154. Sound, Trust & Starting Again with Kate Bradley Chernis

Kate Bradley Chernis spent over a decade figuring out how to use sound to make strangers feel like friends. At Sirius/XM, she was building 200-layer audio files for 30-second commercials. Next, she was infusing radio theory into a generative AI platform before most people knew what generative AI was. Now at Backline EQ, she's using the same instinct, that sound tells you things a transcript never could, to engineer human connection at scale. This conversation covers all of it: the neuroscience, the pivots, and the parts of the journey she rarely shares out loud.

In this episode:

The theater of the mind and why it's the foundation of trust: when your brain constructs the story rather than receiving it passively, it taps into nostalgia, memory, and emotion — the three keystones of why we buy, connect, and believeWhy your eyes lie but your ears don't — Kate's case that sound is the most honest and hardest-to-trick human sense, and what that means for AI tools that rely entirely on transcriptsThe "rules of radio" Kate embedded into Lately's AI — word choices like "remember" versus "don't forget" that trigger different emotional responses, drawn from her training in the neuroscience of music and parasocial connectionHow Backline EQ outperformed the Microsoft/IBM/Google industry-standard language model (MFCC) by 70% in measuring team fit — using voice patterns alone, without transcriptionKate's vulnerable disclosure about a difficult period in her life after eleven years building a company and how her mother's reminder that she was a prodigy at six became the unexpected anchor that helped her begin againThe investor who finally told her to stop inventing something new and just make existing technology better and how that single pivot made everything easier for the first time in over a decade
