Research On The Intelligent Steward To Prevent Ad Based On The Individual Needs Of The Elderly

Alzheimer's disease(AD)is a common disease,which is characterized by memory disorder,aphasia,loss of use,blindness,impairment of visuospatial skills,executive dysfunction,personality and behavior changes and so on.The cause of ad is not clear up to now,but effective brain training can prevent Alzheimer's disease,but how to target different old people anytime and anywhere Different brain training has become an urgent problem.This paper will focus on the above problems,study the personalized needs of the elderly,carry out intelligent speech recognition for ad prevention products,design the voice model of the elderly,design the intelligent housekeeper model.This paper studies the individual needs of the elderly based on Kano model.This paper analyzes the information of the elderly's individual needs,classifies the elderly's individual needs semantically,and introduces the characteristics and mapping relationship of the individual needs model.And get the design parameters that need to be improved.Based on the deep learning theory,the design parameters are analyzed.Combining with the prevention of ad products,the deep learning theory is described and the design steps are determined.According to the speech characteristics of the elderly,determine the pre emphasis mode required by the product interaction design.By comparing the smoothness of the window function,select the window function required by framing and windowing,and carry out speech endpoint detection.Based on ann-hmm neural network model,establish the acoustic model of the elderly,determine the activation function,so that the product can basically realize the long and short speech segment interaction recognition of the elderly Reply function.This paper uses the theory of design to design the model of prevention ad intelligent housekeeper.Firstly,it designs the structure layout of the product,determines the connection layout of each part.Finally,color,material and surface treatment process,and the product effect drawing and display board are designed.
