Hey netizens! This is the first Instructable I've made! This site has helped me immensely as a student, learning to DIY. I want to help this site in return.
Now, for the details, this is a simple talking clock that says the day, date, month, time and year in English using the picoTTS. A TTS is a text to speech converter and is a nifty little tool that can go well with a wide range of projects. There are more TTS softwares like eSpeak and Festival but I found pico to be the best.

Step 1: Things Needed
An Audio Output
A working internet connection to the Raspberry Pi.
Step 2: Let's Get Started!
I've referred to this site while installing
I've tried to break it down
1 - Go to the Command Line and type - nano /etc/apt/sources.list
2 - Check if it contains (uncommented) the following lines:
deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb-src http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
To uncomment, delete the # that may be in the beginning of any line.
Depending on your version of Raspbian, the wheezy will be replaced by your respective version name. For me it was jessie.
Step 3: Lets Get Installing!
Type these commands in command line
sudo apt-get update
sudo apt-get install fakeroot debhelper automake autoconf libtool help2man libpopt-dev hardening-wrapper
apt-get source libttspico-utils
After downloading the sources, you should find a folder named like svox-1.0+git20110131 that will contain all the files. Note that the last part could be different, so please check before proceeding.Enter the sources folder and prepare the packages:
dpkg-buildpackage -rfakeroot -us -uc
Step 4: Final Steps
Now, in case you are on jessie, the last command will stop pretty quickly.
In that case, download these files
Install as so-
sudo dpkg -i filename.deb
For example sudo dpkg -i libttspico-utils_1.0+git20130326-3_armhf.deb
Install the packages in order of downloading, ie. /libttspico-data, libttspico0, libttspico-utils
If you are on wheezy, the above step isnt necessary. Install in the same way!
Step 5: Getting It to Work
pico2wave -w test.wav "it works! "
If this code works, your project is 90% over.
Step 6: Making a Clock
If you type date, into the command line it will give you the date. I used this function to create an executable shell script.
Type nano talking_clock.sh, paste the following code and press Ctrl+o, Ctrl+x.
while : do
pico2wave -w test.wav "Today is $(date +%A) $(date +%d) $(date +%B) $(date +%Y). The time is $(date +%l) $(date +%M) $(date +%p) $(date +%Z)"
chmod +x talking_clock.sh
To execute -
#!/bin/bash - specifies the language we are using, in this case its bash
while : do - an infinite loop
pico2wave -w test.wav "Today is $(date +%A) $(date +%d) $(date +%B) $(date +%Y). The time is $(date +%l) $(date +%M) $(date +%p) $(date +%Z)" - creates a .wav file named test, that stores the converted string in the following format... "Today is Thursday 01 January 2016. The time is 01 59 PM IST"
To learn about some more functions, type date --help in the terminal window.
Step 7: Thank You!
You could check my instagram (@arpimatic_lab), where I've uploaded a video of this at work!
I'll try to elaborate on the concepts at work soon.
Thank you all so very much!
I'm open to constructive criticism.
