A Python script to break audio into chunks of smaller audios and using Google API to get Speech to Text.
View speech2text.py
'''
A hack based on this http://mikepultz.com/2011/03/accessing-google-speech-api-chrome-11/. While with smaller voice samples google speech to text works really good, as length increases quality decreases. So here using audiolab and numPy we are breaking audio sample, in smaller chunks, and removing blank/empty spaces from audio signal and then pushing them to google for processing.
It takes wav file format as input but can be changed to other formats too.
