A cooking appliance is designed to enhance voice recognition performance by integrating a digital controller door with advanced features. The appliance comprises a main portion for cooking, a display door with user interface capabilities, and several door-mounted components including a microphone and a controller. This setup allows the appliance to adjust its operations based on voice commands, improving user interaction and efficiency.
The appliance's core includes a cavity for food and functional components necessary for cooking. The display door acts as an interactive hub, providing visual feedback and control options. The microphone plays a crucial role in voice command recognition, and the controller manages the transition into a command word recognition mode upon hearing a wake-up word. This mode temporarily adjusts the operation levels of certain components to reduce noise and enhance voice recognition accuracy.
The system is designed to mitigate interference from noise generated by the appliance itself or surrounding devices. By controlling the operation of noise-generating components, the appliance can maintain clear voice recognition. This is particularly useful when the appliance is positioned above a heating device, where additional noise and heat could otherwise impede performance.
The appliance employs a sophisticated method to enhance voice recognition by modulating the noise levels during the command word recognition mode. This involves either stopping noise generation or significantly reducing it based on the voice recognition pattern. Such adjustments ensure that the appliance accurately interprets user commands, thereby improving the overall user experience.
The appliance's design emphasizes seamless cooperation between the door's hardware and software with the main control components. This integration supports a contextual control scheme, allowing for precise voice recognition even in challenging environments. The approach not only enhances functionality but also sets a new standard for interactive cooking appliances, highlighting the potential of integrated digital control systems in everyday home appliances.
