Allows the user to create and configure a pronouncing object which will accept strings and have a guess at their IPA transcription, based on a pre-generated list of pronunciations.
The user must specify a lookup object containing this list.
=head1 TODO
Write and implement an API for reading several pronunciations and comparing them (possibly once the whole phrase has been put together).
Try to guess stress for compounds based on a list of compounds and/or at least making sure each word has stress. (This might be impossible to do meaningfully)
