If you are worried about the 'wh' sound - don't be. Almost all native speakers nowadays would pronounce this word with a normal 'w' sound at the beginning - just like 'wail'.
The breathy 'wh' sound (in when, why, whisky etc) has virtually disappeared from modern English pronunciation, apart from in a few accents, such as some Scottish variants, and in the case of some older people who still hold onto this sound as the 'correct' pronunciation. It's now quite acceptable to say 'whale' and 'wail' in the same way.
