android - Android：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 URL。您需要数据连接才能使用该功能，因此显然他们正在解析服务器端的内容。有人知道这个网址吗？

Answer 1

好的，这就是我在这篇文章的基础上发现的。

以下是语音搜索中各种 HTTP 和 TCP 操作的完整 TCP 转储：

阅读内容很多，但基本上 Android 中发生的事情通过 TCP 将语音数据发送到74.125.142.126端口19294（无论如何在我的情况下）。之后，向 发出 POST 请求74.125.225.176。此后不久，Google 服务器（来自同一个 IP）以可能的选项列表进行响应，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19294端口如何适应事物，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偶然发现同样问题的人。
