FlutterTts flutterTts = FlutterTts();
Future _speak() async{
var result = await flutterTts.speak("My first word");
if (result == 1) setState(() => ttsState = TtsState.playing);
}
Future _stop() async{
var result = await flutterTts.stop();
if (result == 1) setState(() => ttsState = TtsState.stopped);
}
flutter_tts_improved
This is a fork of the flutter_tts plugin. It uses the progress reporters of the Utterance APIs, on both Android and iOS.
FlutterTtsImproved tts = new FlutterTtsImproved();
Future _speak() async{
var result = await tts.speak("My first word");
if (result == 1) setState(() => ttsState = TtsState.playing);
}
Future _stop() async{
var result = await tts.stop();
if (result == 1) setState(() => ttsState = TtsState.stopped);
}aws_polly
This plugin is an unofficial AWS Polly client for Dart and Flutter. AWS Polly is an Amazon cloud service that converts text into lifelike speech.aws_polly is a simple wrapper for this service.
It allows to generate a URL given an input text and voice identifier. You must have an AWS account and enable this service to use this package.
Create a client using your new poolId and region:
final AwsPolly _awsPolly = AwsPolly.instance(
poolId: 'us-east-1:xxxx-xxx-xxxxx',
region: AWSRegionType.USEast1,
);Generate a new URL:
final url = await _awsPolly.getUrl(
voiceId: AWSPolyVoiceId.nicole,
input: 'Please convert this text to speech!',
);speech_to_text
This plugin contains a set of classes that make it easy to use the speech recognition features.
import 'package:speech_to_text/speech_to_text.dart' as stt;
stt.SpeechToText speech = stt.SpeechToText();
bool available = await speech.initialize( onStatus: statusListener, onError: errorListener );
if ( available ) {
speech.listen( onResult: resultListener );
}
else {
print("Speech recognition is not allowed on this device.");
}
//stop speech
speech.stop()
