Android快速集成微软语音服务（Azure认知服务）

在网上溜了一圈，发现使用微软语音服务（Azure）的文章好少，为之感叹，在国内，百度语音、讯飞语音算是前沿语音技术，使用的公司和人自然不少，不过，在国际语言，小语种这块，还需要努力。刚开始，我也想使用百度语音翻译来着，后面发现集成好麻烦，API请求参数看懵逼了，不要友好，讯飞语音也想要集成了，看了一些demo，仔看看价格，和百度差不多，一直没动手集成，直到后面看到网上说白嫖微软语音合成文章后，大为受惊，操作一番，确实可以哈！一只白嫖一时爽，连续白嫖两周后，啊哈！网站上直接没有体验的入口了，就在不久前，也就是3月16号，俺一看，傻眼了，没了。
好吧！使用两周，感觉语音合成听着挺逼真的，那就注册一个账号，搞起来吧！至于费用什么的，后面再说。

一：注册一个微软账号

1、打开官网语音合成注册一个免费账号
如果打不开，可能需要科学上网，另外需要一个邮箱，最好是谷歌邮箱，其他邮箱如QQ邮箱没试过，不清楚，另外最最最最重要的是要有一张信用卡且支持Visa

2、开通认知服务中的语音Azure 服务
注册账号成功之后来到这个界面

点击左上角+号添加语音服务，获取密钥和位置/区域，推荐亚洲区（East Asia

二：集成语音SDK

1、GitHub示例代码
2、看官方文档，安装语音 SDK
跟着文档走，总结一下就是添加语音依赖库

implementation 'com.microsoft.cognitiveservices.speech:client-sdk:1.26.0'

3、文档中的示例我测试处理，下面放经过我优化调整后的代码，直接可用

import android.util.Log;
import com.microsoft.cognitiveservices.speech.*;
import com.xxx.config.Constants;

        // Required for WordBoundary event sentences.

}

这里，将密钥和位置改成你自己的，Constants.SPEECH_KEY1, Constants.SPEECH_REGION替换成自己的，Constants.SPEECH_NAME这个是设置语言，代码中我写的是日语，其他的你们自己改。
官方文档将语音合成到文件中

总结一下

在写之前雄心勃勃，要写一篇网上较好的微软语音合成文章，写着写着没劲了！
_{哈哈哈哈哈哈哈哈哈哈哈哈哈哈}红红火火恍恍惚惚 ~哈哈哈哈哈哈哈哈哈

好吧~
该总结一下，只说关键词
1、注册微软账号，Visa信用卡
2、开通语音服务
3、复制示例代码，修改密钥等参数
4、运行搞定
