Description: This is the script I use to manipulate pitch by +/- 0.5 ERB. I've used this method in all of my papers since I switched to ERB from Hz (you can edit the script and set it to Hz if you want). It's set to default male values, with plenty of pitch floor space to make low voices. If you want to manipulate female voices, try a 100-500 Hz pitch range. The script will also normalize amplitude to 70dB using RMS. You'll need a manipulation amount, an input directory full of .wav files, and an output directory. It only does one direction of the manipulation. Make sure you add a slash at the end of any path. Make sure no spaces are in your file names.
