Canalization is a concept in developmental biology and psychology that refers to the tendency of a species to produce a phenotype regardless of variability in its environment or genotype. In the context of infant vocalizations, this means that all infants, regardless of their specific genetic makeup or the environment they are born into, will initially produce similar sounds. This is because the development of early vocalizations is highly canalized, following a species-specific pattern that is relatively unaffected by external factors.
