Abstract：Objective To design a new and more humanized physiotherapy equipment. Methods The pulse width modulation (PWM)
frequency, duty cycle and intensity were dynamically adjusted at any time according to the patient’s voice by using intelligent voice
single chip microcomputer control technology, so as to achieve human-machine dialogue, fully understand the patient’s will and
stimulate the lesions. Results Through the single chip microcomputer calculation, the ASR arithmetic of LD3320 could recognize
the voice of different people without difference. It had strong anti-noise ability and good practicability. Conclusion Based on the
single chip intelligent voice technology of physiotherapy equipment, the treatment can be prolonged or targeted according to the
patient's will, safe and reliable, stable performance, can better play the role of physiotherapy equipment rehabilitation.The design is
safe, reliable, stable, and can better play the role of rehabilitation physiotherapy.
