speak.sh, make your computer speak to you

Want to learn english, but no one wants to speak with you in english? Ever imagine to speak with computer? This script can make your computer speak to you. Note that the script stolen from here. And you will need festival.

#speak with your computer
#dependency: festival

x=`wc -l $1 |awk '{print $1}'`
y=`expr $x - 1`

while [ $i -le $y ]
        echo  ">>>`head -$i  $1 | tail -1` \n"
        head -$i $1 | tail -1 | festival --tts
        j=`expr $i + 1`
        echo  "`head -$j $1 | tail -1`"
        i=`expr $i + 2`
        read pencet
exit 0

and a sample dialog file, save as test.txt:

Hi, whats your name
My name is ...
how are you?
I'm fine, thanks

Give the permission 755 to speak.sh, and run it:

$ speak.sh test.txt

Please send me improvement for the code, and the dialog file too, so I can build a debian package. Or someone can do it for me?
