Abstract: Objective To study the human performance and control characteristics of speech interaction in the teleoperation tasks of robotic manipulator.Methods Based on the simulation platform for teleoperation ergonomic research and the iFLYTEK SDK of speech recognition and synthesis,a simulation test platform was developed for teleoperation of robotic manipulator in touch or speech interactive mode.According to the tasks of the robotic manipulator,the speech recognition rate was tested and the performances of three typical teleoperation tasks were compared for the two interactive methods.Results Compared with touch interaction,speech interaction could significantly increase operation speed,decrease operation difficulty,reduce visual load,operation load and recognition load under the same operation accuracy for the semi autonomous control tasks of robotic manipulator.Conclusion Speech interaction has better adaptability than touch interaction for complicated semi autonomous control tasks.It could optimize control performance,experience and work load.
