# English to Spanish Voice Translation App
# Version 3

# Python program that takes in microphone audio and then
# prints it back to the user in both English and Spanish.
# And then if user desires, program will recite text in spanish

# V3 allowed for user to either input/output english or spanish,
# also allowed user to specify voice gender and speaking rate
