Getting Started

1. add ogg_opus_player to your pubspec.yaml

     ogg_opus_player: $latest_version
   

2. then you can play your opus ogg file from OggOpusPlayer

   import 'package:ogg_opus_player/ogg_opus_player.dart';
      
   void playOggOpusFile() {
     final player = OggOpusPlayer("file_path");
      
     player.play();
     player.pause();
      
     player.dipose();

AudioSession

For android/iOS platform, you need to manage audio session by yourself.

It is recommended to use audio_session to manage audio session.

Speech recognition

Speech recognition is currently only supported on iOS 10.0 or later and macOS 10.15 or later.

final status = await OggOpusSpeechRecognizer.authorizationStatus();
await OggOpusSpeechRecognizer.requestAuthorization();

final transcription = await OggOpusSpeechRecognizer.transcribeFile(
  'file_path.ogg',
  localeIdentifier:
      WidgetsBinding.instance.platformDispatcher.locale.toLanguageTag(),
);
print(transcription.text);

For live recording transcription, enable transcription when creating the recorder:

final recorder = OggOpusRecorder(
  'file_path.ogg',
  enableTranscription: true,
  transcriptionLocaleIdentifier:
      WidgetsBinding.instance.platformDispatcher.locale.toLanguageTag(),
);

final subscription = recorder.transcriptions.listen((transcription) {
  print(transcription.text);
});

recorder.start();

On macOS, requesting speech recognition permission from Flutter tooling or VS Code can crash before Dart receives an error. Start the app from Xcode when granting speech recognition permission for the first time.

Linux required

sudo apt-get install libsdl2-dev
sudo apt-get install libopus-dev

iOS/macOS required

Speech recognition also requires NSSpeechRecognitionUsageDescription:

    <key>NSSpeechRecognitionUsageDescription</key>
    <string>Example uses speech recognition to transcribe recorded voice.</string>

for macOS, you also need update your DebugProfile.entitlements and ReleaseProfile.entitlements with the following:

    <true/>
