    • In an information processing system having an equipment controller for enabling the digitization of complex work processes conducted during testing and/or operation of machinery and equipment, a local wireless communications network is implemented using at least one fixed point wireless communications access station and one or more voice-responsive wireless mobile computing/communications devices that are capable of accurate vocal command recognition in noisy industrial environments. The computing/communications device determines spectral characteristics of ambient non-speech background noises and provides active noise cancellation through the use of a directional microphone and an adaptive noise tracking and subtraction process. The device is carried by a user and is responsive to one or more vocal utterances of the user for communicating data to the information processing system and/or generating operational control commands to provide to the equipment controller for controlling the machinery or equipment.
    • 在具有用于使机器和设备的测试和/或操作期间进行的复杂工作处理的数字化的设备控制器的信息处理系统中,使用至少一个固定点无线通信接入站和一个或多个 语音响应无线移动计算/通信设备,能够在嘈杂的工业环境中进行精确的声带命令识别。 计算/通信设备确定环境非语音背景噪声的频谱特性,并通过使用定向麦克风和自适应噪声跟踪和减法处理来提供主动噪声消除。 该设备由用户携带并且响应于用户的一个或多个声音来传送数据到信息处理系统和/或产生操作控制命令以提供给设备控制器来控制机器或设备。
