QOS测量工具？
谁能推荐一个好的音频 QOS 监控工具？ 如果它是开源的并且免费提供，那就太好了。其他方面也很好。
我正在尝试测量 PC 和移动设备上的软件电话的 QOS。
Can anyone suggest a good audio QOS monitoring tool?
If its a open source one and freely available, it will be great. Its fine otherwise too.
Iam trying to measure QOS for a softphone on a PC and also on a mobile.

尝试以下链接并搜索 QoS：http://www.slac。 stanford.edu/xorg/nmtf/nmtf-tools.html
请记住，用户对语音通话质量的感知并不是绝对的，因此在对待任何结果时都要牢记这一点。请参阅：http://en.wikipedia.org/wiki/PESQ 了解一种方法（可能是最被接受的方式）来测量和评分语音质量。
您可以绝对测量延迟和数据包丢失，这可能会为您提供所需的信息。
Try the following link and search for QoS: http://www.slac.stanford.edu/xorg/nmtf/nmtf-tools.html
Bear in mind that a users perception of the quality of a voice call is not an absolute thing so treat any results with this in mind. See: http://en.wikipedia.org/wiki/PESQ for one way (probably the most accepted way) to measure and score voice quality.
You can measure absolutely the delay and packet loss which may give you the information you need.
我们开发了一种用于测量音频和视频 QoS 的工具，并拥有一些专利算法来找出视频的 MOS，并使用 E 模型来测量音频 MOS。
它已在 LTE 上的 VoIP 呼叫上进行了测试。
您可以检查 EMpirix 的另一种工具，称为 Hammer Call 分析器或任何 Elecard 工具。
但我不知道这个领域有任何免费软件工具。
We have developed a tool for Measuring QoS for both Audio and Video and have some patented algorithms to find out the MOS for Video and used E-model for Audio MOS.
It has been tested on VoIP calls over LTE.
You can check one more tool from EMpirix called Hammer Call analyser or any Elecard tool as well.
But i don't know of any freeware tool in this domain.
我为会议服务提供商做过语音质量监控系统。使用的工具：Empirix Hammer 和 CallMaster。系统简而言之：每隔一段时间就有两个虚拟参与者加入电话会议。然后他们每个人都说一个短语，另一个人测量 PESQ 分数。结果被发送到另一个监控系统。这很有效。我认为 PESQ 测量是自动化测试的方法。
I have done voice quality monitoring system for conferencing services provider. Tools used: Empirix Hammer and CallMaster. System in a nutshell: every so often two virtual participants called into conference call. Then each of them spoke a phrase and the other one measured PESQ score. Results were sent to another monitoring system. This worked well. I think PESQ measurement is the way to go for automated testing.
