Question

我目前正在使用Google的Android SDK语音识别API。我想知道的是他们的语音识别的URL。您需要数据连接才能使用该功能，因此显然它们正在解析服务器端的问题。有谁知道这个网址？

Answer 1

好的，这是我发现的，基于this文章。

以下是进入语音搜索的各种HTTP和TCP操作的完整TCP转储：

阅读起来很多，但基本上在Android中发生的事情会通过TCP将语音数据发送到端口74.125.142.126上的19294（无论如何我都是这样）。之后，向74.125.225.176发出POST请求。此后不久，Google服务器（来自同一IP）响应了一系列可能的选项，如下所示：

.testing.....D..?..
.test...........
.testting...........
.texting...........

似乎涉及的两个网址是www.google.com/m/appreq/vs和 www.google.com/m/voice-search。

这似乎是它的要点。基本HTTP操作（GET / POST）请求。我不确定端口19294是如何适应的，但我认为这是语音数据的原始传输，它通过HTTP处理和返回。我希望这可以帮助任何遇到同样问题的人。
