What version of Premiere Elements? What computer operating system?
Although I think that your question involves the Narration Track and the Narration Tool, the translation was not good. So, I am not sure what your question is?
Please explain further.
If you select the Narration Tool, do you get a message about enabling the Input in preferences - Edit Menu/Preferences/Audio Hardware ASIO and Input Tab.
Are you having problems with the Narration Tool recognizing your microphone? If yes, what microphone do you use for the narration.
Here narration sometimes is called comment, voice.
Please consider, and supply more information.
