How to pronounce surface
The word surface is often mispronounced as [ˈsɜfeɪs], that is, with the second syllable, face, pronounced just like the word face itself. I have the impression that this mistake has become much more frequent here in Germany owing to the increased popularity of Microsoft’s Surface tablet.
The correct pronunciation of surface in both British and American English is [ˈsɜːfɪs] (American English also offers the alternative [ˈsɜːfəs], according to the Longman Pronunciation Dictionary). Listen to the pronunciation of surface here, and compare it to that of face here.
