谷歌语音Api v1不工作？

Question

我用Google speech Api v1开发了一个应用程序

https://www.google.com/speech-api/v1/recognize?xjerr=1&client=chromium&lang="+language_code;

这个链接被用来得到回应。它工作得很好，但就从今天开始它就不工作了。我没有得到任何回应，从这个环节。有人知道吗？有没有其他的链接？请帮忙

还有人有同样的问题吗？。

Answer 1

如果您正在寻找Java API，请检查this一个。它支持新的双工API和V2 API。还提供了一个方便的教程。在Google关闭V1之前迁移可能是一个好主意，如果他们还没有。

Answer 2

最近谷歌关闭了v1 API。V2 API现在需要一个密钥，流式V2 API限制为每天50个请求。您可以按如下所述获取密钥：

然而，没有保证无限使用。

Answer 3

不可能获得Chrome语音API的额外配额。 而是看Cloud Speech API。

不要向任何Chromium组/邮件列表发送有关语音API的问题。
