There exists only one recording of Hitler's normal voice and it's absolutely mindblowing.
It's known as the "
Hitler and Mannerheim recording" and took place in Mannerheim's private wagon on a secret visit made to Finland by Hitler to honor Mannerheim's 75th birthday on June 4, 1942. In this wagon, a large and visible microphone had been set up by Thor Damen, a sound engineer for the Finnish broadcaster Yleisradio (YLE), who had been assigned to record Hitler's official speech and birthday message to Mannerheim. After the official speeches, Damen continued to record the now-private conversation, with Hitler unaware that the conversation was still being recorded. After eleven minutes, Hitler's SS guards realized what Damen was doing and made a cutthroat gesture to demand that he cease recording. The SS guards demanded the tape be destroyed, but YLE was allowed to keep the tape in a sealed container with the promise that it never be opened again. The tape was given to the head of the State Censors' Office, Kustaa Vilkuna, returned to YLE in 1957, and made publicly available a few years later. It is the only known recording of Hitler speaking in an unofficial tone and one of the very few recordings in which Hitler may be heard delivering a narrative without raising his voice.
Listen to the recording here and prepare to have your mind blown (the recording is a little fuzzy at first, but his voice becomes much more clear a little later in the recording):
For some reason, it's common to assume that Hitler had a high-pitched, whiny voice. But his voice was actually
extremely deep. He sounded like James Earl Jones or Darth Vader.
The comments on the video above and other parts of the internet where the recording has been shared largely express absolute and utter levels of shock. Most seem to agree that his voice was much, much deeper than they expected.
The funniest story I've seen regarding this recording was someone on Quora claiming that when they listened to this recording on their laptop, their girlfriend (who was nearby) said something like "who is that?" That is the sexiest voice I have ever heard," only to be in utter disbelief and shock when he revealed to her that the voice belonged to Hitler.
But it's definitely easy to see how he was able to attract so many people to his cause with a voice like that. I guess being utterly charismatic is unfortunately common in the world's most nefarious super villains.
