现在的通话还是在采用8kHz的采样率,就是所谓的“电话音质”。随着电话数据传输率的提高,各种互联网服务都在飞速的更新换代,但是为什么没有人关心把通话语音采样率往高提一提的事?
我们经常分不清对方说的F和S、1和7,真TM恶心!

没遇到这种情况过...最多B和D,M和N有时会分不清,但大家都已经约定俗成的会说dog,boy,大m小n了...

这个涉及的问题可就大的去了。受冲击的是整个电信行业,代价可不是一般的大

这个问题, 有一部分的原因是由于语言中某些字或词的发音本身就相近.
并且通信传达的质量与说话的人, 传播工具, 收听的人都有关, 一味的提高语音采样率也未必会起到良好的效果, 并且代价过大.
所以通常的做法(例如电影里面)是, 1念成幺, 7念成拐, 0念成洞等. 英文也是用如楼上说的boy和dog来区分B和D, 其他字母都有一个单独的词来区分.
尤其是我见到在军用方面(电影里面), 对通信的准确性要求如此之高的领域, 都需要用种方式来解决.
PS:建议尽量文明用语.
