Abstract：Ariceharvesterstatecontrol methodbasedonEnglish speech signal recognitionisproposed toaddress the problemofdynamicchangesintheworkloadofharvesterswithvaryingworkdensity，whichmakesitimpossibleto control theharvesterstateinrealtime.Basedonthespeech motioncouplingcharacteristics inthethree-dimensional workspace，ariceharvesterstatusEnglishspeechsignalrecognitionmodel isconstructed.Bycalculatingtheprobability distributionandtransitionprobabilitymatrixoftheharvestersworkingstateintheinitialstate，themodelcoeffcientsfor eachinstructionwordareestablished.Combining themixtureGaussiandistribution fiting methodtoobtainspeechsignal recognitionresults.From the experimental results，itcan beseen thatthis method hasa maximumerrorof 0.1kg/s （20号 betweenthe feeding amountandtheideal value，andthe totaldelayisonlyO.1s.Ithasprecisecontrolefect and real-time response capability.
