PostPosted: Tue Oct 17, 2006 7:33 am   A speaking clock shell script using festival, date, and cron
I present this script which I built to solve a problem. I get involved, and when I get involved I forget about the passage of time. Pop up windows are intrusive, and I forget to look at the clock in the tray. I needed something to get my attention without interruption, and remind me that time is passing. Back when I used M.S. Windows (circa 1998), I had a speaking clock program that ran in memory, and spoke the time each quarter hour, but it used a lot of resources even when it was just waiting to speak. A speaking clock for Linux was what I wanted, but I could not find one. While searching the WEB, I did find the Festival Speech Synthesis System at the University of Edinburgh. Festival is a command line tool which essentially can 'read' text from standard input (or a pipe), and 'say' it through the sound system.

To make a long story short, I decided to make a shell script to get the current system time and pass it to festival. I run my script each quarter hour with cron. The end result is much like the speaking clock I had back in Windows, but better since my clock only runs when it speaks.

You can copy and paste this script into a text editor, then save it as spktime in the location of your choice. If you want to make it available only to a single user, you can put it in that user's ~/bin directory. If you want to make it available system wide, you can save it in /usr/bin (as root). In either case, remember to make it executable with 'chmod +x ' (no quotes).

To 'speak' the system time each quarter hour where spktime is placed in ~/bin, you can add this line to your crontab:

0,15,30,45 * * * * ~/bin/spktime

or if you placed spktime in /usr/bin, use this line:

0,15,30,45 * * * * /usr/bin/spktime

Here is the script:

# 4. provide contact information

# To speak the current time each quarter hour
# save this script as spktime in your ~/bin directory
# and add the following line in your crontab:

# 0,15,30,45 * * * * ~/bin/spktime

# This is the end of required comments.
# now to the real job Smile.

# Set up a variable to hold the current minute
# of the hour using the date command:
MIN=$(date +"%M")

# And another to hold the current Hour:
HR=$(date +"%l")

# A third to hold some introduction text so I know
# I am hearing the current time:
INTRO="The time is, "

# Use a case statement to change the minute
# number to the equivalent word, but make the
# zero minute "o'clock". Handle all sixty minutes
# of the hour so this works correctly for any time.
