The ESP32 microcontroller is used in this project to develop voice applications for device automation. The ESP32's built-in Bluetooth and Wi-Fi capabilities make it the perfect platform for Internet of Things (IoT) applications, where it can perform voice-activated tasks both online and offline. An external microphone records the voice commands, which the system stores before being interpreted by edge-based speech recognition software like TensorFlow Lite and Vosk, or cloud-based services like Google Assistant or Amazon Alexa. Relays or the ESP32's GPIO pins are used to translate the voice commands into control signals that can be used to operate lights, fans, and other devices. The system can function in any network condition thanks to its support for both offline and cloud computing. The application showcases the versatility of the ESP32 in real-time voice-activated home systems, which improve accessibility and user convenience through voice control.
