speech_recognition_kvc 1.0.2

A flutter plugin to use the speech recognition on iOS and Android

speech_recognition_kvc

This is a maintenance fork of the original speech_recognition plugin, which has been discontinued.

🚀 Why this fork?

The original library was no longer compatible with modern Flutter environments. To ensure the sustainability of my project, Wano Collector (Android | iOS), and provide the community with a reliable bridge for speech-to-text, I've updated and maintained this version.

Credits to the original authors for the initial implementation.

Introduction

A flutter plugin to use the speech recognition.

• Basic Example

Installation

1. Depend on it Add this to your package's pubspec.yaml file:

dependencies:
  speech_recognition_kvc: "^1.0.2"

2. Install it You can install packages from the command line:

$ flutter packages get

3. Import it Now in your Dart code, you can use:

import 'package:speech_recognition_kvc/speech_recognition_kvc.dart';

Usage

//..
_speech = SpeechRecognitionKVC();

// The flutter app not only call methods on the host platform,
// it also needs to receive method calls from host.
_speech.setAvailabilityHandler((bool result)
  => setState(() => _speechRecognitionAvailable = result));

// handle device current locale detection
_speech.setCurrentLocaleHandler((String locale) =>
 setState(() => _currentLocale = locale));

_speech.setRecognitionStartedHandler(()
  => setState(() => _isListening = true));

// this handler will be called during recognition.
// the iOS API sends intermediate results,
// On my Android device, only the final transcription is received
_speech.setRecognitionResultHandler((String text)
  => setState(() => transcription = text));

_speech.setRecognitionCompleteHandler(()
  => setState(() => _isListening = false));

// 1st launch : speech recognition permission / initialization
_speech
    .activate()
    .then((res) => setState(() => _speechRecognitionAvailable = res));
//..

speech.listen(locale:_currentLocale).then((result)=> print('result : $result'));

// ...

speech.cancel();

// ||

speech.stop();

// Handle recognition errors
_speech.setErrorHandler((SpeechRecognitionError e) => print('error: $e'));
