Abstract:
This project proposes a design of voice activated with noise reduction system using
microcontroller. The system is aimed to makethe voice oriented command is more
cleared. A voice recognitionmodule has been added to the wireless system to store
the voice command. The voice command is the system comprisesof transmitting
section and receiving section,the system uses the Radio Frequency (RF)
technology for transmitting and receiving data. Initially, the voice command is
stored in the data baseusing the function keys. Then the input voice commands are
transmitted through wireless. The voice receivedis then processed in the voice
recognition system where the feature of the voice command is extracted and
matchedwith the existing sample in the database. The module recognizes the voice
and sends control messages to themicrocontroller. The programmed
microcontroller is then processes the received data and switches the
respectiveappliances via connected driver circuits. The results gained from the
system were very good. The system was able to filter the noise and recognize the
voice command. Severalsoftware was used for the simulation purpose such as
BASCOM and PROTOUS.
