我使用Google语音Api v1开发了一款应用

https://www.google.com/speech-api/v1/recognize?xjerr=1&client=chromium&lang=＆＃34 + LANGUAGE_CODE;

此链接用于获取响应。它工作正常，但从今天开始它没有工作。我没有收到该链接的任何回复。任何人都有任何想法？有没有替代链接？请帮忙

    // TODO Auto-generated method stub

    String urlString = "https://www.google.com/speech-api/v2/recognize?xjerr=1&client=chromium&lang="

其他人是否有同样的问题？。

Answer 1

最近谷歌关闭了v1 API。 V2 API现在需要密钥，流式传输v2 API每天限制为50个请求。您可以按照此处的说明获取密钥：

http://www.chromium.org/developers/how-tos/api-keys

但无法保证无限制使用。

Answer 2

如果您正在寻找一个Java API检查this。它支持新的Duplex API和V2 API。附带一个方便的教程。如果他们还没有关闭V1，那么在Google关闭之前移植可能是一个好主意。

Answer 3

Chrome的Speech API无法获得额外的配额。请改为Cloud Speech API。

请勿发布任何Chromium群组/邮件列表，以了解有关Speech API的问题。

谷歌演讲Api v1无法正常工作？
