android - 如何使tts跳过字符串android中的特定单词

Question

这是我要问的第一个问题。我开发了一个 android 应用程序，它使用广播接收器接收传入的短信，然后将消息与预定义的审查词数组列表进行比较，然后用 * 替换短信中的审查词现在我想要文本到语音来说出消息内容，但不要说出被审查的单词 *。我只需要一个指南或如何为此创建逻辑。任何帮助将是极大的帮助。我来到这里希望能在这里找到帮助。谢谢你

这是我的代码

Answer 1

所以经过大量的努力，我找到了一个不错的方法来做到这一点。创建另一个字符串并将结果存储在没有攻击性单词的字符串中，并用 *** 显示字符串但读取干净的字符串..

示例代码是

//Show message
        body.setText(strBody);

        //Extract string without offensive words

        cleanString = strBody;

        cleanString = cleanString.replace("*","");

        //=========================

然后像这样说

public void speakUnknownNumber()
    {
        tts.setPitch(1.3f);
        tts.setSpeechRate(0.7f);
        tts.speak("\n\n"+"Message\n\n"+cleanString,TextToSpeech.QUEUE_ADD,null,null);
    }

**输出strBody = What the **** ==> here **** are hellcleanString = 什么**

所以 tts 只会说干净的话。

希望这对遇到同样问题的人有所帮助。干杯
