I just made a shell script to make my computer read the current time. I got the idea from this blog post. This script requires festival to be installed (read the blog post). This script could be useful for common reminders (like class).

# Converts a string of two digits to words according to a use number
# Arguments: (digit string, use number)
# If the use number is 0 then the number is treated normally
# If the use number is 1 then the number is treated as an hour
# If the use number is 2 then the number is treat as a minute
convert_pair()
