关于android:安卓集成讯飞语音识别并重新封装

在讯飞开放平台注册并实现身份认证, 进入控制台页面创立一个利用

按要求实现填写点击创立即可, 接着进入刚刚创立的利用, 在这里能够看到所有的性能详情.

在右侧可看到要害的 APPID APISecret APIKey

我打算应用三个性能: 语音听写语音合成语音评测, 所以接下来进入聚合 SDK 下载页下载组合 SDK

抉择好利用、平台、须要的 AI 能力后即可下载

下载后将压缩包解压后的目录后果如下:

其中 sample 目录下是一个官网提供的实例 Demo, 咱们能够将其独自用 AS 关上(报错没关系, 能看清代码即可), 之后的封装都是参照官网 Demo 进行的. 官网传送门: 官网文档

SDK 包阐明:

接着将 SDK 导入咱们的我的项目, 首先将在官网下载的 Android SDK 压缩包中 libs 目录下所有子文件拷贝至 Android 工程的 libs 目录下:

用 AS 关上咱们的我的项目, 右键 msc.jar 增加 Add As Library

接着再咱们我的项目的 main 目录下新建 Jnilibs 目录, 将 libs 目录下的两个文件夹拷贝过去:

如运行有报错, 可再在 Module 级的 build.gradle 中增加:

    ....buildTypes {...}
// 新加: 
// 指定 libs 文件夹地位
    sourceSets {
        main{jniLibs.srcDirs = ['libs']
        }
    }

最初, 初始化讯飞 SDK 即可, 倡议在 Application 下初始化:

@Override
    public void onCreate() {super.onCreate();
        mContext = this.getApplication();
        // 这里实现 SDK 初始化，// 请勿在“=”与 appid 之间增加任何空字符或者本义符
        SpeechUtility.createUtility(mContext, SpeechConstant.APPID + "=" + mContext.getString(R.string.APPID));

    }

倡议将常量字符对立寄存在 res/values/string.xml 下

至此, 集成 SDK 已实现, 接下来进行性能封装:

在咱们的包目录下创立一个 utils 包, 官网 Demo 中有两个好用的工具类, 将他们增加到 utils 包下:

在咱们的包目录下新建 iflytek 目录, 用于寄存讯飞相干的类, 首先封装语音听写:

新建接口: RecognizeListener, 新建类: RecognizeSpeechManager

应用(其中采纳了 ViewModel 和 butterKnife):
