Bash script to create wave files using google text to speech online service.

./text2mp3.sh /tmp Please convert this text to a wave file for me!
f056e7eb018997c427083320c50a168a.wav

The script receives two parameters, the directory to be used and the text to be translated.

guilespi$ ./text2mp3.sh 
Usage: ./text2mp3.sh [directory] [text]

There are three important parameters to configure the script

LONGEST_TEXT=100 
LANGUAGE="es" 
GOOGLE_URL="http://translate.google.com/translate_tts?tl=$LANGUAGE&q=" 

LONGEST_TEXT is the maximum number of chars the google service will take before failing with a 404 error. LANGUAGE is the language of your choice GOOGLE_URL is the url used to generate the wave file.

Usually you'll only change the desired language.
