What if you could understand the call of a humpback whale, or the chatter of dolphins, not as distant echoes, but as something almost… conversational? In How to Speak Whale, filmmaker and former biologist Tom Mustill takes us from a freak kayak encounter with a breaching whale to the frontiers of AI-driven animal communication—blending wonder, science, and a quest that feels as emotional as it is groundbreaking .
This isn’t a dry exploration of biosonar and whale song frequencies—it’s a human story wrapped in ocean spray and astonishment. Mustill was forever changed in 2015 when a forty-ton humpback breached over his kayak, nearly ending his life—yet sparking a life’s obsession with what whales mean when they sing (). What follows is part memoir, part scientific detective tale, as he meets marine biologists, acoustic researchers, and AI experts attempting to translate cetacean communication into something we can grasp.
Whales—giant, social mammals with “virtuoso voices and long, highly social lives”—offer a realistic shot at bridging that interspecies gap . Mustill guides us into labs where whale songs are mapped, decoded, and run through neural networks, revealing patterns that hint at grammar, dialects, even elusive emotional content. The excitement builds naturally: each new insight feels like a potential breakthrough in a conversation millions of years in the making.
What makes How to Speak Whale sing is Mustill’s ability to translate complex science into gorgeously clear storytelling. You’re not just learning about spectrograms—you’re feeling the thrill that comes when machine learning actually “hears” the songs, and when researchers catch whispers of whale curiosity and culture in the data. Mustill’s voice is open and awestruck, yet grounded in rigorous reporting and a genuine respect for the creatures he’s chasing in soundwaves.
There’s also a broader question at the heart of the book: what does it mean to really listen to another species? Mustill’s journey reflects a growing movement in animal intelligence studies—one that challenges human exceptionalism and asks whether we’ve been too deaf to the world’s other intelligences .
By the final pages, How to Speak Whale feels like a manifesto for empathy as well as a scientific adventure. It leaves readers pondering our relationship with Earth’s largest creatures, the ethics of AI interpretation, and the hope that we might one day bridge the silence between species.
If you’ve ever watched a whale breach and wondered what song it sings into the void—this book is your first invitation to listen back. It’s a blend of sea-blasted memoir, cutting-edge science, and a quietly potent message: the ocean holds more conversations than we’ve known how to ask.
