In a moment that’s captivated millions online, Rachel and Matt Radmacher shared a video of their son Sam, who has autism, showcasing his extraordinary ability to speak in reverse.

Sam, now a teenager, was nonverbal in early childhood but began revealing a rare talent: reciting the alphabet backwards and eventually speaking entire words in reverse. His fascination with reversed language grew, and he now mimics not just the sounds but the vocal intonation as if the word were truly being played backward.

The video, posted to TikTok by Rachel, has garnered over 8 million views, with viewers amazed by Sam’s linguistic precision.

We discovered that Sam could speak in reverse when he was very young. He was nonverbal as far as using verbal for communication. But he could say the alphabet backwards and then he started to say more words in reverse like the word reverse in reverse. He just got really fixated on things being reversed. He also does the inflections with his voice with the way you would say the word backwardsHe’s very talented with other things as well such as music he has perfect pitch and patterns any kind of patterns he can remember.
