent, I think), and its different with “can of beans”. So I wouldn’t really call it a bug – there is no way to differentiate the two unless you go into the complexity of analysing the context. Anyway, your suggestion of “CAH ANN’ works a treat! And in my app, i am more likely to come across the ‘tin’ can that the other one, so i am happy to go with that pronunciation. Thanks.
