To speak fluently, you need words, loads of them. Words come from 2 sources - listening and reading. 45% of our verbal communication is through listening. To listen successfully, you need to be able to hear first - hear the sounds; sounds in isolation and in group, hear the rhythm, hear the tone, hear the intonation and music of the language. Most students can't hear the sounds or hear them wrong. You hear them wrong - you say them wrong, thanks to old speaking habits. When you say them wrong - you read them wrong too. And when you read them wrong, aloud or silently, again you hear them wrong - again, no memory, no words, no fluency. Solution? BBR - Block old speaking habits, Build muscle memory of new ones and Rewire how you process the sounds in large chunks to better hear, listen, remember more words and get fluent.
