Beyond Words Ep. 30 | Active Inference, Language, and the Predictive Brain with Dr. Karl Friston

In this episode of Beyond Words, host Garrett Oyama speaks with Dr. Karl Friston, one of the world’s most influential neuroscientists and the architect of the free energy principle, about how active inference might help us understand human communication, language development, and speech-language intervention.

In a conversation that brings Friston’s theoretical work into the world of speech and language, they explore how communication allows us to share beliefs, resolve uncertainty, and construct shared models of the world. Dr. Friston explains the foundations of active inference before discussing conversational turn-taking, the coordination of speaking and listening, and potential implications for understanding autism and communication disorders.

The conversation then turns to early development and intervention. Why do babies experiment with their voices when nobody is listening? How might curiosity and exploration drive language learning? And what would speech therapy look like if we thought of children as active explorers rather than passive recipients of information?

Finally, they discuss joint attention, caregiver-child interaction, the potential effects of digital devices on communication development, and the future of artificial intelligence.
