| Limb rehabilitation equipment can provide stroke patients with safe and efficient recovery of motor function,but due to the inconvenience of limb movement,it is difficult for patients to operate limb rehabilitation equipment by themselves.Voice interactive control is an important way of human-computer interaction.The application of voice interactive control technology in limb rehabilitation equipment can assist patients to control the equipment independently,so as to improve the convenience of patients,reduce the boredom of patients,and improve the effect of rehabilitation treatment.Different from the general household equipment,when voice interactive control is applied in the field of intelligent medical,such as limb rehabilitation equipment,the security of voice control becomes a problem that must be solved.In this paper,a reliable and efficient voice interactive control method for limb rehabilitation equipment is studied(1)Research on voice control command construction method of limb rehabilitation equipment.This paper studies the Shannon informatics characteristics of Chinese,studies the similarities and differences of Chinese pronunciation,analyzes the causes of common errors in speech recognition according to these research conclusions,studies the experimental screening method of speech command for limb rehabilitation equipment,and selects some speech commands.(2)Research on voice control safety verification method of limb rehabilitation equipment.This paper studies the security verification method of voice interactive control,studies and designs the voice verification code for voice command of limb rehabilitation equipment,and tests the security check and error correction effect of the voice verification code through experiments.(3)Research on speech control noise reduction method of limb rehabilitation equipment.This paper analyzes the noise interference environment when using speech control function of limb rehabilitation equipment,studies different interference modes of irrelevant speech noise in this environment,and studies a speech separation method based on irrelevant speech noise interference mode and speech signal TDOA positioning information.The actual effect of this speech separation method is tested through experiments.(4)Research on structured information extraction method of voice control command for limb rehabilitation equipment.This paper studies the improvement of the pre training model of speech command structured information extraction for limb rehabilitation equipment,studies the transfer learning method of the pre training model,and tests the actual effect of the model on patients’ speech command information extraction through experiments. |
