This issue has been resolved in the Chinese version Windows XP by changing settings for the language bar. I have not tested whether NVDA can report different Chinese input methods for different keyboard layouts in English version Windows XP. However, I have tested both in English version Windows Vista and Windows 7 and when switching to Chinese keyboard layout, only the keyboard layout is announced and not the specific input method.

To reproduce the issue, add the following input methods in the Text services and input methods dialogue found in regional and language options:
Chinese Traditional Taiwan - New Phonetic
Chinese Traditional - New ChangJie

Then switch to Chinese Traditional Taiwan Keyboard with Alt+Shift. Then use Ctrl+Shift to switch between input methods.

Currently, NVDA correctly announces the keyboard layout and input method when invoking the switch with the system focus on the desktop, in Notepad and in Mozilla Firefox. However, we are finding that some input methods (such as Chinese Traditional new phonetic) is not announced when invoking the switch in certain applications, specifically, in Internet Explorer, Outlook Express, and Microsoft Word. I suspect this has to do with the fact that certain Chinese Input methods such as Chinese Traditional New Phonetic needs to be configured to a certain keyboard layout, which can be changed in the input text services properties dialogue box.
