SpeechSuper SDK Android Java SDK Demo

This demo illustrates how to integrate the SpeechSuper Android SDK into your Android app for pronunciation assessment. Follow these steps to get started:

Step 1: Configure Your Keys

1. Open the file app/src/main/java/com/example/recorder/MainActivity.java.

2. Insert your appKey and secretKey into the following lines:

   public class MainActivity extends AppCompatActivity implements EasyPermissions.PermissionCallbacks {
   
       private static String appKey = "Insert your appKey here";
       private static String secretKey = "Insert your secretKey here";

Step 2: Customize Your Inputs

1. Open the file app/src/main/java/com/example/recorder/TestActivity.java.
2. Modify the input parameters according to your requirements in the startSkegn method:

   public int startSkegn(String engineType, JSONObject requests, CallbackResult callbackResult)  {
      ...

      try {
            JSONObject params = new JSONObject();
            JSONObject appObj = new JSONObject();
            appObj.put("userId", "123");

            JSONObject audioObj = new JSONObject();
            audioObj.put("audioType", "wav");
            audioObj.put("sampleRate", 16000);
            audioObj.put("channel", 1);
            audioObj.put("sampleBytes", 2);
            params.put("audio", audioObj);

            JSONObject vad = new JSONObject();
            vad.put("seek",200);
            vad.put("ref_length",1000);
            params.put("vad",vad);

            params.put("request", requests);
      ...
   

Additional Tips:

1. build.gradle Configuration

Ensure that your build.gradle file includes NDK and sourceSets configurations as follows:

        android {
            ...
            defaultConfig {
                ...

                ndk {
                    abiFilters "armeabi", "armeabi-v7a", "arm64-v8a" , "x86"
                }
            }
            ...
            sourceSets {
                main {
                    jniLibs.srcDirs = ['libs']
                }
            }
        }

        dependencies {
            implementation fileTree(include: ['*.jar'], dir: 'libs')
           ...
        }

2. proguard-rules.pro Configuration

If you're using ProGuard, add the following rules to your proguard-rules.pro file to keep necessary classes and methods:

...
-keep class com.speechsuper.** { *; }
-keepclasseswithmembernames class * {
    native <methods>;
}
