[hts-users:04519] too few observation sequences

Hi hts-users,

We are training a new voice and running into this error:

 ERROR [+2121]  HInit: Too Few Observation Sequences [0]
 FATAL ERROR - Terminating program /proj/tts/hts-2.3/htk/HTKTools/HInit

We understand that this error may happen because of too few examples of the phoneme, or because they don't each contain enough frames, but we have more than 3 examples of this phoneme in our data (the minimum specified in the HTK book) and they all contain more than 5 frames (which sounds like the minimum required according to other posts on this list) -- is there any other reason why this error may occur?
