Question

我正在尝试在服务中运行Text to Speech，而单个字符串运行完美（total = quantity * price - quantity * price * (discount / 100.0); ），当我尝试使用for循环运行它时，它不工作。任何帮助将不胜感激。

tts.speak(text, TextToSpeech.QUEUE_FLUSH, null,null);

Answer 1

实现 TextToSpeech.OnInitListener 并在 onInit 函数内部执行如下操作：

override fun onInit(status: Int) = if (status == TextToSpeech.SUCCESS) {
        val result: Int = textToSpeech.setLanguage(Locale.getDefault())
        if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED
        ) {
            Toast.makeText(applicationContext, "Language not supported", Toast.LENGTH_SHORT).show()
        }

        // Wait 2 seconds to tell the first name
        // Add some silence between the names
        val arrayOfStrings = arrayOf(
            caller_name_label.text.toString(),
            caller_name_label.text.toString(),
            caller_name_label.text.toString()
        )
        var i = 0
        for (name in arrayOfStrings) {

            lifecycleScope.launch {
                delay(2000L)

                textToSpeech.speak(arrayOfStrings[i], TextToSpeech.QUEUE_ADD, null, null)
                textToSpeech.playSilentUtterance(2000L, TextToSpeech.QUEUE_ADD, null);

                i += 1
            }
        }


    } else {
        Toast.makeText(applicationContext, "Init failed", Toast.LENGTH_SHORT).show()
    }

使用它并让我知道

 TextToSpeech tts = new TextToSpeech(this, this);
 tts.setLanguage(Locale.US);
 for (String a :arr) 
{
 tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);
 }

Android Text-to-Speech不适用于循环
