flutter_aiui

Flutter plugin that allows you to use iFlytek's AIUI on Android.

Key Features

• Speech recognition
• Semantics understanding
• Speech synthesis
• Wakeup

IOS

Xcode 7,8 has Bitcode enabled by default, and Bitcode requires support from all class libraries that the project relies on. The AIUI SDK currently does not support Bitcode, and developers need to disable this setting. Simply search for Bitcode in Targets ->Build Settings, find the corresponding option, and set it to NO. As shown in the following figure:

Add the following keys to yourInfo.plistfile, located in<project root>/ios/Runner/Info.plist:

<key>NSMicrophoneUsageDescription</key>
<string></string>
<key>NSLocationUsageDescription</key>
<string></string>
<key>NSLocationAlwaysUsageDescription</key>
<string></string>
<key>NSContactsUsageDescription</key>
<string></string>

Android

• Update your minimum SDK version to 24 in android/app/build.gradle.

android {
    ...
    defaultConfig {
        ...
        minSdkVersion 19 // Change this
        ...
    }
    ...
}

• Add the following permissions to your AndroidManifest.xml, located in <project root>/android/app/src/main/AndroidManifest.xml

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Note: To avoid confusion during packaging or generating APK, please add the following code to proguard.cfg:

-dontoptimize
-keep class com.iflytek.**{*;}
-keepattributes Signature

• Add android:requestLegacyExternalStorage=true of application in AndroidManifest.xml.

<application
        ...
        android:requestLegacyExternalStorage="true">
      ...
</application>      

• Copy the assets folder from the resources downloaded from iFlytek's AIUI application platform to <project root>/android/app/src/main

Usage

Create agent

To use AIUI functionality, you must first create an AIUI agent.

final AiuiParams _params = AiuiParams(
    appId: appId,
    global: GlobalParams(scene: 'main_box'),
    speech: SpeechParams(wakeupMode: WakeupMode.vtn),
  );
await FlutterAiui().initAgent(_params);

Note: To use the wakeup function, simply set the wakeupMode of AiuiParam's speech parameter to WakeupMode.vtn and reinitialize the Agent

Destroy agent

FlutterAiui().destroyAgent();

Add listener

Using a listener to listen for AIUI events

FlutterAiui().addListener(AiuiEventListener(onResult: () => {}));

Remove listener

FlutterAiui().removeListener();

Set parameter

FlutterAiui().setParams(paramsJson);

Start recording

FlutterAiui().startRecordAudio();

Stop recording

FlutterAiui().stopRecordAudio();

Identifying text

FlutterAiui().writeText('xxxxx');

Start tts

FlutterAiui().startTTS();

End tts

FlutterAiui().stopTTS();
