The way the voice-based control system works when using voice recognition was that the user records their voice to be stored in the database as a sample to be used in verifying the voice input later. Input in the form of voice commands given through the microphone, was forwarded to Easy VR as voice recognition which will match the voice sensor output data that had been sampled. The microcontroller was Arduino which will process the output from EasyVR and activate the controlled device as in “Fig. 2”. If the voice command used was in the form of speech recognition, the system works by utilizing speech to text on the Web Speech API, the input was then converted into text. Users must connect to the internet for intermediary data exchange in order to access the Speech API Web server. The input that was processed will be responded by the server by sending a switch on or switch off command. The microcontroller would then run the relay according to the command received.
Figure 2 Block diagram of how the system works Remote control can be done using bluetooth and
NodeMCU. Controlling using bluetooth, the system was run by opening an application that has been made on Android. Then given the command to activate the controlled device. This command would then be converted and sent via bluetooth to android using a voice and speech detector. The next command was processed by the Arduino Uno microcontroller and will be executed to turn on or turn off electronic devices and send feedback to Android as in “Fig.3”. In controlling using NodeMCU, the system worked by giving voice commands as input through an application that has been designed on Android which would then be converted and processed in Arduino and the data was sent to the NodeMCU module.
