TALKING BACKWARDS (Backwards Banter Brain Testing) - Smarter Every Day 168

TL;DR

Kurt Quinn talks backwards by reversing speech phonetically rather than simply reversing written letters. Destin tests this practiced skill with increasingly difficult tasks, from single words and animal distractions to playing the banjo while responding. The episode also explains why plosives must be simulated and contrasts English’s 26 letters with the International Phonetic Alphabet’s 107 symbols. Read on to see what these tests reveal about speech and attention.

Transcript

hey it's me Destin welcome back to smarter every day. A while back on the smarter every day subreddit someone made a post that said something like no one ever believes that I can talk backwards. This caught my eye and I watched the video and it was fascinating it's a skill this guy has clearly worked very very hard on it. If you remember in the bac... Read More

Key Insights

• 👂 Talking backwards requires phonetically recreating sounds in reverse order.
• 👂 Certain sounds, like plosives, are challenging to pronounce accurately backwards.
• 🧠 Multitasking and distractions can affect the brain's ability to maintain the backward talking skill.
• 💦 Kurt's ability to talk backwards is a result of hard work and practice.
• 😯 The brain's algorithms for speech production are fascinating and complex.
• 😯 The physical limitations of producing sounds backwards highlight the intricacies of speech.
• 😋 Talking backwards requires the coordination of the tongue, teeth, and lips to control airflow and pressure.

Questions & Answers

Q: How does Kurt Quinn talk backwards?

Kurt phonetically recreates speech sounds in reverse instead of merely reading a word’s letters backward. His brain uses a practiced process that coordinates his tongue, teeth, lips, airflow, and pressure.

Q: Is talking backwards a talent or an acquired skill?

Kurt describes talking backwards as a skill that can be acquired. Destin also emphasizes that Kurt has worked very hard to develop it.

Q: How does Destin test Kurt’s backwards-talking skill?

Destin begins with one word and gradually increases the difficulty. He introduces longer phrases, animals, banjo playing, and other distractions to see whether Kurt’s brain becomes task-saturated.

Q: Why does talking backwards require more than reversing letters?

Spoken language is made from sounds, so Kurt must reverse the sounds produced by the letters rather than their written order. Destin illustrates the complexity by contrasting the English alphabet’s 26 letters with the International Phonetic Alphabet’s 107 symbols.

Q: Why are plosive sounds difficult to reproduce backwards?

Plosives are created by pressurizing the mouth and suddenly releasing the air, producing a sharp sound followed by airflow. Because the mouth cannot repressurize instantly within milliseconds, Kurt uses tricks to simulate how a reversed plosive should sound.

Q: What role do the tongue, teeth, and lips play in speech?

The tongue and teeth interact to restrict or permit airflow in particular directions. The lips can hold back pressure and release it suddenly, making their coordination important for producing and reversing speech sounds.

Q: What happened when Kurt talked backwards while playing the banjo?

Kurt initially felt comfortable playing a song he had performed a million times. When Destin added a word for him to reverse, Kurt said his brain forgot about the song, showing how the added task disrupted his performance.

Q: What was the grand-finale distraction test?

After a safety brief, Kurt was placed between two rifles firing at bottles while a drone recorded overhead. Destin notes that an AK firing resembles a plosive because both involve a rapid release of pressurized gas.

Summary & Key Takeaways

• Kurt Quinn can talk backwards and Destin wants to test the limits of this skill.

• Starting with one word, Destin gradually makes the tasks more challenging, including holding animals and playing the banjo.

• The brain has a complex algorithm to recreate sounds backwards, and certain sounds, like plosives, require specific techniques to be pronounced backwards.
