出站呼叫时确定是否应答电话 [英] Determine if answerphone when outbound calling

问题描述

我们有一个应用程序可以启动出站呼叫，并希望尽可能避免留下语音邮件。我们已按照以下文章尝试实施（ http://msdn.microsoft.com/en- us / library / hh530044.aspx ）
但是发现这非常不可靠。文章提到了设计用于确定呼叫是否已由机器应答的软件，但是我无法找到任何此软件。有没有人有任何
这样的软件经验，或者有人可以建议一个可靠的方法吗？

We have an app which initiates an outbound call and would like to avoid leaving voicemail messages if at all possible. We have tried implementing as per the following article (http://msdn.microsoft.com/en-us/library/hh530044.aspx) however have found this to be very unreliable. The article mentions software designed to do the job of working out whether the call has been answered by a machine, however I have been unable to find any of this software. Does anyone have any experience of such software or could anyone suggest a reliable approach to this?

推荐答案

有一篇相关文章试图做通过实际使用语音识别语法来区分答录机和人类，可以做得更好。 您可以尝试这种方法，看看您是否获得了更好的结果。 链接到：

演练：检测应答机  但是，区分绝不是100％。 

There's a related article that tries to do a better job by actually using a speech recognition grammar to distinguish between an answering machine and a human.  You can try that approach and see if you get better results.  Link to that is: Walkthrough: Detect an Answering Machine   However, making the distinction is never 100%. 

如果您搜索"应答机检测"，在你最喜欢的搜索引擎中，你会获得大量的点击率。 根据您连接到PSTN的方式，一些网关（如Audiocodes）在其框中提供此功能。

If you do a search for "answering machine detection" in your favorite search engine, you will get lot's of hits.  Depending on how you are connecting to the PSTN, the some of the gateways, like Audiocodes, offer this feature in their boxes.
