fix string typo: zlib to GSM compressor
	modified:   src/phonetic_synthesizer_ta.c

Desc : 	fixed segfaults due to type mismatch.
	in phonetic_synthesizer_ta.c:generate_phonetic_script_ta()
		num is declared as char(supposed to be char*) which makes an implicit cast to
		return value of call to ta_parseMiscellaneous() as char
		hence " " is parsed as '\020', 0 as '\000' and the like.
		This causes segfault in strcat().

Fix :	changed num :: char to char*
