# Simple Voice Recorder for TOELF Speaking Test
# Usage:
#  python record.py [output.wav]
# Requirement:
#  Python 2, arecord (often pre-installed on linux)
# What does this program do?
#  First, this program will wait 15 seconds, which is the same length given in the TEFL test for preparing your answer.
#  Second, arecord will begin to record your voice for 45 seconds in which you need to answer the question.
#  After that, the recorded voice will be saved as a wav file.
#  Optionally, you can listen to the recorded voice after your answer.
