安卓:谷歌语音识别服务器

Question

我目前正在使用 Google 的 Android SDK 语音识别 API。我想知道的是他们语音识别的网址。您需要数据连接才能使用该功能，因此很明显它们是在服务器端解析内容。有人知道这个网址吗？

Answer 1

好的，这是我在 this 文章的基础上发现的。

这是语音搜索中各种 HTTP 和 TCP 操作的完整 TCP 转储:

要读的东西很多，但基本上 Android 中发生的事情是通过 TCP 将语音数据发送到端口 19294 上的 74.125.142.126(无论如何在我的例子中)。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)以可能的选项列表作为响应，如下所示:

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

似乎涉及的两个 URL 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 是如何适应事物的，但我认为它是语音数据的原始传输，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。
