好吧，我的大脑已经短路了。我想做的是编写一个程序，让我可以在多次响铃后调用我的计算机。在这一点上，我将能够对着我的电脑说话，并利用电脑的语音识别能力。但是，我的计算机没有通过电话接收我的声音作为“麦克风输入”音频源。很可能是因为 COM4 端口是调制解调器用作其中继源的端口。
目前，我可以通过电脑调用电话，也可以通过电脑接听电话。该计算机当前充当美化电话。两个用户可以来回通话，但 PC 只是坐在那儿，就像第三个人在尴尬的约会中一样。我希望计算机在接听来电者时发挥更积极的作用。
无论如何，我似乎无法敲定代码让我的计算机听到来电者的声音。我只是想打破 AT 命令的僵局，所以请对我温和一些。
下面是from1的代码。任何帮助都会很棒。谢谢!

最佳答案
您不能使用调制解调器(代表 MODulator/DEModulator)来做到这一点。这些旨在将数字通信转换为模拟信号，以便通过电话线传输，然后将模拟信号变回数字信号。你要的是语音处理卡。
我最熟悉的是 Dialogic，但那是大约 10 年前的事了。我快速搜索了一下，发现 Dialogic Diva 2 端口模拟卡正是您想要的那种。您还可以搜索电话板或电话卡。我看到了另一张来自一家名为 Digium 的公司的卡片。
语音处理卡可以安装在 PC 主板的 PCI 插槽中。您将模拟电话线插入卡中。通过开发板的 API，您可以与电话线进行交互，就好像计算机是一部电话一样。 10 年前，您可以检测到人声频率，但语音识别还处于起步阶段。您可以通过电话线播放声音文件(“按 1 获得客户服务”)，然后响应按键音(又名 DTMF)以进行程序控制。
您可以在 PC 上编写任何东西，从简单的语音邮件到非常简洁的多线电话系统。我确信 Dialogic 卡的 API 的功能会大大增加。那就是我下一步要看的地方。调制解调器根本不会执行您希望它执行的操作。
关于C# 调制解调器和 AT 命令，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10593665/
