Development of the control system of a voice-operated wheelchair with multi-posture characteristics

At present, an electrical wheelchair cannot meet the needs of patients, like paralyzed patients, who spend most of their time on beds. This paper presents the control system of a voice-operated wheelchair, which can transform to a sitting, lying and standing posture. We designed the control system including software and hardware. Voice controlled posture change and driving was realized, the hardware circuit and software program are tested and debugged, the recognition rates of voice control of the wheelchair for the same person are acceptable.
