jm_baidu_stt_plugin

Flutter bindings for the latest Baidu Speech ASR & wake-up SDKs.

• Android: bdasr_V3_20250507_b610f20.jar + native libs (v3.4.5).
• iOS: ASR_iOS_v3.0.12.0.1285b57 static library & resources.

The plugin exposes a simple Dart API that mirrors the reference native demo so you can initialize the SDK, create recognizer/wake-up engines, and handle streaming status callbacks from Dart.

### Note: Because the Baidu SDK is too large, this plugin package does not include the binary libraries. Please download libBaiduSpeechSDK.a and bds_easr_input_model.dat from the GitHub Release and manually place them in the corresponding directories of your project. ### ### 注意：由于百度 SDK 体积过大，本插件包不含二进制库。请从 GitHub Release 下载 libBaiduSpeechSDK.a 和 bds_easr_input_model.dat，并手动放入项目的对应目录中。 ###

Quick start

JmBaiduSttPlugin.initSDK(
  appId: '<BAIDU_APP_ID>',
  appKey: '<BAIDU_APP_KEY>',
  appSecret: '<BAIDU_APP_SECRET>',
  onEvent: (dynamic event) {
    debugPrint('status=${event['status']} data=${event['data']}');
  },
);

await JmBaiduSttPlugin.create(type: BaiduSpeechBuildType.asr);
await JmBaiduSttPlugin.startRecognition();
await JmBaiduSttPlugin.stopRecognition();

await JmBaiduSttPlugin.create(type: BaiduSpeechBuildType.wakeUp);
await JmBaiduSttPlugin.startMonitorWakeUp();
await JmBaiduSttPlugin.stopMonitorWakeUp();

Event status values

status	meaning
flushData	partial recognition result
statusFinish	final recognition result
volumeChanged	audio level update (0–100)
statusError	recognition/wake-up failure
statusTriggered	wake-up keyword detected

type in the payload is 0 for ASR and 1 for wake-up.

Android integration notes

• minSdkVersion is set to 24 to align with the new Baidu SDK artifacts.
• The plugin bundles the latest bdasr_V3_20250507_b610f20.jar, WakeUp.bin, and all native .so files (armeabi, armeabi-v7a, arm64-v8a, x86, x86_64).
• Required permissions are already declared in the embedded AndroidManifest.xml, but your host app must still request RECORD_AUDIO at runtime.
• If you shrink/obfuscate, keep the Baidu classes (e.g. add -keep class com.baidu.speech.** { *; } to proguard-rules.pro).

iOS integration notes

• The plugin ships Baidu’s static library (libBaiduSpeechSDK.a), headers, wake-word models, and resource bundles from ASR_iOS_v3.0.12.0.
• Add the following to your app’s Info.plist:
  • NSMicrophoneUsageDescription
  • (Optional) UIBackgroundModes → audio if you record in background.
• Run pod install inside the Flutter app’s ios/ folder after adding the plugin so CocoaPods pulls in the updated podspec.
• The plugin includes a Privacy Manifest (Resources/PrivacyInfo.xcprivacy). Update it if your host app has additional data uses.

Example app

example/lib/main.dart contains a basic control panel showing how to:

1. Initialize the SDK with an event listener.
2. Create ASR and wake-up engines.
3. Start/stop recognition and wake-up monitoring while printing native callback payloads.

Replace the placeholder credentials before running on a device.
