在百度Hi的版权页面可以看到其采用的GIPS语音引擎和QQ采用的超级语音是Global IP Sound AB这同一家公司的技术。

    这里所说的GIPS语音引擎，就是QQ超级语音所使用的后台技术。自从QQ超级语音发布之后，引来用户的普遍叫好声。QQ在之前各个网络媒体所作的横向评测中，常常处于比较靠后的位置。用户也常常抱怨QQ的语音有延迟、回声等各种问题。而且，以前QQ语音不支持多人语音，现在QQ 2004 Beta III之后就支持了6方的语音会议功能。那么，这个使得QQ的语音功能发生飞跃的GIPS到底是何方神圣呢？

    GIPS是一家位于瑞典斯德戈尔摩的高技术上市公司，专业从事语音编解码引擎，成立于1999年，目前只有25位员工，但却拥有世界上最顶尖的语音处理和IP电话技术专家。Skype的CEO和创建者尼古拉斯Niklas Zennstrm，对Global IP Sound的评价是：“我们寻找世界上最好的语音引擎来支持我们的软件，感谢Global IP Sound提供给我们。对于我们用于在互联网上打电话的软件，语音质量是非常关键的，而Global IP Sound为我们提供的软件包使得我们能够提供比电话更好的语音质量”

Global IP Sound的主要客户和合作伙伴包括：

　　Nortel、Intertel、Pingtel等电信设备制造厂商，Intel、TI等芯片制造商，此外还拥有类似WebEx、Logitech、Telligent、Skype等互联网应用软件开发商客户。

　　可以看到，作为国内即使通讯的巨头,都不约而同地采用了其技术。百度在以子之矛，攻子之盾？Hi的语音质量会超过QQ的超级语音吗？让我们拭目以待。
