Why Our Project ROCKS!

• Instead of pushing a button to end a turn in
  chess, a user can now say a pre-recorded word to
  end their turn.
• Useful for those who may have lost a limb but
  still desire to play speed chess.
• (They have voice activated chess boards)

How The Clock Works

• Players record end turn sounds
• Players record time setting sounds
• Game of chess begins
• When finished with a turn say the end turn sound.
• A players remaining time will elapse until they
  finish their turn.
• A player wins when they checkmate their opponent
  or their opponent runs out of time.

The Voice Direct 364 chip

• 3-modes for word recognition
• Speaker Dependent
• Single word continuous listening
• Multi-word continuous listening
• We use multi-word continuous listening with the
  following words
• Yo
• Time Clear, Up, Down, Up 5, Down 5
• Mama

LCD Output

• 8-7 segment LCDs
• 4 BCD to 7-segment decoders
• Input from microcontroller
• Lots of wires.

Putting It All Together
11
Challenges

• Needed 35 output, 10 input pins only have 40
  pins.
• Wire both displays to the same input pins.
• Alternate which players remaining time is sent.
• Voice recognition.
• Recording includes background noise
• Words must not only be the same, but be said the
  same.
• Record and use in the same environment.
• SilencePlease!

More Challenges

• End game speaker.
• Toggled an output pin to create a tone on a
  speaker.
• Created a circuit so the speaker was loud enough
  without drawing too much current.
• Pins broke in the voice chip connectors
• Bought a second voice chip.

13
The Final Challenge

• Getting it in the Phone book
• Cutting out the phone book
• Supplying Power
• Making everything fit (without disturbing the
  delicate wiring)
• The requirement Patience

Conclusions

• Integrated voice chip, microcontroller, and
  output devices.
• Learned about circuit construction and
  microcontroller programming.
• Built a voice activated chess clock that works
  more or less!

Problems To Work On

• Main Problem
• Voice recognition not perfect
• Better chip
• Minor Problems
• Better end game sound. (A victory cheer or taunt)
