As You Wish 2.1 - Asim Abbasi
In The Press
This project got the eyes of the news media. For further details click on the following image.
Basics
This project is one of the application of Voice Recognition. Voice
Recognition has its origin from DSP (Digital Signal Processing), the
term with which most modern Electronic and Electrical Engineers are
familiar.
Digital Signal Processing is one of the most powerful technologies that
will shape science and engineering in the twenty-first century.
Revolutionary changes have already been made in a broad range of fields:
communications, medical imaging, radar & sonar, high fidelity music
reproduction, and oil prospecting, to name just a few. Each of these
areas has developed a deep DSP technology, with its own algorithms,
mathematics, and specialized techniques.
Digital Signal Processing is distinguished from other areas in computer
science by the unique type of data it uses: signals. In most cases,
these signals originate as sensory data from the real world: seismic
vibrations, visual images, sound waves, etc. DSP is the mathematics, the
algorithms, and the techniques used to manipulate these signals after
they have been converted into a digital form. This includes a wide
variety of goals, such as: enhancement of visual images, recognition and
generation of speech, compression of data for storage and transmission,
etc. Speech generation and recognition are used to communicate between
humans and machines. Rather than using your hands and eyes, you use your
mouth and ears. This is very convenient when your hands and eyes should
be doing something else, such as: driving a car, performing surgery, or
firing your weapons at the enemy.
Speech recognition is a classic example of things that the human brain
does well, but digital computers do poorly. Digital Signal Processing
generally approaches the problem of voice recognition in two steps:
feature extraction followed by feature matching. Each word in the
incoming audio signal is isolated and then analyzed to identify the type
of excitation and resonate frequencies. These parameters are then
compared with previous examples of spoken words to identify the closest
match. Often, these systems are limited to only a few hundred words; can
only accept speech with distinct pauses between words; and must be
retrained for each individual speaker.
Purpose
The purpose of creating this project is to control all home equipments
e.g. Fans, Lights, Door motor, Electric Heater, TV, VCR, Water Pump etc
through Voice. The user will no longer have to move from his seat, just
to turn on the Fan. He will just call the Fan with its Name, rest will
be done by "As You Wish".
Project Details
This project has two parts one is related to Software and other related
to Hardware. Normally you have to plug the hardware to your system after
that you have to install the software. First of all, connect the
Microphone to the sound card and check whether it is working or not by
using the Sound Recorder Utility in Windows.
You have to plug the Hardware to the any Parallel Port of you PC. There
are 24 sockets available on the Hardware, in which the devices to be
controlled will be plugged in. There is also a AC supply Plug which you
have to plug in the 220v~ supply. Now the Hardware setup is completed.
After the completion of hardware setup, start your computer and run the
As You Wish software (its is assumed that the software has been
previously installed). Now you can create the menu of devices names. The
Device Numbers on the software and Hardware are the same. Click Save
when all the names have been entered.
Click Config button to set the configuration of the software. Write the
address of Parallel Port on which you have connected the hardware. You
can also train the Voice Engine with your voice by clicking Train. Click
Ok. Click Activate. Wait for the Listening status to appear. Now its
ready to obey your previously entered commands.
