Phonemes can have hyphens in them, causing misalignment with syllables_data_extractor and timitsounds_converter

[emilyps14]

For example, the sentence: mjmm0_si625.phn "A tiny handful never did make the concert", has a "ax-h" phoneme in the last "the" (see https://catalog.ldc.upenn.edu/docs/LDC93S1/PHONCODE.TXT)

At the syllable level , syllables_data_extractor concatenates phonemes using '-'.join() and timitsounds_converter splits them apart with <string>.split('-'). But this causes the "ax-h" phoneme to be split in two, messing up the alignment between the syllables and the phonemes.
