heteronym problem

[sciai-ai]

Hi

I have an example heteronym 'wind'

a) The 'wind' is blowing

b) Lets all 'wind' down.

For both these cases, the g2p 'wind' is pronounced the same

Is there any problem with the POS tagging, how can we get the correct pronunciation [W IY1 N D] and [W AY1 N D]

[sciai-ai]

Do we need to train the g2p again?
