Question

我有一个将文字转换为语音的Android应用。数组上的每个单词/字符串都是一个按钮，选中它后会转换为语音。我希望在Flutter中实现这一点。

private TextToSpeech tts;

GridView网格;

String[] words = {

        "Flutter",
        "Dart",
        "React,
        "Java"
};


@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    tts =new TextToSpeech(this, this);
    setContentView(R.layout.activity_main);
    grid = (GridView) findViewById(R.id.grid);

任何人都可以在Dart / Flutter中提供解决方案吗？

谢谢。

Answer 1

您可能会发现Flutter的tts包有用：

https://pub.dartlang.org/packages/tts

这是一个简单的例子

import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';

void main() {
  runApp(new Scaffold(
    body: new Center(
      child: new RaisedButton(
        onPressed: speak,
        child: new Text('Say Hello'),
      ),
    ),
  ));
}

speak() async {
  Tts.speak('Hello World');
}

虽然您可以在此处找到更深入的示例：

https://pub.dartlang.org/packages/tts#-example-tab-

至于连接这些：

这是一个简单的示例，使用列表为列表中的每个字符串呈现按钮，并将onPressed操作呈现为speak单词：

@override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text("The App"),
      ),
      body: new Center(
        child: new Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: _buildWords(),
        ),
      ),
    );
  }

  List<String> words = ['hello', 'world', 'flutter', 'is', 'awesome'];

  List<Widget> _buildWords() {
    return words.map((String word) {
      return new RaisedButton(
        child: new Text(word),
        onPressed: () => Tts.speak(word),
      );
    }).toList();
  }

Answer 2

您不能使用tts包，因为它与Dart 2.0不兼容：

在与Dart 2.0一起使用时，请选择“ flutter_tts”

https://pub.dartlang.org/packages/flutter_tts

     FlutterTts flutterTts = new FlutterTts();

     Future _speak() async{
        var result = await flutterTts.speak("Hello World");
        if (result == 1) setState(() => ttsState = TtsState.playing);
     }

     Future _stop() async{
       var result = await flutterTts.stop();
       if (result == 1) setState(() => ttsState = TtsState.stopped);
     }

     List<dynamic> languages = await flutterTts.getLanguages;

     await flutterTts.setLanguage("en-US");

     await flutterTts.setSpeechRate(1.0);

     await flutterTts.setVolume(1.0);

     await flutterTts.setPitch(1.0);

     await flutterTts.isLanguageAvailable("en-US");

Answer 3

''''import'package：flutter_tts / flutter_tts.dart';'''

for (int i = 0; i < matches.Count; i++)
{
    Console.WriteLine(matches[i].Value);
}

''''如果列表很大，您可以调整持续时间'''

我使用的功能：

Future _speak(String text) async{
    var result = await flutterTts.speak(text);
    if (result == 1) setState(() => ttsState = TtsState.playing);
 }
