if i understand you say to test the library first, right? I' ve already written a simple c++ class for use the library, a TTS.h, TTS.cpp and a main.c file in which i create a TTS object and call the 'speak' method, i got no problem, it work fine. I've written a little Makefile to simplify the compilation

#Makefile for TTS
VERSION = 0.1

CC       = g++
ISEARCHDIR = -I/usr/include/speech-tools/ -I /usr/include/
LSEARCHDIR = -L. -L/usr/lib/
OPTIMIZE = -O3 -s -fomit-frame-pointer
CFLAGS   = $(DEFINES) $(OPTIMIZE)
LFLAGS   = -lFestival -lestools -lestbase -leststring -lncurses

PROGS    = FestivalExposure

PROGS_O  = TTS.o

OBJ_SO  = TTS.so

all : objs progs

progs : 
        $(CC) main.c $(PROGS_O) $(LSEARCHDIR) $(LFLAGS) -o $(PROGS)

objs :
        $(CC) TTS.cpp $(ISEARCHDIR) -c
        
sobjs :
        $(CC) TTS.cpp $(ISEARCHDIR) $(LSEARCHDIR) $(LFLAGS) --shared -
+o $(OBJ_SO)

provaOBJ :
        $(CC) TTS.cpp $(ISEARCHDIR) $(LSEARCHDIR) $(LFLAGS) -o $(PROGS
+_O)

clean : cleanbin
        rm -f *.o *~

cleanbin :
        rm -f $(PROGS)

Tonight i'll try xs with the TTS class, writing the typemap, etc... P.S.: sorry the my english
