You want to add speech-to-text functionality in your app or just want to see how it’s done. Let’s see how to do it in flutter.

Step 1: Add the plugin

speech_to_text: <latest version>

Step 2: Initialise it

bool _speechEnabled = false;
String _lastWords = '';
final SpeechToText speechToText = SpeechToText();
Future<void> initSpeech() async {
_speechEnabled = await speechToText.initialize();
}

Step 3: Write the start and stop function

///Call when you want to listen 
void startListening() async {
await speechToText.listen(onResult: _onSpeechResult);
}
///Call when you want to stop listening
void stopListening() async {
await speechToText.stop();
}
///It automatically get called when plugin recognize any word.
void _onSpeechResult(SpeechRecognitionResult result) {
_lastWords = result.recognizedWords;
//here you can do anything with recognize words.
}

Step 4: Check the status, if the plugin is enabled or not

String status() {
if (speechEnabled) {
return “Press the button to start speaking”;
} 
else {
return “Speech not available”;
}
}

That’s it, now you can directly use these functions with your UI class.
