文本到语音(TTS)-Android

Question

我是Android平台的新手.现在我正在努力.TTS(Text to Speech)如果我在TextArea中输入文本,我希望在单击"说出"按钮时将其转换为语音.

谁能帮我吗？

Answer 1

Android 1.6+内置了文本到语音.这是一个如何做到的简单示例.

TextToSpeech tts = new TextToSpeech(this, this);
tts.setLanguage(Locale.US);
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

以下是有关如何从Android SDK Manager下载示例代码的说明:

1. 启动Android SDK Manager.

   一个.在Windows上,双击Android SDK目录根目录下的SDK Manager.exe文件.

   湾 在Mac或Linux上,打开Android SDK中tools /目录的终端,然后执行android sdk.

2. 展开最新Android平台的软件包列表.

3. 选择并下载SDK样本.下载完成后,您可以在此位置找到所有样本的源代码:

快速测试 TTS 系统的简约示例：

private TextToSpeech textToSpeechSystem;

@Override
protected void onStart() {
  super.onStart();
  textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                String textToSay = "Hello world, this is a test message!";
                textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
            }
        }
   });
}

如果您不使用本地化消息textToSpeechSystem.setLanguage(..)也很重要，因为您的用户可能并非都将英语设置为他们的默认语言，因此单词的发音将是错误的。但是对于一般测试 TTS 这个片段就足够了
