| The problem of agricultural production has been plaguing farmers’ friends.At present,this problem is mainly solved by face-to-face communication.The interaction and sharing of agricultural information can help farmers greatly improve the problems in agricultural production.Today is the era of informationization.It is not limited to face-to-face communication.It is to use information technology to achieve rapid sharing of agricultural information and timely and effective solutions.Problems in agricultural production.The main research content in this paper has the following two parts:First,the acquisition of agricultural product trading information.Farmers often have the demand to sell their own vegetables.Due to their limited sales channels,the price of the goods in the market cannot be accurately grasped and is often sold at a lower price.Through this function,the price,location and time of recent agricultural product acquisitions are obtained on the agricultural product trading website by means of voice search.And by geographical location,according to the location of the acquisition,the information is broadcast from near to far.Greatly improve farmers’ grasp of agricultural product market prices,broaden the trading channels of agricultural products,and increase farmers’ income.Second,the voice questioning subsystem.In the production process of agricultural products,problems are often encountered,and there are fewer opportunities for face-to-face communication with experts.The operation of agricultural production expert systems is relatively complicated,and many problems cannot be solved in time,resulting in reduced crop yields,and problems such as pests and diseases cannot be prevented in time.The voice questioning subsystem can recognize the input question and convert it into text to submit to the expert system,wait for the expert to reply,and finally report the reply result in the form of voice.The operation of farmers has been simplified,and the problems of agricultural products in agricultural production have been solved in a timely and effective manner.The APP extracts the valid information contained in the voice through a fixed man-machine dialogue mode,performs the corresponding information acquisition operation according to the valid information,and synthesizes the operation result,and broadcasts the message at the user end.It can effectively avoid the problem of low literacy rate of farmers,and can obtain existing agricultural information in time,greatly improving the timeliness and convenience of handling problems in agricultural production.Aiming at providing more convenient interaction methods,an agricultural information query APP based on voice interaction was designed. |
