ABSTRACT:
A voice command device (VCD) is a device controlled by means of the
human voice. By removing the need to use buttons, dials and switches,
consumers can easily operate appliances with their hands full or while
doing other tasks. Some of the first examples of VCDs can be found
in home appliances with washing machines that allow consumers to
operate washing controls through vocal commands and mobile phones
with voice-activated dialing.
This project Voice Controlled Robotic Vehicle helps to control robot
through voice commands received via android application. The android
mobile is used to capture the voice commands and process those voice
functions. The vehicle responds as per the command received. Different
words are integrated with the different movement of the vehicle. The
whole process is done wirelessly using the android phone’s internal
Bluetooth along with the HC-05 Bluetooth Module on the vehicle end.
WORKING PRINCIPLE:
The Android phone used is installed with the relevant application that
receives the user commands and interprets them accordingly. Every
word is aligned a different code. When the user speaks the predefined
words like left or right, the data is sent to the microcontroller over
Bluetooth.
The HC-05 Bluetooth Module on the vehicle end receives this data and
sends it to the microcontroller. This data is then interpreted in the
microcontroller and the microcontroller further controls the motion of
the motors accordingly. Thus the vehicle moves left, right, forward or
backward as per the data received from the microcontroller.
The LCD Screen is used to graphically show the movements of the vehicle
along with other parameters.

APPLICATIONS:
 Playing back simple information: If you have customers who
need fast access to information. In many circumstances customers
do not actually need or want to speak to a live operator. For
example, if they have little time or they only require basic
information then speech recognition can be used to cut waiting
times and provide customers with the information they want.
 Call steering: Putting callers through to the right department. By
introducing speech recognition, you can allow callers to choose a
‘self-service’ route or alternatively ‘say’ what they want and be
directed to the correct department or individual.
 Removing IVR menus: Replacing complicated and often
frustrating ‘push button’ IVR.
 Automated Identification: Where you need to authenticate
someone’s identity on the phone without using ‘risky’ personal
data.
