Home appliances control using speech recognition
The comparison graph function. Beneath the movable part of bed there is a box type structure on the top of which motorized jack is fixed which will lift the bed moveable part up or down and in the box structure the home automation system electronics is placed as shown in Fig. Add Tip. Many of the projects made with a Raspberry Pi are open and well-documented as well and are things you can build and modify yourself. The illumination bed sensor automatically turns off the lights when sun light is 9 Up Set the bed elevation to enough to see things around also a time delay is added that if degree with respect user forgot to turn off lights or any device the will be to the stationary part of automatically turned off to conserve energy. Voice Command Function performed 21 ControlOn 1 1 Load 1 the 0 control 1 and off 4 Under the noisy condition out of five trials only three were command to recognizer. When a relay contact is Normally Closed NC , there is a closed contact when the relay is not energized. The RF by the microcontroller and corresponding control action is transreceiver is used to send these commands to the controller taken. Bed Modelling and Elevation Control Mechanism The bed for home automation project is used along with a motorized jack.
The person can sleep comfortably in this position. Thus only 7 the previously stored trained voice samples.
Voice control system
The home automation system  proposed two ways to Index Terms— Home Automation System, Physically control home appliances that are by using timer or by using Challenged People, Voice Recognition Module V3, Arduino the voice commands. The ideal conditions. The sleeping position is the position where bed is at degree elevation to the ground as shown in Fig. Microphone and Voice Recognition Module The microphone used to get voice commands to the voice recognition module is a simple collar type microphone with 3. The 5V supply requirement can be fulfilled from Arduino board itself but for the 12V 5Asupply we need additional supply circuit. In addition, relays are also widely used to switch starting coils, heating elements, pilot lights and audible alarms. Jawarkar, Vasif Ahmed and R. The appliances by two methods by voice commands or by using experimental results validate the functions of the proposed system. It is cheaper and uses less power than the B.
It consists of training of voice recognition module. The controller used for the proposed system as shown in Fig.
Relays control one electrical circuit by opening and closing contacts in another circuit. Shimi S.
The adjustable bed offers three elevation positions sleep position, rest position and sitting position. If the patient needs any help then by voice the embedded circuit of power supply on PCB.
The motorized jack is used to lift up the bed Fig.
Beneath the movable part of bed there is a box type structure on the top of which motorized jack is fixed which will lift the bed moveable part up or down and in the box structure the home automation system electronics is placed as shown in Fig. The Arduino microcontroller is based on the ATmega It consists of training of voice recognition module. Zigbee wireless first before it can be used to recognize commands. However, the Raspberry pi used in the project is model 2 B. General Output Pins on the board could generate several The data from the illumination sensor is processed in Arduino kinds of waves while corresponding voice command was controller and based on a set point value the automatic control recognized. Buzzer Arduino. Upon successful recognition of voice command 2 shows the list of commands and the functions performed by the control action corresponding to that command is taken. Thus only 7 the previously stored trained voice samples. Buzzer allows disabled person to notify the to the stationary part of guardians whenever the person need help. Light Sensor tap transformer of V is used here. The jack uses the motor for lifting up the bed and bringing back to ground position and the motor direction is controlled by the relays. O of relays is used in command he or she may turn on the buzzer for help.
