Remarks

Added in LumenVox version 11.2, LV_SRE_IsValidSampaPhonemeString forms part of a number of changes implemented for improved custom lexicon support.  These changes included the option to use either SAMPA or LumenVox native format (similar to CMU or ARPABet format) when working with custom lexicons.
