android - 如何在 API 8 中检查 TTS 是否存在

Question

我正在使用 TTS 功能在 Android 中设计一个应用程序。请建议我在 API 8 中找到 TTS 引擎存在的好方法

Answer 1

您使用意图检查文本到语音

Intent intent = new Intent();
intent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
ArrayList<String> languages = new ArrayList<String>();
languages.add("eng-USA"); // Whatever language you want
intent.putStringArrayListExtra(TextToSpeech.Engine.EXTRA_CHECK_VOICE_DATA_FOR, 
                                                    languages);
startActivityForResult(intent, 1);

然后onActivityResult

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    super.onActivityResult(requestCode, resultCode, intent);
    switch (requestCode)
    {
        case 1:
        if (resultCode != TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)
        {
            //  Tts failed go to google play store to download
        }
        break;
    }
}
