Android Question Android noUI speech recognition library, punctuation problem

Hi, I am using Biswajit's excellent wrapper for Googles speech recognition without UI. It works like a charm except that it discards spoken punctuation in the result when it is added to a sentence. When spoken as a single word - e.g. "comma" - it is added to the the result, but if it is spoken at the end of a sentence, its discarded.
Google says that the punctuation can be configured, however the wrapper allows no configuration except language, partial result and beeper.
Help is appreciated!
