Rather, we're moving to a world of technology and input devices designed to fit specific times and places: touch screens on the go, voice activation for TVs, hand gestures to browse a store display with products. 我们正在进入科技和输入设备的新世界,新工具将为特定的时间和地点而设计:随处可见的触摸屏、声控电视、用手势浏览商店产品等。
Others can't talk on the phone to strangers, voice an opinion in a work or social setting or return things to a store because it involves confronting the customer-service person. 有的人不敢在电话中跟陌生人交谈,不敢在工作或社交场合发表意见,或不敢把东西退还给商店因为这涉及到如何面对客服人员的问题。
Packet voice technology converts voice signal to digitized voice packet in certain length, then switches and transmits these packets by means of store and forward. 分组语音技术是指将语音信号转化为一定长度的数字化语音包,采用存储转发的方法以包的形式进行交换和传输的技术。
This method can be used to compress voice and store it continuously, and to save the silence field to transmit data. Compared with traditional method of voice/ data transmission in a frame, this one increases the utilization ratio of the channel. 该方法对语音进行压缩处理,连续存放,收集无声期用于传输数据,与传统的语音/数据同帧传输方法相比,能明显提高信道资源利用率。
