Introduction Voice Controlled Robot (VCR) is a mobile
robot whose motions can be controlled by the user by giving specific voice commands. The speech recognition software running on a PC . Software is capable of identifying the 5 voice commands ‘Run’, ‘Stop’, ‘Left’, ’Right’ and ‘Back’ issued by a particular user. After processing the speech, the necessary motion instructions are given to the mobile platform via a RF link.
Speech Input through Microphon e
Computer Sapi and Visual Basic software
User interface with PC is provided by means
of Microphone. When user gives some command for Robot navigation via microphone, sapi software which works as add-on with Visual Basic program, decodes and recognizes the speech and decoded data is transferred to Visual Basic program.
Speech Input through Microphon e
Computer Sapi and
Parallel Port
Visual Basic software
Visual Basic Program compares received
command with Forward, Backward, Left Turn and Right Turn or Stop Command. Visual Basic command then outputs corresponding command on parallel port of PC.
The Parallel port or line printer terminal is
found commonly on the back of a PC as a DType 25 Pin female connector. The port is composed of 4 control lines, 5 status lines and 8 data lines. The original parallel port is a bundle of three ports namely, data port, status port, and control port. Each of the Data, Status, and the Control port have specific addresses assigned to them.
We are using DB25 connector for parallel port. Pins 2 through 9 form the 8-bit data output port. Pins 1, 14, 16, and 17 form the control port which is capable of reading/writing. Pins 10 through 13 and Pin 15 together form the status port.

The system requirement for this application can be broadly categorized under two headings namelyHardware Requirements Software requirements
Processor: Pentium 1/ Pentium II / Pentium III / Pentium IV. Memory : 32 MB Ram (Minimum) Resolution: 800 x 600 pixels. Electronic wireless interface circuit -Opto coupler --433MHz transmitter / receiver module --Relay
Software Requirements: Platform : Any Operating System. Language:
JAVA
Advised Don’t speak to fast but also not to slowly Speak clearly Don’t speak too close to the microphone. 30-
50 cm is a good distance. Try to speak with a good English accent.
Advantages:Can be used for distance control of the robot
with the help of speech only. Controlling machines via typing a command
or clicking with mouse is very common way to do tasks while here we are presenting a new way to control things.
Future scope:Robot voice response feedback can also be
implemented. We can also use this type of robot in military
which is to identified the target or terrorists position by using infrared camera.
Conclusion The voice recognition software has an
accuracy around 75% in correctly identifying a voice command.
But it is highly sensitive to the surrounding
noises. There is a possibility of misinterpreting some noises as one of the voice commands given to the robot.
Also the accuracy of word recognition
reduces in face of the noise. The sound coming from motors has a significant
