You did not learn vocabulary or grammar as a baby. You learned by listening first. You heard people speak, and your brain slowly figured out the words and patterns. The order matters.
Murmury does not throw away vocabulary or grammar. It moves them after the sound has landed.
Listen first, mimic second, rules last.
The product is modern, but the learning order is old and well proven: hear patterns, copy them, then name the rules.
Infants can track statistical patterns in continuous speech before anyone explains vocabulary or grammar.
