background_stt #

Speech-to-Text, Text-to-speech, Interactive Voice commands

[Android Support Only]

pub package

An flutter plugin that runs Speech-to-Text continously in background. This plugin operates in 2 modes:

1. STT Mode

Voice commands will be recognized in background and sent to Flutter app.

2. Confirmation Mode

Voice commands will be recognized and if confirmation was requested for the command, confirmation flow will begin. Once user has provided with "Positive" or "Negative" reply, confirmation mode will end delivering voice input results to flutter app.

Speech results will be delivered in real-time to the flutter app.

How to use it? #

Start Speech-to-Text Service


Note: Service will keep on running once it is started and can only be stopped by calling stop service method.

 var _service = BackgroundStt();

 _service.startSpeechListenService;
    _service.getSpeechResults().onData((data) {
      print("getSpeechResults: ${data.result} , ${data.isPartial}");
    });

Setup Intent for Simple Confirmation


This can be useful for simple decisions.

    _service.getSpeechResults().onData((data) {
          if (command == "start") {
          _service.confirmIntent(
              confirmationText: "Do you want to start?",
              positiveCommand: "yes",
              negativeCommand: "no");
        }
    });

  _service.getConfirmationResults().onData((data) {
      print(
          "getConfirmationResults: Confirmation Text: ${data.confirmationIntent} , "
          "User Replied: ${data.confirmedResult} , "
          "Is Confirmation Success?: ${data.isSuccess}");
    });

Setup Intent for Voice-Input Confirmation


This can be useful for taking voice input from user and then confirming that input from user by voice command verification.

    _service.getSpeechResults().onData((data) {
          if (command == "address") {
            _service.confirmIntent(
                confirmationText: "What is the address?",
                positiveCommand: "yes",
                negativeCommand: "no",
                voiceInputMessage: "Is the address correct?",
                voiceInput: true);
          }
    });

  _service.getConfirmationResults().onData((data) {
      print(
          "getConfirmationResults: Confirmation Text: ${data.confirmationIntent} , "
          "User Replied: ${data.confirmedResult} , "
          "Voice Input Message: ${data.voiceInput} , "
          "Is Confirmation Success?: ${data.isSuccess}");
    });

Cancel Confirmation in progress


  await _service.cancelConfirmation;

Stop Speech-to-Text Service


  _service.stopSpeechListenService;

Pause Speech-to-Text Listener


  await _service.pauseListening();

Resume Speech-to-Text Listener


  await _service.resumeListening();
