The invention relates to the technical field of computers, and particularly discloses a federal voice intelligent elevator control method, which comprises the following steps of: acquiring voice signal data characteristics and user personalized characteristics to construct a user identification record table, and forming a local training data set; based on the user identification record table, extracting voice signal data features required by model training, and C frames of the front and back voice wake-up modules and C frames of the voice identification module, totally 2C + 1 frames as model input; the model outputs one-hot code coding vectors corresponding to keywords such as door opening, door closing, N-building removal and negative M-building removal; and performing model training of the local speech recognition model based on the user recognition record table, then sending model parameters to the global model, summarizing the model parameters by the global model, issuing the summarized model parameters to each local model, and repeating the step until the model converges. According to the method, elevator voice control signal characteristics and privacy protection requirements can be considered, and the functions of voice control elevator model training, voice wake-up, recognition and control are completed.

    本发明涉及计算机技术领域,具体公开一种联邦语音智能电梯控制方法,控制方法步骤如下:采集语音信号数据特征和用户个性化特征构建用户识别记录表、形成本地训练数据集;基于用户识别记录表,提取模型训练所需的语音信号数据特征,和前后语音唤醒模块的C帧和语音识别模块的C帧,共计2C+1帧作为模型输入;模型输出为“开门、关门、去N楼、负M楼”等关键词对应的独热码编码向量;基于用户识别记录表进行本地语音识别模型的模型训练后模型参数发送至全局模型,全局模型对模型参数汇总并下发至各本地模型,重复此步至模型收敛。本发明能够兼顾电梯语音控制信号特点和隐私保护需求,并完成语音控制电梯模型训练、语音唤醒、识别、控制功能。
