Study Finds Dogs Share Humans' Preference for Consonant-Rich Speech
Researchers discovered that domestic dogs, like humans, process speech more efficiently when it contains recurring consonant patterns.
A new study released in Science reveals that domestic dogs exhibit the same consonant-bias in speech perception that humans do. Researchers recorded brain activity from 20 adult participants and 20 companion dogs while they listened to three-syllable nonsense strings organized by consonant patterns, vowel patterns, or no pattern. Both species showed superior word segmentation when the underlying structure was consonant-based, indicating that everyday exposure to human speech can remodel neural processing.
The work, led by Attila Andics of the University of Loránd, highlights parallels with AI models that also prioritize consonants for word similarity judgments. Co-author Dorottya Rácz emphasized the surprising cross-species similarity, and Juan Manuel Toro noted that the bias likely stems from shared auditory mechanisms rather than language complexity. The study adds to a growing body of research on how language exposure influences brain function across animals and machines.
Why it matters
The research shows that regular human speech can shape animal cognition, deepening our understanding of language processing across species.
