目前我正在开展一个项目，我必须在其中使用 Google Cloud Speech Api 和 TextToSpeech。我尝试使用 RecognizerIntent 解决问题，但我想尝试使用 Cloud Speech。
一些教程 Material 或指南会很棒，我检查了示例应用程序 但我正在寻找教程，指导任何可以解释某些事情的东西。
这是我使用 TTS 和 RecognizerIntent 的工作。

最佳答案
在 Android 上设置 Google Speech cloud 并不是一个简单的 1、2、3 过程，但我会给你一些指导。
- 从这里下载示例项目，使用语音示例。 https://github.com/GoogleCloudPlatform/android-docs-samples/tree/master/speech/Speech
- 设置谷歌云项目，启用 Speech API，并将其链接到 您的 Gmail 帐户的帐单(您获得 60 分钟的免费语音识别 每个月)。
- 生成一个认证json，并放入到“raw”文件夹中 示例项目。
- 在您的计算机上设置 Google 云并获取访问 token 。 将该访问 token 插入您的 SpeechService.java 类。
*关于步骤 3 和 4 的文档: https://cloud.google.com/speech/docs/getting-started
*如果您在尝试将示例项目模拟到您自己的项目中时遇到问题，请检查: Cannot import com.google.cloud.speech.v1.SpeechGrpc in Android
具体步骤太长无法一一列举，我都记不住了，如果遇到具体问题请告诉我。
关于java - 适用于 Android 的谷歌云语音 API，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44506720/
