Abstract: In view of the complex working environment, inconvenient operation and low efficiency of agricultural intelligent equipment, the application prospects of voice technology in agricultural intelligence were prospected. The overall architecture of the software and hardware of the voice system in agricultural equipment was proposed, and the voice technology was divided into four parts with voice prompt, voice alarm, voice control and visual voice.In the ROS development environment, the python compilation language was used to establish the control software system framework, and the complete set of control software was divided into crop information detection unit, operation information detection unit, voice signal receiving unit, operation command control unit and voice broadcast-alarm unit.Each modular programming of functional units was conducted to realize multi-functional synchronous and coordinated operation of the entire system.Taking the grape picking robot as example, the voice prompt function of the picking robot operation information, the voice control of the picking robot movement function, the field grape variety and maturity information recognition and storage and voice broadcast function were realized.It has a certain value for promoting the application of voice technology in agricultural intelligence.
