This research aims to design and develop a humanoid robot controlled by voice commands using the CMU Sphinx speech recognition system, evaluate its performance by experts, and study user satisfaction. The ADDIE Model was used to analyze user needs and problems, design the system for developing the robot, develop the robot's structure and control program, and develop a voice command application using Java in Android Studio. The system was tested with target groups and its performance was evaluated to improve and enhance its functionality. The humanoid robot comprises hardware including Arduino Nano, Expansion Board, servos, and Bluetooth HC-05 module. The target groups for the research included 3 experts from Sisaket Rajabhat University and 30 high school students. The research tools included a satisfaction questionnaire with a 5-level rating scale. The statistics used for data analysis were mean and standard deviation. The results showed that users had a high level of satisfaction in all evaluated aspects, with an overall mean of 4.42. The highest score was for ease of use at 4.70, followed by response speed at 4.43, and interaction capability at 4.35. The lowest score was for the accuracy of speech recognition at 4.20. The expert evaluation indicated that the robot performed well in accurately and quickly responding to commands, but improvements in speech recognition accuracy are needed to further enhance user satisfaction and system performance. This research demonstrates the potential of using humanoid robots to enhance learning experiences and effective interaction among youth.
