Flutter个性化语音处理插件personal_voice_flutter的使用

该Flutter插件提供了在iOS上访问个性化语音的API。

平台支持

使用方法

该插件仅适用于iOS 17或更高版本。

首先，你必须在iPhone的设置中创建一个个性化语音： 设置 -> 辅助功能 -> 语音 -> 个性化语音

创建个性化语音后，确保手机不是静音状态，以便听到语音。

import 'package:personal_voice_flutter/personal_voice_flutter.dart';

...

final permission =
        await _personalVoiceFlutterPlugin.requestPersonalVoiceAuthorization();

if(permission == "authorized") {
    await _personalVoiceFlutterPlugin.speak("A sentence using my voice!");
}

示例代码

以下是一个完整的示例代码，展示了如何使用personal_voice_flutter插件：

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

import 'package:flutter/services.dart';
import 'package:personal_voice_flutter/personal_voice_flutter.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  // 初始化文本控制器
  TextEditingController _textController = TextEditingController(
    text:
        'The Langstroth hive revolutionized beekeeping. Lorenzo Langstroth noticed that the hives beekeepers used at the time were just empty boxes with a lid. When beekeepers would lift the lid to harvest honey they would damage and break the comb that the bees had worked so hard to make. Langstroth noticed that the bees would leave 3/8 of an inch of space in between each section of comb they had built (also known as bee space). Langstroth then designed wood frames that could be lifted out of the hive and inspected individually. This allowed for beekeepers to manipulate, remove, replace and inspect frames for diseases without disturbing the entire hive. A Langstroth hive can either be 8 or 10 frames but all hives and frames have the same standard dimensions if you wish to build your own.', // 设置初始文本
  );

  // 控制文本字段值
  String _textFieldValue = '';

  // 初始化个性化语音插件
  final _personalVoiceFlutterPlugin = PersonalVoiceFlutter();

  [@override](/user/override)
  void initState() {
    super.initState();
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('个性化语音Flutter插件'),
        ),
        body: Center(
          child: Padding(
            padding: const EdgeInsets.all(8.0),
            child: Column(
              children: [
                const Text(
                    '注意：手机不能处于静音状态，且必须已创建个性化语音\n'),
                TextField(
                  controller: _textController,
                  maxLines: null,
                  decoration: const InputDecoration(
                    labelText: '输入文本',
                  ),
                ),
                ElevatedButton(
                    onPressed: askPermission,
                    child: const Text("获取权限")),
                ElevatedButton(onPressed: speak, child: const Text("朗读")),
              ],
            ),
          ),
        ),
      ),
    );
  }

  // 朗读文本
  Future<void> speak() async {
    setState(() {
      _textFieldValue = _textController.text;
    });
    try {
      await _personalVoiceFlutterPlugin.speak(_textFieldValue);
    } on PlatformException {
      print("错误");
    }
  }

  // 请求权限
  Future<void> askPermission() async {
    String result = "";
    // 平台消息可能会失败，所以我们使用try/catch处理PlatformException。
    // 我们还处理了消息可能返回null的情况。
    try {
      result = await _personalVoiceFlutterPlugin
              .requestPersonalVoiceAuthorization() ??
          '未知结果';
      print(result);
    } on PlatformException {
      result = '获取权限失败。';
    }
  }

  [@override](/user/override)
  void dispose() {
    _textController.dispose();
    super.dispose();
  }
