SpeechToTextProvider class

Simplifies interaction with SpeechToText by handling all the callbacks and notifying listeners as events happen.

Here's an example of using the SpeechToTextProvider

var speechProvider = SpeechToTextProvider( SpeechToText());
var available = await speechProvider.initialize();
StreamSubscription<SpeechRecognitionEvent> _subscription;
_subscription = speechProvider.recognitionController.stream.listen((recognitionEvent) {
  if (recognitionEvent.eventType == SpeechRecognitionEventType.finalRecognitionEvent )  {
      print("I heard: ${recognitionEvent.recognitionResult.recognizedWords}");
    }
  });
speechProvider.addListener(() {
  var words = speechProvider.lastWords;
});

Returns true if SpeechToText has a previous error.
no setter
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
hasResults → bool
Returns true if lastResult has a last result.
no setter
isAvailable → bool
Returns true if the provider has been initialized and can be used to recognize speech.
no setter
isListening → bool
Returns true if SpeechToText is listening for new speech.
no setter
isNotAvailable → bool
Returns true if the provider cannot be used to recognize speech, either because it has not yet been initialized or because initialization failed.
no setter
isNotListening → bool
Returns true if SpeechToText is not listening for new speech.
no setter
lastError → SpeechRecognitionError?
Returns the last error received.
no setter
lastLevel → double
Returns the last sound level received.
no setter
lastResult → SpeechRecognitionResult?
Returns the last result received.
no setter
locales → List<LocaleName>
Returns the list of locales that are available on the device for speech recognition.
no setter
runtimeType → Type

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
cancel() → void
Cancel a current active listening session.
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
initialize({dynamic debugLogging = false, Duration finalTimeout = SpeechToText.defaultFinalTimeout, List<SpeechConfigOption>? options}) → Future<bool>
Initializes the provider and the contained SpeechToText instance.
listen({bool partialResults = true, dynamic onDevice = false, bool soundLevel = false, Duration? listenFor, Duration? pauseFor, String? localeId}) → void
Start listening for new events, set partialResults to true to receive interim recognition results.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
stop() → void
Stops a current active listening session.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
