我在开发过程中使用VoiceOver测试可访问性更改。
很多时候，VoiceOver会正确检测到更改，开始阅读它们，但会被新信息中断。因此，当其他更改出现时，重要的信息基本上会被取消。
在我的情况下，我有一个非常重要的警报，但祖先的变化似乎得到了阅读。
如果我能看到VoiceOver说的所有内容的日志，我至少可以确信文本正在被读取并找出一种方法来缓解问题（可能通过延迟）
无论如何都要获得画外音日志？

我不相信有任何方法可以打印日志，但您可以按public class Perspective implements IPerspectiveFactory {
String ID = "bddperspective";
@Override
public void createInitialLayout(IPageLayout layout) {
String editorArea = layout.getEditorArea();
IFolderLayout right = layout.createFolder("right", IPageLayout.RIGHT, .15f, editorArea);
right.addView(DiagramView.ID);
IViewLayout viewLayout = layout.getViewLayout(DiagramView.ID);
if (viewLayout != null) {
viewLayout.setCloseable(false);
viewLayout.setMoveable(false);
}
layout.setEditorAreaVisible(true);
layout.setFixed(true);

将输出保存到音频文件中。如果音频运行得太快，您可以尝试减慢速度或使用某些命令重复输出。此处列出的某些命令可能会有所帮助：
