我的文字转语音功能不想跟我顶嘴

Question

我的 TextToSpeech android 仍然有问题，我为实现的语音（如 exlipse 也问我）输入了两次按钮，为实现的 OnClickListener 输入了一次按钮，即使我取出按钮的底部操作，它也不想播放， 为什么？我不知道它只是不想说出我的 EditText 字段中的内容，我不知道为什么它不想，而且我已经问过很多次了，但我还没有得到有效的答案。

您是否尝试过仅通过一种方法调用来朗读文本？像这样

mTts.speak(aString, TextToSpeech.QUEUE_ADD, null);

它对我来说效果很好。我使用的初始化和你的一样。唯一剩下的区别是（这不是让 TTS 工作所必需的！）：

        this.speaker.setSpeechRate(0.9f);
        this.speaker.setPitch(0.9f);
