Microsoft Sam

Microsoft Sam is the famous Text to Speech voice included with Windows 2000 and Windows XP. He was also included in the TTS Program Speakonia, but his speech patterns differ from the Narrator version. Sam is well known for appearing in hundreds of YouTube videos. He is known to sing, read errors and signs, do voice-overs, and all sorts.

In Downfall parodies
One Downfall parody is made by a Speakonia TTS comedian (also an Unterganger), in which Hitler's sound was changed with that of Sam's.
