"Talk a mile a minute" is an idiomatic expression used to describe someone who speaks rapidly and without pause. Other synonyms for this expression include "talk nineteen to the dozen," "talk at a breakneck pace," or "talk rapidly without any filter." People who talk a mile a minute are often viewed as enthusiastic and energetic, but they can also come across as overwhelming or hard to follow. If a speaker is going too fast, listeners may ask them to slow down, take a breather, or even repeat what they said. Ultimately, finding a comfortable pace of communication is critical for effective conversation.
