The summarize of the chapter 6 in The Third Ear mentioned：

Pay particular attention to how the language sounds. We will learn to use our mouth, nose and throat to produce the audibols the same way that a native speaker produces them.

Indeed, we can imitate speaking like a parrot.

Traning our mouth with our EARS.

Listening to all the intonations and the smallest of details.

After practicing over and over again, we will be able to speak as well as native speakers.
