语言是我们与生俱来的交流方式。然而，它具有局限性，例如作为广播过程，它的范围有限，并且只能在空气中工作。在这里，我们将探讨两种技术的结合，以实现自然的有针对性的通信与潜在的应用程序在协调任务或私人对话。为了检测单词，我们测量了说话时面部肌肉产生的生物电信号。一个由4个表面电极组成的肌电系统在识别10个单词时的准确率为80%。更重要的是，该系统在区分口头和无声的话语方面同样有效。为了传输单词，我们使用了声音通过超声波的现象，在窄波束内产生可听的声音。我们建立了一个超声波发射器的相控阵列，能够发出声音，可以电子操纵，而无需物理移动阵列。提出了两种结合词的联合收割机检测和转移的原型，并分析了它们的局限性。
Speech is our innate way of communication. However, it has limitation such as being a broadcast process, it has limited reach and it only works in air. Here, we explore the combination of two technologies for realizing natural targeted communication with potential applications in coordination of tasks or private conversations. For detecting words, we measure the bioelectric signals produced by facial muscles during speech. An electromyographic system composed of 4 surface electrodes had an accuracy of 80% when discriminating between 10 words. More importantly, the system was equally effective in discriminating spoken and silently mouthed words. For transferring the words, we used the sound-through-ultrasound phenomenon to generate audible sound within a narrow beam. We built a phased array of ultrasonic emitters, capable of emitting sound that can be steered electronically without physically moving the array. Two prototypes that combine detection and transfer of words are presented and their limitations analysed.
