In general, a wheelchair that is often used is a standard wheelchair that is used in hospitals with operations using human labor or assisted by others. However, the use of a standard wheelchair is considered quite difficult because it requires enough energy to be able to move the wheelchair if no one else is helping. Along with the times, motorized wheelchairs have been built and operated using joysticks. The addition of a motor to the wheel helps the user so that the user does not need to use power anymore in moving the wheelchair. In this paper, we develops the ability of a wheelchair that can move using voice instructions. We use the Hidden Markov Model (HMM) method which is utilized in the Pocketsphinx library. This library supports the speech recognition feature to recognize spoken words that implemented at Raspberry Pi mini-computer with the Raspbian operating system. Based on the test results, the average success the word of “maju” 97%, the word of “mundur” 88.5%, the word of “kanan” 94%, the word of “kiri” 92%, the word of “stop” 98.5%, the word of “tamu” 97.5%, the word of “tidur” 91.5%, the wo
