If you have been listening to oral argument recordings and have been wondering to whom a particular voice belongs, you should use the link to the audio key page, located on the upper right-hand portion of the home page. The audio key has been updated to include the voices of the recently appointed Federal Circuit judges.
If you are curious which judge is speaking during an oral argument recording, my suggestion is to:
(1) pull up the opinion;*
(2) note from the opinion who the judges on the panel are; and
(3) use the sound bites on the audio key page to identify the speaker.
*Alternatively, if no opinion has issued and the case was recently argued, you can likely determine the panel from the “Upcoming Oral Arguments” link on the Federal Circuit web site.
