Character recognition only

[GlobeTracker]

Hi, is there a way to configure the library to capture characters only? For example, when pronouncing the letter 'c', I don't want the word 'see' to be returned; only the letter 'c'. Also, I noticed that when pronouncing 7 digit numbers, a hyphen is included in the results (presumably for phone number formatting). I would like to suppress that 'feature'.

Thank you!
