# LIST OF PACKAGES NEEDED:
# you need to install the following packages:
# sudo apt-get install python poppler-utils festival festvox-rablpc16k lame espeak wavbreaker
# HOW TO USE:
# 1.create a file with the name pdf2mp3 and copy the content of
# the whole text in there
# 2.make the file an executable via:
# >>> chmod +x pdf2mp3
# 3.copy file to /usr/bin to make usage of program possible from everywhere on your computer:
# >>> sudo cp pdf2mp3 /usr/bin/
# 4.after that get help calling:
# pdf2mp3 -h
#
# 5.EXAMPLE:
# you want to convert yourfilename.pdf into a mp3 file, then just type:
# pdf2mp3 -v en -f yourfilename.pdf -o yourfilename.mp3 (for the english voice 'en',
# for german voice 'de', type:
# espeak --voices to get list
# of voices available on your system)
