Getting Started with Flutter Speech to Text
To implement Flutter Speech to Text in your application, follow these steps:
Step 1: Add the Dependency
First, you need to include the Flutter Speech to Text plugin in your pubspec.yaml
file. This allows your project to access the necessary libraries.
dependencies:
flutter:
sdk: flutter
speech_to_text: ^5.3.0
Step 2: Import the Library
Next, import the library into your Dart file where you want to use the speech recognition feature.
import 'package:speech_to_text/speech_to_text.dart' as stt;
Step 3: Initialize the Speech Recognition
Before you can start recognizing speech, you need to initialize the speech recognition instance and request permissions.
stt.SpeechToText _speech = stt.SpeechToText();
bool _isAvailable = await _speech.initialize();
Step 4: Start Listening
Once the initialization is complete, you can start listening for user input.
_speech.listen(onResult: (result) {
setState(() {
_text = result.recognizedWords;
});
});
Step 5: Stop Listening
Finally, ensure you stop listening once you have captured the necessary input.
_speech.stop();
