本页面介绍了如何使用 Google Cloud 客户端库以您喜爱的编程语言向 Speech-to-Text 发送语音识别请求。
Speech-to-Text 能够将 Google 语音识别技术轻松集成到开发者应用中。您可以向 Speech-to-Text API 发送音频数据,然后该 API 会返回该音频文件的文字转录。如需详细了解该服务,请参阅 Speech-to-Text 基础知识。
须知事项

If you're using a local shell, then create local authentication credentials for your user account:
gcloud auth application-default login
You don't need to do this if you're using Cloud Shell.
客户端库可以使用应用默认凭据轻松进行 Google API 身份验证,并向这些 API 发送请求。借助应用默认凭据,您可以在本地测试应用并部署它,无需更改底层代码。有关详情,请参阅使用客户端库进行身份验证。
此外,请确保您已安装客户端库。
