Problem Description
Select a card from the displayed playing cards, but do NOT point the
mouse to it. Instead speak the name of the selected card into your
speakers, and this program will remove it from the display.
Accuracy has been proven to be nearly 100%! Download the the
program and try it for yourself.
Background & Techniques
Due to recent advances, it's now possible to sense the vibrations caused by the human voice as the sound impacts the speakers attached to your PC.
The induced currents feed back through the sound card and can be
detected. Any output sounds are then subtracted and the result fed
into a small speech-to-text digital signal processor capable of
recognizing a limited vocabulary.
Or --- it might just be a trick.
The graphical Card component introduced back in
Cards #2 is used to create the
card images.
The panels used for displays overlap each other
on the screen. At design time you can right click and select
"Send to back" to view the hidden panels.
I'm sure you will understand that I really
can't discuss more about the program here without revealing trade
secrets. You'll just have to check it out for
yourself.
Running/Exploring the Program
Suggestions for Further Explorations
Additional error screens could be displayed
advising the user about techniques to improve recognition accuracy,
perhaps two or three like the following: ("Speak
louder", "Speak slower", "Speak in a
higher pitch please", "Try tilting your head to the
left", "Nasal voices are easier to recognize, try
holding your nose", etc.)
